Cryogenic Pneumatic Ball Valves: Overview & Technical Parameters

The Cryogenic Pneumatic Ball Valve consists of a Forged Steel Extended Shaft Cryogenic Ball Valve and a Pneumatic Actuator. It drives the piston of the actuator to rotate left and right through an air supply pressure of 0.4~0.7MPa to realize opening and closing actions. An explosion-proof solenoid valve, signal feedback (limit switch), air filter regulator, and handwheel device can be added to achieve integrated automatic control.
