Our Cameron® style two-way check valves fit the same profile as the back pressure valves. It holds pressure from both the well and tree sides and allows for equalization when required. Our two-way valves are used extensively for testing of the Christmas tree.
We have produced Type "H" TWC’s in conjunction with the Type "H" BPV’s since 1973, and they are available in the same sizes as their counterpart. We stock sizes from 1 ¼” OD all the way up to 6 ½” OD in 4130 Alloy trim, 17-4 SS trim, and 718 Inconel trim.
Material classes (API 6A/NACE MR0175) are as follows:
4130 Alloy = AA, DD
17-4 SS = EE FF
718 Inconel = HH
Working Pressures are 15,000 PSI on 1 ¼”-5” OD and 10,000 PSI on sizes greater than 5” OD.
