The Type H Two Way Check Valve is installed in the tubing hanger to allow the Christmas Tree to be tested. The check valve allows pressure to be equalized above and below the seal, providing safe removal from the tubing hanger.
Heshka Oil offers two way check valves as well as the replacement parts for purchasing online here.
A complete Type H TWC Valve consists of the body, piston, O-ring, retainer nut and OD seal.
We also offer a remolding service so you can reuse your piston if the material has eroded or been damaged.
