Product Description

The pneumatic diaphragm direct single seat regulating valve adopts a top guide structure and is equipped with a multi spring actuator. It has the advantages of compact structure, light weight, sensitive action, S-streamlined filling channel, small pressure drop loss, large valve capacity, accurate flow characteristics, and convenient disassembly and assembly. Widely used for precise control of gases, liquids, and other media, process parameters such as pressure, flow rate, temperature, and liquid level are maintained at given values. Especially suitable for working situations where the pressure difference between the front and rear of the valve is small and allows for small leakage.
Parameters of fluorine lined regulating valve:
Valve body and cover: HT200, ZG230-450, ZG1Cr18Ni9Ti
Valve core and valve seat: 1Cr18Ni9Ti, Stellite alloy surfacing welding
Soft sealing valve core: reinforced polytetrafluoroethylene
Filler: PTFE, flexible graphite
