Type 'H' Back Pressure Valves and Two-Way Check Valves
G.B. Industry's type 'H' back pressure valves (BPV) are used to safely seal tubing pressure up to 20,000 PSI during tree installation, remove the blowout preventer, and circulate fluid back down the tubing. If the tree above the tubing needs to be pressure tested instead, the 'H' two-way check valve (TWCV) is landed in the tubing hanger to allow testing of pressure up to 20,000 PSI. Shallow threads on the 'H' Back Pressure and Two-Way Check Valves provide strength for extreme pressure with minimum reduction in bore size, providing a passage of API drifts for the size of the tubing suspended.
Removal and installation tools are available for all BPV and TWCV sizes, for installation into and removal from tubing hangers. We also manufacture 'H' BPV thread chasers to thread within the tubing hanger, 'H' type solid test plugs to test wellhead equipment, and repair kits available in all sizes and material trims.
Our Back Pressure and Two-Way Valve Product Line
Our complete Type 'H' product line covers everything needed to install, test, and maintain back pressure and two-way check valves in the field, from the valves themselves to the tools and repair kits that support them.
Back Pressure Valve Applications
We manufacture our Type 'H' back pressure valves to safely seal tubing pressure during some of the most critical moments in wellhead service. Operators land the BPV in the tubing hanger profile to isolate wellbore pressure while removing the blowout preventer or installing the production tree, and to allow fluid to be circulated back down the tubing without exposing personnel to well pressure.
Common back pressure valve applications include:
- Isolating tubing pressure during blowout preventer removal
- Landing the valve ahead of production tree installation
- Circulating fluid down the tubing during well intervention
- Supporting heavy lift operations over the wellhead
Two-Way Check Valve Applications
Our Type 'H' two-way check valves seal pressure from both directions, which a one-way back pressure valve cannot do. Operators land the TWCV in the tubing hanger when the tree above the tubing needs to be pressure tested rather than isolated, letting crews verify the integrity of the tree and blowout preventer assembly before returning the well to production.
Common two-way check valve applications include:
- Pressure testing the tree and blowout preventer assembly
- Balancing pressure across the valve during removal
- Verifying wellhead integrity after servicing
Benefits of Our Back Pressure Valves and Two Way Check Valves
Every Type 'H' BPV and TWCV we manufacture goes through the same in-house process, from raw material to final hydrotest, so operators receive consistent quality across every order.
- Manufactured in the USA, ranging in size from 2 inches to 6-5/16 inches OD, and available in all API material trims
- Hold the highest well pressures on the market for all API material trims
- Assembled, tested, and stenciled in-house
- API-Monogrammed with in-house Hydro-Test

FAQs
A back pressure valve is a one-way check valve. It blocks pressure from below while still allowing fluid to be pumped down into the tubing string. A two-way check valve seals in both directions, which lets crews pressure test the tree and blowout preventer assembly rather than simply isolating the well. Both valves land in the same profile within the tubing hanger, so choosing the right one comes down to whether the operation calls for isolation or pressure testing.
A lubricator is only necessary when the valve needs to be installed or removed while the well is under pressure. Crews thread the valve onto a polished rod and work it through the lubricator's stuffing box, which lets them run or retrieve the valve without exposing personnel to wellbore pressure. If the well is not under pressure at the time of installation, a lubricator is not required. We manufacture BPV lubricators specifically for this purpose.
Type H and Type B back pressure valves perform the same function. The difference is the thread profile machined into the tubing hanger. Type H valves are manufactured to fit the H-profile most commonly used across API wellhead systems, while Type B valves are machined for hangers built to the B-profile. Confirm which profile your tubing hanger uses before ordering a replacement valve.
