Pneumatic high temperature control valve is composed of multi-spring pneumatic film actuator (or piston pneumatic actuator) and low flow resistance control valve body. The multi-spring actuator is low in height, light in weight and simple in equipment. The flow passage of the pneumatic film high temperature control valve body is S-streamlined. It has the advantages of compact structure, light weight, sensitive action, small pressure drop loss, large valve capacity, accurate flow characteristics and convenient maintenance. The pneumatic high temperature control valve regulator adopts balanced plug structure, which has good valve stability, less vibration and low noise. Temperature sensitivity is low. The pneumatic film high temperature control valve is especially suitable for occasions where the leakage requirement is not high and the temperature is high.
