Pneumatic Single Seat Control Valve

Pneumatic Single Seat Control Valve
ZJHP fine small pneumatic film single seat regulating valve adopts top guide structure, with multiple spring actuator. It has the advantages of compact structure, light weight, sensitive action, s-streamline fluid channel, small pressure drop loss, large valve capacity, accurate flow characteristics, convenient disassembly and assembly. Widely used in precise control of gas, liquid and other medium process parameters such as pressure, flow, liquid level to maintain a given value. It is especially suitable for small leakage and small pressure difference before and after the valve. The nominal pressure levels of products are PN16, 40, 64; Nominal diameter range DN20 ~ 400. Suitable for liquid temperature from -200℃ to +560°C range of various grades. The leakage standards are grade iv or vi, and the flow characteristics are linear or equal percentage. A variety of character specifications to choose from.
