ZJHP/M-GW pneumatic high temperature control valve consists of a multi-spring pneumatic diaphragm actuator and a low flow resistance high temperature regulator valve body. The multi-spring actuator is low in height, light in weight and easy to install. The valve body runner of pneumatic high temperature control valve is S streamlined, which has the advantages of compact structure, light weight, sensitive action, small pressure drop loss, large valve capacity, accurate flow characteristics and convenient maintenance. It can be used in harsh working conditions. Pneumatic high temperature control valve It is equipped with an electric-gas valve positioning or a pneumatic valve positioner to achieve automatic adjustment control of the fluid medium in the process line. Pneumatic high temperature control valve is widely used in process parameters for precise control of gases, liquids, vapors, etc. For example, it can allow parameters such as pressure, flow, temperature, and liquid level to be maintained at a given value. Pneumatic high temperature control valve is especially suitable for occasions where the leakage is small, the pressure drop of the control valve is small and the temperature is high.
