Cryogenic Control Valve

Cryogenic flow control valveis suitable for the adjustment of the medium (such as liquid oxygen, liquid nitrogen, etc.) under the low temperature and strong state of -60～-250℃. To ensure the accuracy of adjustment, a positioner must be used. Pneumatic low temperature is composed of a pneumatic membrane actuator and low temperature resistant single and double seat valve. The signal pressure from the regulator is input into the air chamber of the pneumatic membrane actuator to generate thrust, and the cryogenic flow control valve core is driven by the connecting rod. The change of the valve core position in valve control systems changes the flow cross-sectional area of the cryogenic control valveto realize the adjustment of the medium flow.
