Cryogenic Pneumatic Shut Off Valve Flange Connection For LNG/LO2/LN2/LAr

Cryogenic Emergency shut-off valve is a kind of valve of the actuator in the automation system. It consists of a multi-spring pneumatic diaphragm actuator or a floating piston actuator and a regulating valve. It receives signals from the regulating instrument and controls the cut-off, connection or switching of the fluid in the process pipeline. . It has the characteristics of simple structure, sensitive response and reliable movement. Can be widely used in petroleum, chemical, metallurgical and other industrial production sectors. The air source of the pneumatic shut-off valve requires filtered compressed air, and the medium flowing through the valve body should be a liquid and gas without impurities and particles.
