      • Scraper valve Type HM

      • HARTMANN VALVES pigging ball valves of the HM series combine the advantages of the HARTMANN VALVES AST series, and in addition to classic applications function as shut-off valves for pigging insertion or removal valves. The simple, secure, and fast insertion and removal of pigs takes place through an interlock that is integrated on the side of the pigging ball valve and that is locked and secured through a bayonet system.
        HARTMANN VALVES pigging ball valve can be obtained as a scraper valve for cleaning operations (type HMR), as a scraper valve for cleaning operations, but in addition with a bypass in the closed position for applications during which the medium flow is not to be interrupted completely (type HMB)), and as a scraper valve for separating different products in a pipe line (type HMS).

        In the standard version HARTMANN VALVES pigging ball valves are designed for a maximum pig length of 1.4 x nominal diameter of the pipe line. Upon request, we are pleased to offer you special constructions for spherical pigs or cylindrical pigs longer than 1.1 to 1.4 x diameter up to a maximum of 2.0 x diameter.

        The simple handling of the HARTMANN VALVES pigging ball valves speaks for itself: For the insertion or removal of the pig the ball is rotated by 90°, meaning it is rotated into the closed position. Prior to the opening of the interlock the housing interior is depressurized via a release valve, then the bayonet catch is unlocked and opened with a left turn. The pig can now be inserted or removed through the interlock.
        The advantages of the HARTMANN VALVES ball valves are primarily: Simpler operation, secure handing, reduced footprint, lower investment costs in comparison to traditional pigging interlocks.

      • Industries

      • Challenging Applications – We support our customers with industry specific expertise, innovative solution concepts and reliable products.
          • Oil / gas extraction

          • The extraction of oil and gas frequently occurs under tough operating conditions. Adverse environmental effects and in part aggressive and contaminated media with a multitude of attendant materials represent special challenges regarding the reliability of the plants. HARTMANN VALVES Products offer the highest degree of safety, with long service life, in this area also with their robust design and a materials’ selection that is tailored to each application case.
          • Storage technology

          • A significant application area for well heads and valves by Hartmann Valves GmbH is the surface area equipment of underground gas stores. Similar to crude oil storage, natural gas is stored in geological formations that are suitable for this purpose.

            Storage provides assurance regarding the bridging of possible supply shortages, as well as seasonal demand equalization.
            The challenge of storing the gas medium under high pressure has had the effect of the Hartmann Valves company becoming one of the primary suppliers for storage projects over the last few years.

            Over the course of many millions of years enormous salt deposits formed in the northwest of Germany. The available salt is seal tight, as compared to hydrocarbons, and it is preferably used for storage for that reason. To establish a sufficiently large hollow space, the so-called cavern, water is injected via a bore hole. The salt is dissolved by the water, and then extracted. This process can take several years. Once the desired storage volume is reached, the cavern is equipped for the first filling and the subsequent gas storage.

          • Petrochemistry

          • In the petrochemistry area products are manufactured in chemical processes from crude oil and natural gas. In that context high demands are placed on the reliability of the plant components. At times aggressive media, high operating temperatures and demanding switching cycles, and highly degreasing processes present special challenges for shut-off installations.

            HARTMANN VALVES ball valves have excelled in this application area also. Starting with the selection of materials, to special coatings, to high-cycle switching gears, the valves are specially equipped for the requirements of the deployment area. Please contact us – and profit from our experience.
          • Geothermie

          • As manufacturers of high performance ball valves and wellheads Hartmann Valves successfully realized numerous geothermal projects in the Bavarian Molasse Basin, the Upper Rhine Graben and other countries. Based on the high requirements of deep geothermal applications our equipment is designed for a long service life, meets highest safety standards and guarantees a maximum of operational availability. Examples show that first geothermal components are installed 30 years ago and operate nearly maintenance-free. Our products are designed to the individual requirements of our customers and are developed, manufactured and assembled in Germany (Celle). The wellheads are usually equipped with metal-to-metal sealing ball valves.
          • Renewable Energy

          • Example: Ball valves for Power-to-gas plant

            Thanks to their special technical characteristics, high performance valves of Hartmann Valves GmbH are often chosen for new, highly demanding application areas, such as power-to-gas as innovative renewable energy. Power-to-gas is a process to convert electricity produced by renewables into chemical energy. As one of the first companies worldwide E.ON Gas Storage GmbH demonstrates in Falkenhagen, Germany a way how renewable energy can be stored in the natural gas grid in order to make production independent from consumption. In the demonstration project electricity and water are converted via electrolysis in up to 360 Nm3/h hydrogen which is then fed into the gas grid. For the power-to-gas-plant „WindGas Falkenhagen“ E.ON Gas Storage GmbH chose Hartmann shut-off valves approved for pure hydrogen service and designed for tightness over a long operational period. These true metal sealing ball valves meeting these excessive demands. Since commissioning in 2013 they successfully help assuring maximum safety and plant availability.
          • Power plant technology

          • The diversity of the different applications in conventional power plants likewise require different solutions, which is why it is one of our interest areas.

            In safety-relevant applications, functional reliability and longevity are a major challenge for a manufacturer. These tasks can only be handled with experience and superbly trained personnel.
            e.g. ball valves in the primary circulation of a turbine, in fuel lines, exhaust gas lines at high temperatures etc..
            It is the combination of high demands and safety standards, as in other application areas, that guide customers to us.
