Frequently Ask Questions
A Floating Cryogenic Ball Valve uses a free-floating ball that moves slightly under line pressure to press against the downstream seat, providing reliable sealing in cryogenic applications.
The extended bonnet keeps the stem and packing area away from extreme cryogenic temperatures, helping maintain sealing performance.
A floating ball is supported mainly by the seats and line pressure, while a trunnion-mounted ball is mechanically supported at the top and bottom. Floating designs are generally suited to smaller sizes and moderate pressure applications.
Yes. Floating Cryogenic Ball Valves can be fitted with pneumatic actuators for remote and automated operation.
The ball is not fixed to the stem and can move slightly with line pressure. This movement helps the ball press against the downstream seat for tight shut-off.
Depending on the design and materials, Floating Cryogenic Ball Valves can be suitable for temperatures down to approximately -196°C.
Alis Valves manufactures and supplies Floating Cryogenic Ball Valves for LNG, industrial gases, and other demanding low-temperature applications.
Yes. Electric actuators can be provided where electrical automation is required.
