Cryogenic Control Valve

Cryogenic flow control valve is 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
valve to realize the adjustment of the medium flow.
