Production Pressure Operated Gas Lift Valves
Vanoil Completion Systems RF-1 and RF-2 wireline retrievable spring loaded fluid operated gas lift valves are used in common annulus dual string gas lift.
The RF-1 is 1” outside diameter and the RF-2 is 1-1/2” outside diameter. The valves include a reverse flow check as an integral part. These checks have a dual seating system using an elastomer seal as a first seal and a metal-to-metal secondary seal.
