        • Applications

            • Alternative Energies - Biomass

            • There are many different applications throughout a biomass plant that require high performance equipment to meet plant standards. Due to the variation of suitable raw materials that can be used to produce alternative energy, knife gate valves have to be able to shut off against many organic materials such as food and waste, manure, raw sewage and different kinds of agricultural waste.
              Wey Knife Gate Valves have been in service successfully in hundredths of biomass plants for more than a decade. Due to their unique design features, Wey Knife Gate Valves ensure bubble tight bi-directional shut off with reliable and long service life, the perfect solution for every biomass plant.
            • Cement Industry

            • Wey‘s Knife Gate Valve design makes it a desired valve for the manufacturing of cement. Cement is manufactured through a closely controlled chemical combination of calcium, silicon, aluminum, iron and other ingredients. Common materials used to manufacture cement include limestone, shells and chalk or marl combined with shale, clay, slate, blast furnace slag, silica sand and iron ore. Conventional knife gate valves are usually not suitable for cement mixing. Leakage is very objectionable. Bi-directional bubble tight shut off is a requirement. Wey’s unique transverse seal with scraper blade design eliminates leakage to atmosphere and can be repacked in service and under full rated pressure without down time or rebuild.
            • Chemical and Petrochemical Industry

            • Wey Knife Gate Valves have been in service successfully in various chemical and petrochemical applications for decades. The unique Wey design ensures bubble tight bi-directional shut off with reliable and long service life. These valves ensure that hazardous material such as Sulfur Dioxide, Acids and others are not released to the atmosphere. Ordinary knife gate valves are usually not suitable for chemical or petrochemical applications. Leakage is very objectionable. Bi-directional bubble tight shut off is a requirement. With our design and the material of construction compatible with the process we can dramatically increase valve service life.
            • Flood Protection

            • We offer a comprehensive range of water management and flood prevention products. Our designs are independent of external energy and environmentally friendly, not least due to their exceptionally economic operation. Our wide range of products covers throttling devices, rinsing plants, separators, weirs, products for sewage technology, fittings and products for control technology and sewage management.
            • Food & Beverage Industry

            • The requirements for knife gate valves in the food and beverage industry are high. High cycling capabilities, zero contamination and no jamming are usually a must. Challenges that can be resolved by using Wey Knife Gate Valves. In recent years we have successfully introduced Wey Knife Gate Valves in special applications like cocoa powder, potato starch, dairy products and sugar production. It is hard to tell how many more applications are out there for us to resolve with our Wey Knife Gate Valve. No matter what, the Wey team is already looking forward to the next challenges.
            • Infrastructure

            • The right solution for all infrastructural needs: The Wey Water Control Gate range is so broadly conceived and flexible, that it can be adapted for all situations. Thanks to technical finesse, quality and diversity in service, our products have become the first choice in water and wastewater treatment, for collecting and retention basins, as well as for channel and pit construction. Also in focus the range of products for flood prevention and for water management. Self­-energized designs are friendly to the environment and most economical.
            • Mining - Tailings

            • One of the most unpleasant byproducts of all mining applications are open pit mine tailings. Worldwide, the storage and handling of tailings is a major environmental issue. Most open pit mines transport their tailings to wet storage areas of pits or ponds. These ponds can be enormous in scale since the actual mineral extraction is typically only ounces or pounds for every ton of earthen rock moved. Mine tailings lines carry heavy slurries often with toxic chemicals. The knife gate valves in this application must have bubble tight shut-off and extended service life in extreme conditions. Most mine tailings are very abrasive and are traveling at high velocities.
              The Wey Knife Gate Valve is the perfect solution for this application where absolute zero leakage and long service life is critical in both transportation and isolation of mine tailings.
            • Oil & Gas Industry

            • Wey Knife Gate valves have been use by the Oil and Gas industry for many decades and as such we developed a comprehensive range of suitable and qualified products for challenging applications in this industry.
              Whether for onshore or offshore oil and gas applications, the unique Wey design ensures bubble tight bi-directional shut off with reliable and long service life in the toughest process conditions.
            • Power Generation

            • Wey Knife Gate Valves are designed specifically for on/off pipeline isolation services in hydraulic conveying applications, such as fly ash, bottom ash, ash slurry, scrubber and water supply systems in Coal Fired Power Plants. With thousands of installations worldwide, Wey Knife Gate Valves have delivered exceptional performance with its rugged and easy to maintain design.
            • Pulp & Paper Industry

            • Wey Knife Gate Valves are the ideal solution for the pulp and paper industry. From the cyclone separation of heavy solids from the wood, to high density stock and chemical separation of wood fibers in the pulp mill, to handling and cleaning the wood fiber in the power house, recausticizing and bleach plants, to the final blend of wood fiber into sheets of paper at the paper machine the Wey Knife Gate Valve is the desired valve due to its key design features like innovative seat design, superior packing system and unique body and gate design.
            • Water Treatment

            • Wey Knife Gate Valves have been used in the municipal sewage treatment market for nearly fifty years. The valve incorporates unique design features that overcome typical problems found in other knife gate valve designs. Today, the Wey Knife Gate Valve has spread throughout the industry in all of North America, Europe and other parts of the world where the original valve installations continue to perform successfully.
