Type H Back Pressure Valves
Posted by Michael Thomas on 12th Feb 2015
Type H Back Pressure Valves are used to safely seal tubing pressure while the blowout preventer, BOP, is removed and the Christmas Tree is installed. It also allows circulation of fluid back down the tubing.
Heshka Oil offers back pressure valves as well as the replacement parts for purchasing online here.
A complete Type H BPV consists of the body, piston, pin, spring and OD Seal.
We also offer a remolding service so you can reuse your piston if the Viton material has eroded or been damaged.
