The ZJHP pneumatic single-seat regulating valve is composed of a pneumatic multi-spring diaphragm actuator and a low-resistance single-seat valve. The new actuator is low in height, light in weight, and easy to calibrate. The new valve body has a compact structure, unobstructed flow channel, and a large flow coefficient.
This product has stable operation, reliable action characteristics, small valve seat leakage, precise flow characteristics, and a wide adjustable range. It will surely achieve high-quality control effects in a wide range of applications with its unique advantages.
