Trunnion Mounted Ball Valves - Valbart Cryogenic Ball Valve
The Valbart Cryogenic Ball Valve meets demanding end-user requirements for leak rate and fugitive emission performance. It's body construction and flexible trim configurations ensure proper safe isolation. It is bi-directional (std) or uni-directional (upon request), side entry or top entry with fire-safe design, with an anti-static feature and automatic cavity relief.
