Pneumatic diaphragm type Angle type ZJHS single-seat regulating coefficient of pneumatic valve technology

ZJHS fine small single-seat regulating pneumatic valve adopts pneumatic diaphragm Angle type at the top of the guide structure, with many spring actuators. With compact structure, light weight, action quick, fluid channels in an s-shaped streamlined, small pressure drop loss, large capacity of pneumatic valve, precise flow characteristic, convenient tear open outfit. Widely used in the precise control of gas, liquid and other medium parameters such as pressure, flow rate, temperature and liquid level in a given value. Particularly applicable to allow small leakage, pressure difference before and after pneumatic valve is high viscosity, containing suspended and the adjustment of the granular material fluid, can avoid coking, jams, facilitate the net with the occasion of the cleaning.
