Fine small pneumatic diaphragm valve is divided into: SZJHP fine small pneumatic membrane single seat control valve, SZJHM pneumatic diaphragm control valve sleeve.SZJHN fine small pneumatic fine small film double seat control valve driven by the top structure, equipped with multi spring actuator. Has the advantages of compact structure, light weight, flexible action, fluid channel was streamlined, S has the advantages of small pressure drop loss, valve capacity, accurate flow characteristics, convenient disassembly and assembly etc.. Widely used in the precise control of the gas and liquid medium parameters such as pressure, flow, liquid level is maintained at a given value. Suitable for small leakage and allow the valve before and after the pressure.

 Fine small pneumatic membrane valve products are the standard type, regulating off type, bellows seal type, jacket type insulation and other varieties. Nominal grade products are PN16, 40, 64; nominal diameter range of DN20 ~ 300. Application of liquid temperature from -200 DEG C to +560 temperature range of various grades. Leakage standards of grade IV or VI, flow characteristics such as linear or
Percentage。 The character of a variety of specifications available.
