Parker manufactures 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. The range includes actuated and manual options in stainless steel and bronze body materials.
