Electric Cryogenic Ball Valve

ALIS Valves offers Electric Cryogenic Ball Valves for industrial applications requiring reliable flow isolation and automated operation at extremely low temperatures. These valves feature a spherical ball with a central bore that rotates to open or close the flow passage, providing dependable on-off control for compatible cryogenic media. The valve design can incorporate an extended bonnet or stem arrangement to help keep the stem packing and actuator away from the coldest process zone, reducing the risk of excessive cooling at temperature-sensitive components. Suitable body, ball, seat and sealing materials are selected according to the cryogenic temperature range and process media. An electric actuator enables remote operation and integration with programmable logic controllers (PLCs), distributed control systems (DCS) and other industrial automation platforms. The complete valve assembly must be specifically designed and rated for the intended cryogenic service.

Electric Cryogenic Ball Valves are used in LNG facilities, industrial gas plants, liquid nitrogen and liquid oxygen systems, cryogenic storage tanks, gas processing installations and other low-temperature process applications. Depending on the specified design and material compatibility, they can be selected for suitable cryogenic liquids and gases within their rated operating limits. Important selection factors include minimum operating temperature, working pressure, valve size, process media, body and seat materials, stem extension requirements, leakage performance and actuator specifications. Buyers should also consider thermal contraction, seat sealing at low temperatures, electrical supply, actuator torque, operating time and enclosure protection. For oxygen service, material cleanliness and compatibility requirements must be verified, while LNG and other cryogenic applications may require compliance with relevant industry standards. Selecting a properly engineered valve and electric actuator combination helps support reliable isolation, safe automated operation and consistent performance under specified cryogenic conditions.
