- KPM- pneumatic high temperature control valve
- Category：Pneumatic control valve
product manual
Pneumatic high temperature control valve, a spring pneumatic diaphragm actuator (or piston pneumatic actuator) and low flow resistance regulating valve, multi spring actuator of low height, light weight, simple equipment. Pneumatic film high temperature regulating valve flow channel was streamlined S, has the advantages of compact structure, light weight, flexible action, small pressure drop loss, valve capacity, flow characteristics of precision, convenient maintenance, pneumatic high temperature control valve regulating mechanism adopts balanced valve plug valve structure, has good stability, not easy to vibration, low noise the temperature sensitivity, small. Pneumatic film high temperature control valve is especially suitable for leakage requirements is not high, high temperature.
