2-Piece Cryogenic Ball Valve

ALIS Valves offers 2-Piece Cryogenic Ball Valves for industrial applications requiring reliable flow isolation and dependable operation at extremely low temperatures. These valves feature a two-piece body construction consisting of a main body and an end connection, designed to provide a secure pressure-containing assembly for compatible cryogenic media. The spherical ball contains a central bore that rotates to open or close the flow passage, enabling efficient on-off control. The valve is engineered with suitable low-temperature body materials, ball and seat components, and sealing arrangements to maintain performance under specified cryogenic conditions. Depending on the design, an extended stem or bonnet can help keep the stem packing and actuator away from the coldest process zone. Manual, pneumatic or electric actuation options may be available to meet different operating and automation requirements.

2-Piece Cryogenic Ball Valves are used in liquefied natural gas (LNG) facilities, industrial gas processing plants, cryogenic storage systems, liquid nitrogen applications and other low-temperature process installations. Depending on the specified materials, pressure rating and sealing configuration, they can be selected for compatible 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, connection type, extended stem requirements and leakage performance. Buyers should also consider thermal contraction, low-temperature sealing reliability, actuator compatibility and maintenance access. For liquid oxygen service, material compatibility and cleanliness requirements must be carefully verified. The complete valve assembly must be specifically rated for the intended cryogenic duty, as standard ball valves may not be suitable for extremely low temperatures. Selecting the appropriate two-piece valve configuration helps support dependable isolation, safe operation and consistent performance under specified cryogenic conditions.
