The ZJHN pneumatic membrane double seat regulating valve adopts a double guide structure and is equipped with multiple spring recruit agencies. It has the advantages of compact structure, light weight, sensitive action, large valve capacity, accurate flow characteristics, easy disassembly and assembly. It is widely used in precise control of gas, liquid, steam and other media process parameters such as pressure, flow, temperature, liquid level to maintain at a given value. It is especially suitable for occasions with larger pressure difference and larger leakage and is not very clean. This series of products has standard type, bellows seal type, jacket insulation type and so on. The nominal pressure level of products is PN16, 40 and 64, and the caliber of valve body ranges from DN25 to 400. Suitable fluid temperature ranges from -250 to +560 degrees. The standard of leakage is grade III and IV. The flow characteristic is linear or percentage. Various varieties and specifications are available.
