CF8 CF8M Electric Pneumatic Driven Cryogenic Fluid Regulating And Control Valve
Product introduction:
L2023044 pneumatic diaphragm type cryogenic regulating valve is to drive the opening and closing of the valve through the pneumatic diaphragm actuator, achieving the regulation of low-temperature fluid. Specifically, when the input air pressure acts on the pneumatic diaphragm actuator, the diaphragm produces displacement, driving the valve stem to move, thereby changing the opening degree of the valve port and regulating the flow rate and pressure of the fluid.
Pneumatic diaphragm type cryogenic regulating valve is a valve widely used in the field of industrial control, mainly used to regulate the flow and pressure of low-temperature fluids (such as liquid oxygen, liquid ammonia, etc.). This regulating valve adopts a pneumatic thin film actuator, which has the advantages of simple structure, stable regulating performance, and convenient operation. It is one of the important equipment for achieving precise control of low-temperature fluids.
