Features and Benefits

All basic design features of TH-Valve’s cast steel check valves are adapted to special service conditions at cryogenic temperatures, additional features are:

1. Sealing with Hard-Facing: Our valves can employ a hard-faced sealing mechanism to enhance durability and ensure effective sealing.

2. Choice of Anti-Rotation Disc: Customers have the option to include an anti-rotation disc, which prevents the valve from rotating unintentionally during operation.

3. Internal Hinge Pin & Hinge Design for Leak Prevention: The valve incorporates an internal hinge pin and hinge design to safeguard against external leakage, maintaining a secure seal.

4. Optional Soft Seat with PTFE or PCTFE: Customers can choose to have a soft seat with either PTFE or PCTFE material, providing additional sealing options to suit specific requirements.
