Pneumatic Cast Steel Gate Valve Quick Cut-off Switch Regulating Valve Z641h-16c DN200

 Products Description https://bodavalve.en.made-in-china.com Pneumatic gate valves are driven by compressed air. When the gate valve is closed, the sealing surface can only rely on medium pressure to seal, that is, the sealing surface of the gate plate can be pressed towards the valve seat on the other side to ensure the sealing surface is sealed, which is self sealing. Most gate valves use forced sealing, which means that when the valve is closed, external force is used to forcefully press the gate plate towards the valve seat to ensure the sealing surface is sealed.Pneumatic gate valve: A valve that is driven by compressed air.The practice of only specifying specifications, categories, and working pressure when purchasing pneumatic valves to meet procurement requirements is not perfect in the current market economy environment. Because pneumatic valve manufacturers, in order to compete for their products, have carried out different innovations under the unified design concept of pneumatic valves, forming their own enterprise standards and product personalities. Therefore, it is necessary to provide detailed technical requirements and coordinate with the manufacturer to reach a consensus when purchasing pneumatic valves, as an attachment to the pneumatic valve procurement contract.name descriptionmaterial qualitystainless steelpressure0.6mpa~40mpacaliberDN40~DN450temperature-29°C ~425°Cmediumwater  ,Steam ,oilConnection methodflangeDriving methodmanual,electric  Detailed photos   Pneumatic gate valves are driven by compressed air.
