Type 'H' Two-Way Check Valves

Type H Two-Way Check Valves (H TWCV), is designed to fit the same profile in the tubing hanger as back pressure valves (BPV). The two-way check valve holds pressure from both directions while allowing balance when required and is used to test the tree and blowout preventer (BOP) assembly.

G.B. Industry's Type ‘H’ TWCV is available:

in API tubing sizes from 2” to 6-5/16”,
up to 20KSI working pressure
Non-Monogrammed and API Monogrammed
M/C: AA-HH, T/C: P-U, PR2

Our ‘H’ TWCV is designed to:

Balance pressure at removal from the tubing hanger
Corrosion resistance – NACE and API 6A compliant
Enhanced load-bearing – QPQ Nitride
High-pressure seal performance – Viton, HSN, and Nitrile seals

GBI's Two-Way Check Valves are hydrotested and field-proven, successfully used by wellhead manufacturers and repair providers worldwide for over 35 years.
