Cryogenic Globe Valves

Parker Bestobell's cryogenic globe valves feature an innovative loose flange bolted bonnet design that allows for thermal expansion and contraction, therefore eliminating leakage at the bonnet gasket.

Полное описание продукта

Parker Bestobell provides a wide range of high performance cryogenic globe valves, which feature a unique loose flange bolted bonnet design. The design allows for thermal expansion and contraction, therefore eliminating the risk of leakage at the bonnet gasket.
Extremely durable, these valves deliver smooth operation and reduced closing torque by use of a PTFE anti-friction disc between the valve spindle and the disc assembly.
Extended spindle valves are available for liquid service, along with standard spindle lengths for use on ambient gas requirements.
The range is available with an actuated option, using compressed air to open and a spring to close. Double actuation is available upon request.
