Pneumatic Single-Seat Globe Control Valve (GAZJHP)
1. Pneumatic Single-Seat Globe Control Valve (GAZJHP) :
This product is composed of the pneumatic multi-springs, pneumatic actuator and the low flow resistance sleeve. This valve uses the balanced valve core, the unbalanced force is small, the permission pressure differential is big, and operation is steady. Compared with the ordinary single and double seat-regulating valve, it has low noise, simple structure and convenient assembling and dismantling characteristics.
Its valve shape is small, the body is light, the performance is good, and the capacity is big. So it's the new type general regulating valve product. It is suitable for the common fluid medium and techniques condition industrial control system.
The working temperature for normal Structure can be up to 250 Deg C. If the working temperature is higher than 250 Deg C, then Heat Radiator should be used. And trim should be done heat treatment.
