Product Description

Pneumatic fine small film regulating valve overview
Pneumatic fine small film regulating valve is divided into: SZJHP pneumatic fine small film single seat regulator, SZJHM pneumatic fine small film sleeve regulating valve. SZJHN pneumatic fine small film two-seat regulating valve adopts top guide structure, with multi-spring actuator. It has the advantages of compact structure, light weight, sensitive action, streamlined fluid channel, small pressure drop loss, large valve capacity, accurate flow characteristics, convenient disassembly and assembly. Widely used in the accurate control of gas, liquid and other media process parameters such as pressure, flow rate, liquid level to keep in the given value. Especially suitable for allowing small leakage and the valve front and rear pressure difference is not large in the workplace.
Pneumatic fine small film regulating valve products have a variety of varieties, such as standard type, regulation cut type, bellows seal type, jacket insulation type. Nominal pressure grade of products are PN16, 40, 64; Nominal diameter range DN20 ~ 300. Suitable for liquid temperature range from -200ºC to +560ºC in a variety of grades. The leakage standard is4grade or 5grade, the flow characteristic is linear or equal percentage. A wide variety of character specifications are available
