Cryogenic

Cryogenic

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.

Improved seal performance at extremely low temperatures enabled by isolating stem seals from cold media

Guaranteed optimum leakage resistance in demanding cryogenic applications via primary energized lip seal

Increased reliability and safety from automatic discharge of excessive body pressure by internal self-relieving system (top- and side-entry models)

Plant and personnel protected by anti-blowout design that ensures the stem is retained by the stem cover

Environmental compliance assured by zero-emission design

Reduced actuation costs, as seat design minimizes the torque required to operate the valve without losing the sealing power

Ball and stem are independent to minimize the effect of the side thrust generated by the pressure acting on the ball

Accurate machining of stem and bonnet sealing surfaces ensures compliance with the most severe pollution-control regulations

Valve designs are available with extended bonnets for applications in extreme temperature service
