ZJHP regulating valve
ZJHP regulating valve
The ZJHP pneumatic control valve produced by Shanghai Yang Yi Valve Co., Ltd. adopts the top guide structure and is equipped with multi spring actuator. The utility model has the advantages of compact structure, light weight, sensitive action, fluid channel S streamline, small pressure drop loss, large valve capacity, accurate flow characteristics, convenient disassembly and assembly, etc..
It is widely used in the accurate control of gas, liquid and other media process parameters, the pressure, flow, temperature, liquid level to maintain a given value. It is especially suitable for occasions where the leakage is small and the pressure difference between front and rear valves is small.
This series of products have standard type, cut off type, bellows seal type, jacket insulation type and many other varieties. Nominal pressure levels of products are PN16, 40, 64; nominal diameter range DN20~300. Applicable fluid temperature range from -200 to 560 degrees celsius. The leakage standard has level IV or class VI, and the flow characteristics are linear or equal. A variety of varieties and specifications to choose from.
