Product Details
High temperature pneumatic control valveIt is composed of a multi spring pneumatic diaphragm actuator (or piston type pneumatic actuator) and a low flow resistance regulating valve body. The multi spring actuator has low height, light weight, and easy equipment. The flow channel of the pneumatic thin film high-temperature regulating valve body is S-shaped, which has the advantages of compact structure, light weight, sensitive action, small pressure drop loss, large valve capacity, accurate flow characteristics, and easy maintenance. The regulating mechanism of the pneumatic high-temperature regulating valve adopts a balanced valve plug structure, which has good valve stability, is not easy to vibrate, low noise, and low sensitivity to temperature. Pneumatic thin film high-temperature regulating valve is particularly suitable for occasions with low leakage requirements and high temperatures.
