Overview of pneumatic double seat regulating valve

Zjhn pneumatic double seat regulating valve adopts double number guiding structure and is equipped with multi spring actuator. It has the advantages of compact structure, light weight, sensitive action, large valve capacity, accurate flow characteristics, convenient disassembly and assembly, etc. Pneumatic double seat regulating valve is widely used to accurately control the process parameters of gas, liquid, steam and other media, such as pressure, flow, temperature and liquid level, to maintain at the given value. It is especially suitable for medium occasions with large differential pressure, large allowable leakage and not very clean.

There are many kinds of pneumatic double seat regulating valves, such as standard type, bellows sealing type, jacket insulation type and so on. The nominal pressure grades of products are PN16, 40 and 64; The diameter range of valve body is DN25 ~ 400. Applicable fluid temperature ranges from -250 ℃ to +560 ℃. The leakage standard is level III and level IV. The flow characteristic is linear or percentage. A variety of varieties and specifications are available.
