Today’s HARTMANN VALVES GmbH belongs to the leading manufacturers in the areas of ball valves, pigging valves, and well flanges. A worldwide presence in the crude oil, natural gas, petrochemical industry, power plant technology as well as geothermal and other renewable energies is our reference.
Designed to individual customer requirements, Hartmann ball valves guarantee the highest levels of safety and availability – even under extreme operating conditions. As a reliable shut-off valve, they resist aggressive media, extreme pressures and temperatures or frequent actuating operations. The metal-to-metal sealing between ball and seat rings with high quality hardfacing provides an especially long service life and minimises maintenance requirements.
The ball valves are equipped with hand lever or gearbox for manual operation. Automatic operation by means of electric, pneumatic or hydraulic actuators. Configuration variants e.g. rapid close, fail-safe-open, fail-safe close and high cycle with ≥200,000 actuations per year. We develop tailor made solutions for special process requirements.
HARTMANN VALVES valves of the AST series are designed for use as high-pressure valves. With our unique and entirely metallic sealing systems they are equally suitable as reliably sealing shut-off valves for liquid as well as gaseous media with solid particle components.
HARTMANN VALVES ball valves of the ASF series – for reliable sealing function, even under more challenging operating conditions These HARTMANN VALVES ball valves with metallic sealing systems are suitable for gaseous and liquid media with solid particle components.
HARTMANN VALVES ball valves of the TBV series find use when strict safety regulations require a dual pipeline shut-off. Designed for these applications, the HARTMANN VALVES TBV series combines two complete and independent shut-off systems (“Twin Ball Valve“) in just one housing: 0-bubble seal tight, and testable between the shut-off systems. The compact design facilitates operational reliability, and furthermore helps in saving space and lowering costs due to lowered material demands.
Hartmann Valves ball valves are also used successfully, in a design modified by our engineers, in the most specialized application areas:
Hartmann Valves of the Gate Valve series, type HGV, complement our ball valves. Solid shut-off slider, made of a single forged steel body from European forges and equipped with a full-gate, two seating rings, as well as the use of proven seal technology provide the guarantee for secure deployment and a long service life.
Hartmann pig valves offer a space- and cost-saving substitution for expensive pig trap systems. In addition to the classic application as a shut-off valve, the pig ball valve functions as a pig launcher and receiver.
A laterally integrated lock gate, which is locked and secured by a bayonet system, allows pigs to be inserted and removed easily, quickly and safely.
Our API 6A-compliant wellheads are designed to meet the highest standards and have been used for decades in oil and gas production, storage technology and deep geothermal applications. Made of high-quality materials, they are equipped as standard with gas-tight, purely metallic sealing ball valves. An integrated design not only minimizes height and weight, but also saves a lot of money by saving on flange connections. For the assembly service, repairs and maintenance an experienced service team is available around the clock.
Designed to suspend casing/tubing in a pre-tensioned state. Allows to run the pipe below landing level, than pool to required tension and suspend. Depending on the casing string and the production casing string, a defined or an infinite underpinning is possible.
Hangers of mandrel or slip type are designed for suspension of the pipe strings in the wellhead systems. With shape hangers the connection is established through external – internal threads, or through a welded connection, in the case of clamp hangers by means of wedge segments.
Block type x-mas tree designed for two or more x-mass tree valves in same body block. Can be implemented correspondingly in the most different configurations, according to customer specifications. Besides compact design and the use of forged steels, combinations of proven ball valves and gate valves are possible, or can be equipped completely with ball valves and gate valves. In order to facilitate operability of manual valves, drives, if used, can also be mounted on the backside.
Gear of the Special components series are tailored specifically to your requirements, and designed with API 6A or other valid norms in mind. Acceptance after “third party inspection” is of course also possible for these components.
Our Hartmann Kelly Valve enables a safe drilling and production operation.
Kelly valves are used as a safety valve in drilling rigs. The use of the kelly valve enables an interruption of the media flow inside the drill string. Depending on the conditions, we supply our kelly valves with different overall lengths, external and internal diameters as well as thread types. Manufacturing is done according to API specifications 7-1 and in compliance with IS0 9001:2015. Certification (Type Approval) by ABS and DNV is possible.
Innovative energy concept: deployment of hydrogen ball valves in the "WindGas Falkenhagen" power to gas plant.
The power to gas process enables electrical power from regenerative energies to be made storable in the form of chemical energy. In various pilot plants wind energy, for example, is converted into hydrogen by means of electrolysis. Particularly high demands are placed on the shut-off valves by the medium hydrogen when feeding into the gas grid. Hartmann Valves, supplier of ball valves and wellheads for more than 70 years, has the appropriate expertise in the area of gas storage engineering and valves for extreme conditions, for example in hydrogen applications. Absolute gas-tight ball valves which have a pure metallic sealing system are already in use in several power to gas plants. Produced from high grade materials and designed for the special requirements of hydrogen, they guarantee extreme reliability and a long service life.
With customer-specific designs, Hartmann wellheads are available for the safe storage of large quantities of energy.
In order to store future large quantities of energy for balancing production and consumption, various concepts are being pursued. In so doing, different media such as compressed air energy storage (CAES), hydrogen or synthetic natural gas are stored underground. Decades of experience from the crude oil, natural gas and chemical industries as well as collaboration in the first pilot projects makes Hartmann Valves a sought-after partner for the expansion of renewable energies and provides safe and controlled handling of the vast quantities of energy.
Based on the newest technical standards, adapted to the special requirements and in close coordination with the customers, the Hartmann wellheads are designed for this. Metal-to-metal sealing ball valves thereby guarantee a gas-tight and especially low maintenance shut-off.
Special valves, which have evolved for the demanding hydrogen medium, have been used in the petrochemical industry for many decades. With energy transition, hydrogen will be found increasingly in other fields of application – from electricity generation (such as power-to-gas), through transport (in natural gas grids or hydrogen pipelines), to processing and mobility.
The underground storage of hydrogen in salt caverns constitutes an environmentally friendly and safe solution for storing large amounts of energy to balance between power generation and demand.
The use of metallic sealing ball valves on the wellheads ensures superior leak-tightness, a long service life and low maintenance requirements.
More than 30 reference projects since 1978 speak for themselves: as interface between the borehole underground and the above-ground geothermal plants, Hartmann wellheads have been in maintenance-free deployment for years in the Munich Molasse basin, the Rhine graben as well as in France, Belgium, the Netherlands and Turkey, amongst others. Adapted to project-specific requirements and designed for the highest flow rates and temperatures, they provide maximum operational safety and plant availability.
The wellheads are, by default, fitted with gas-tight ball valves which have a metallic sealing between ball and seat ring thus guaranteeing extreme reliability and long service life. In contrast to gate valves, ball valves have the advantage that even with scaling deposits in the pipe they close securely and require significantly less maintenance. With high safety factor levels Hartmann ball valves are true workhorse valves which if required are provided with flushing connections, e.g. for acidification.
Hartmann wellheads with integrated ball valves are distinguished by their special robustness and long service life.
In the extraction of oil and gas a multitude of particles and concomitant materials are entrained in the medium flow. This places high demands on the shut-off valves. For more than 70 years Hartmann products, with their robust and individually tailored design, have provided the highest level of safety – even with dangerous and corrosive media such as sour gas, sour oil (H2S) and CO2. An experienced service team is available around the clock for assembly service, repairs and maintenance work.
In both conventional wellhead design and in solid block design, metal-to-metal sealing ball valves provide the highest level of safety.
Our API 6A conformant wellheads are fitted as standard with metal-to-metal sealing ball valves which are also gas-tight. In comparison to gate valves they offer a very high level of safety as they have a lower tendency towards blocking, are subject to less wear and don’t have to be filled with grease which can contaminate downstream plant parts. Thanks to the metallic sealing between ball and seat ring, Hartmann ball valves fulfil a leak rate of A or 0 and are especially robust and require only little maintenance. Additional safety is provided by a second barrier (DIB 2). Decisive for the long service life is an appropriate material selection as well as surface treatments and special coatings – against corrosion, for example. Hartmann wellheads are adapted to individual customer requirements as conventional or integrated designs.
This wellhead for sour gas production is equipped with a quick-closing valve with the appropriate actuator.
With the integral design the functions of several valves and wellhead components are brought together in one component. By this means, not only is the installed height minimised but by saving on flanged connections, safety is increased above all. Added to that, the installation time is reduced, corrosion-prone nuts and bolts are dispensed with and an absolutely perpendicular installation with uninterrupted diameter is a given. In the area of oil extraction, Hartmann ball valves are also suitable at high temperatures in the steam applications used to fluidise the oil. In this regard the viscosity is lowered by steam injection at high temperatures.
Clever concept: the Hartmann pig valve replaces complex launching and receiving stations.
Scrapers lend themselves to the cleaning of paraffin deposits or water condensate. Hartmann pig valves offer a space and cost saving alternative to complex pig launching stations. In addition to the conventional application as a shut-off valve, the pigging valve functions as a sending or receiving valve for pigs.The pig valve can furthermore be deployed for separating various products in a pipeline. This concept has two independent safety barriers when opening and requires no special tools. Hartmann pigging valves are deployed, amongst others, by well-known oil concerns as a global standard solution.
As a system supplier to the storage industry, Hartmann is involved in virtually all German oil and gas storage projects.
As early as the 70’s the underground storage capacity in Germany was massively extended for the national oil reserves. In oil storage, oil and saturated salt solution (brine) are alternated. With its high salt content, the brine is very corrosive and thus places high demands on wellhead materials.
Akin to crude oil storage, gas is also stored in subterranean reservoirs. These can be previously depleted reservoirs, aquifers or artificially produced cavities (caverns). Gas storage serves fundamentally to compensate for the varying seasonal demands. Cavern reservoirs in particular have large access cross sections and are stringently reliant on gas-tight components. Due to these demands, Hartmann has been able to assert itself as market leader for the equipping of gas reservoirs. Originating in Germany, the wellheads are also being deployed in many international projects in England, Denmark, the Netherlands, Portugal, Turkey and China.
Hartmann ball valves are integrated into the wellheads as a reliable shut-off or are deployed as high-performance valves in brine plants, compressor stations and gas refinement plants.
Hartmann wellheads with integrated ball valves are characterized by their special resistance and longevity.
In contrast to oil and gas extraction, storage necessitates considerably larger pipe cross sections. Conventional shut-off concepts such as gate valves are not up to these demands. Which is why our API 6A conformant wellheads are fitted as standard with metal-to-metal sealing ball valves which are also gas-tight. Compared to Gate Valves, they offer greater safety, as they are less prone to blocking, subject to less wear and need not be filled with grease, which could contaminate downstream equipment. Thanks to the purely metallic seal between ball and seat ring, the Hartmann ball valves fulfill a leak rate of A or 0 in all pressure stages and are particularly resistant and require little maintenance. Additional security is provided by a double barrier (DIB 2). Decisive for the long service life are an appropriate selection of materials as well as surface treatments and special coatings, for example against corrosion.
Adapted to individual customer requirements Wellheads are in classic design or available. In the latter case, the functions of several valves and wellhead components are combined in one component. This not only minimizes the height, but also increases safety by saving flange connections. In addition, the construction time is reduced, corrosion-prone bolts and nuts are eliminated and an absolutely vertical structure with undisturbed drift diameter is given.
This x-mas treee in solid block design has the latest wellhead technology and offers increased safety due to the reduction of interfaces.
Many of the existing storage plants undergo a general overhaul after years of operation. The borehole completion is replaced and in the process, the wellheads are brought up to the latest state of technology. In collaboration with our customers we have, for example, been able to significantly increase the safety and integrity of the reservoirs in the past years. Hence strain gauges are used for monitoring the pipes and individual components are combined in blocks (block design) whereby interfaces are reduced. In addition to the metallic sealing he ball valves were also fitted with a second barrier (DIB 2). Remaining flange connections have also been given a second barrier and partial metallic sealing. With these innovative concepts, which the conventional oil and gas industries don’t offer, Hartmann Valves are making a sustainable contribution to long-term safety in reservoir storage. At the same time, professional consultation and support during all project phases are for us a given. The experienced Hartmann service team is available around the clock for installation and maintenance work.
In customized design Hartmann wellheads are available for the safe storage of large amounts of energy.
For the continued expansion of renewable energies a storage potential is necessary for enormously large quantities of energy. This energy can and is being stored in underground caverns. In this regard compressed air energy storage (CAES), with components from Hartmann, has been in existence for several decades and a further step (pilot projects have been or are already being implemented) is the storage of hydrogen and synthetic natural gas storage. In the area of hydrogen storage we are able to fall back on the many years of experience gathered from supplying to refineries all over the world. Flexibility and cross-industry experience has meant that the company Hartmann has also established itself as a good partner in the area of these special applications. Hence Hartmann has also equipped the first European storage cavern for helium.
This FDA compliant hydrogen ball valve has a metal-to-metal sealing and guarantees a leak rate of A or 0
The generation of products in chemical processes presents high level demands on the reliability of the plant components. The areas of application of high performance valves are varied: designed to individual customer requirements they are suitable for temperatures of -200 to +550 °C, pressure stages up to 700 bar and up to 200,000 cycles per year. Hartmann valves are already in successful deployment for the following, in part aggressive media: crude oil, natural gas, acid gas, syngas, oxygen, hydrogen, helium, steam, thermal water, coal dust, slurry, slag & ashes, polymers, cellulose as well as abrasive and degreasing media.
The valves can be flexibly combined with electric, pneumatic or hydraulic actuator technology.
Double ball valve for double safety: with the twin ball valve the safety in the structural length of standard valvework is increased by a factor of 4.
The high leak-tightness and durability of the Hartmann special ball valves is achieved by means of a metallic sealing between ball and seat ring. This sealing system is gas-tight and also fulfils a leak rate of A or 0 even with high cycle operations. Even in the presence of contamination it is considerably more robust with low maintenance than soft sealing systems. A further decisive factor is the appropriate material selection as well as surface treatments and special coatings. Thanks to the longer maintenance intervals, substantial time and cost savings over the entire service life of a plant can be realised. Additional safety is provided by special design features and safety orientated functions such as double isolation and bleed (DIB), two additional independent barriers or double block and bleed (DBB), which enable testing in the pipeline. To increase the safety in existing plants with minimal outlay, the twin ball valve offers a compact and economical alternative to the deployment of multiple valves. These consist of two ball valves in one housing which can be equipped with two independent barriers if required.
Our multi-way valves are also individually developed to customer requirements and are fitted with a metal-to-metal sealing system.
Multi-way valves lend themselves where switching over between different lines has to take place. An example of a typical application is the switching over between two filter systems. This makes continuous operation possible by which one filter remains in use while the second is cleaned, replaced or regenerated. The combination and mechanical coupling ensures that several valves are switched at precisely the same moment. The valves are furthermore used to switch over between different media, e.g. fuels on turbines. By means of the trunnion mounted design, the ball is centered in the middle of the valve even under asymmetric loads. The spring loaded sealing rings provide a reliable seal in all pressure situations. The different angle between the flanges and ball bores in L, T or X execution results in a variety of combinations.
In power plants with particularly high demands, reliable high performance valves provide maximum safety.
Hartmann ball valves are deployed in many different power plants and thus also under the most varying conditions. Besides the applications listed below for hydropower, steam and gas turbines, ball valves for example are also being developed for the reverse transformation of electrical into chemically bonded energy in the form of hydrogen (see renewable energies).
Wellhead equipment for high demands
Durable wellheads with pure metallic sealing ball valves provide a high level of flexibility and availability in the Jemgum gas cavern storage.
With the new build of the storage plant in the Lower Saxony town of Jemgum, EWE Gasspeicher GmbH commissioned Hartmann Valves GmbH to supply all brine and gas wellheads, diverse special ball valves and the associated assembly and maintenance service. The „Hartmann concept“, i.e. the use of pure metallic sealing ball valves as wellhead shut-off valves which are absolutely gas-tight even in large nominal bores, had already proven itself in the equipping of other storage plants as highly durable and virtually maintenance-free.
Reliable isolation for Wolfersberg Gas Storage
Unique Twin Ball Valves designed for space limitation.
Reliable isolation for Wolfersberg Gas Storage – Unique Twin Ball Valves designed for space limitation
Since the upper Bavarian gas storage facility of DEA was established in 1973 about 800 Hartmann ball valves have been installed in the various operations. The depleted gas reservoir with depths of 2,900 to 3,000 metre located southeast of Munich is the deepest gas storage in Europe. Besides the 10 wells for injection and production, facilities are run for the compression, pressure reduction, drying and temperature control of the gas. A very high safety level as well as plant availability are critical. When old shut-off valves had to be replaced, Hartmann designed extra compact Twin Ball Valves, which are bubble-tight and solve problems of space limitation.
Refit in record time
Optimal planned maintenance of safety ball valves enables recommissioning on schedule
Optimal planned maintenance of safety ball valves enables recommissioning on schedule
The natural gas field Völkersen located in the north-western part of Lower Saxony and operated by DEA is one of the most productive in Germany. When operating, as well as during service and preventative maintenance of the surface facilities and the production wells conducted by DEA Niedersachsen, safety has top priority. All components of the plant have to fulfill the highest technical requirements at any time.
In the course of regular 5 yearly maintenance of the Central Gas Drying Plant about 20 ball valves manufactured by Hartmann Valves were inspected and overhauled in September 2016. Thanks to early planning and close cooperation all valves could be reconditioned in a short period and taken back into operation right on schedule.
With zero leakage, a 50 year lifetime and exceptional temperature and pressure ratings.
With zero leakage, a 50 year lifetime and exceptional temperature and pressure ratings, Hartmann ball valves have significantly reduced maintenance demands on the Nord Stream gas pipeline.
The Nord Stream pipeline transports natural gas from Russia to the EU internal market, with capacity to deliver up to 55 bcm per year, providing enough power for up to 26 million homes.
Nord Stream wanted to upgrade the pipeline’s valve system, to reduce maintenance demands and ensure reliable sealing on this important route.
Nord Stream selected Fahlke Control Systems and Hartmann Valves to deliver a new system, complete with actuator, control unit and ball valves, which could meet Nord Stream’s high safety, temperature, pressure and corrosion standards and deliver a 50+ year operational life.

The ammonia factory is worldwide unique: both gasification lines can either be run on natural gas or oil. One component are the 5“ shut-off ball valves from Hartmann Valves. These are especially designed for the challenging combination of pure oxygen, steam and high temperatures. All customer demands have been fulfilled above-average. The energy efficient production secured the economic future of the facility.
Metal to metal sealing ball valves for innovative hydrogen project.
Maximum operational safety and availability of Power-to-Gas-Plant: E.ON Gas Storage counts on true metal sealing ball valves
In 2013 Uniper Energy Storage GmbH (UST) brought the power-to-gas plant “WindGas Falkenhagen” successfully on stream. With this project Uniper has been demonstrating, as one of the first companies worldwide, a way how renewable energy can be stored in the natural gas grid in order to make production independent from consumption. For the pilot plant in Falkenhagen (Germany) Hartmann Valves supplied 24 true metal to metal sealing ball valves, designed to meet the excessive demands for service associated with pure hydrogen whilst ensuring maximum safety.
Well completion for the deepest and most productive German well.
Consultant gec-co counts on Hartmann Valves & Wellheads for Well Completion
Geothermal energy is a perfect example for renewables. It is resource-saving, produces no pollution and the availability is almost unlimited. The city of Traunreut is an ideal location for geothermal energy since it is situated in the Bavarian Molasse Basin. With two wells drilled successful and the installation of the district heating transmission station, Traunreut feeds geothermal energy in the municipal network. 3000 housing units as well as industrial clients are supplied this way. The geothermal power plant will presumably produce climate-neutral electricity by 2016.
Successful changeover: The Xmas tree with ball valves
Within the scope of overhauling several Xmas trees for gas production, a completely new design of construction was decided on: In the place of Xmas trees with gate valves, solid block Xmas trees with integrated ball valves have already been in operation at several North German locations since 2018. This concept unites the preferences for a compact design with the advantages of gas-tight ball valves over gate valves – at high and in particular also low pressures. Also decisive was the positive experiences with safety ball valves as complementing quick-closing valves in the above-ground installations. The innovative design, which was developed in close collaboration between Hartmann Valves and the operator, provides not only for increased safety and simple operability but also for significantly reduced maintenance requirements.
