Barrier series gas lift orifice valves. Unsurpassed reliability and enhanced well integrity.
The reverse back-check valve is fully qualified as a barrier, providing a positive seal between the tubing and casing annulus. The unique check valve design results in a valve that does not chatter under normal operation.
Change out of gas lift valves (GLV) due to valve failures or non-optimum gas lift design can be costly, especially in offshore and subsea environments.
Interruption of, or non-optimum gas lifted production has a negative impact on field economics. Furthermore, leaking GLV’s often lead to downgrading of the wells integrity level.
Petroleum Technology Company´s (PTC) SafeLift and IsoLift orifice valves have a proprietary orifice and back-check system, which eliminates chatter and wear. This design has proven to have unsurpassed longevity and reliability, which reduces intervention costs. In addition to the valve geometry, PTC offers a unique life of field (LOF) gas lift design process, which ensures optimum design for all phases of the well.
SafeLift’s & IsoLift’s true metal-to-metal seal has been qualified as a well barrier for operators worldwide. It was designed, built and tested in accordance to API 19G part 2 and leak tested in accordance to ISO 14310-V1/ V0. SafeLift valves are designed to be installed in all side-pocket mandrels with 1" & 1.5" pockets, designed according to API 19G part 1. 1.75" SafeLift valves are also available.
