Frequently Ask Questions
A Pneumatic Cryogenic Ball Valve is designed for very low-temperature service and uses compressed air to automatically rotate the ball for opening and closing.
The extended bonnet keeps the stem packing and sealing area away from extreme cryogenic temperatures, helping maintain reliable sealing.
A double-acting actuator uses air for both opening and closing, while a spring-return actuator uses air in one direction and springs for the return stroke.
Alis Valves manufactures and supplies Pneumatic Cryogenic Ball Valves for automated isolation in LNG, industrial gas, and other demanding low-temperature applications.
Compressed air operates the pneumatic rotary actuator, which rotates the ball approximately 90° to open or close the valve.
Depending on the valve design and materials, it can be suitable for temperatures down to approximately -196°C.
Fail-safe operation moves the valve to a predetermined safe position when air supply is lost. Common configurations are Fail Open and Fail Close.
