International Lift Systems' RPPO-1.0 and RPPO-1.5 wireline retrievable spring loaded fluid operated gas lift valves are used in common annulus dual string gas lift.
The RPPO-1.0 is 1" outside diameter and the RPPO-1.5 is 1-1/2" outside diameter. The valves include a reverse flow check as an integral part. The checks have a dual seating system using an elastomer seal as a first seal and a metal-to-metal secondary seal.
