Revata Engineering's Tubing Retrievable Injection Pressure Operated Gas Lift Valve are primarily controlled by injection gas pressure. The valve, when installed on outside mount tubing retrievable mandrels, is used to control gas pressure and its flow from the annulus into the tubing.

The valve is designed with a sealed chamber, including a three-ply bellows assembly that contains a nitrogen precharge, which provides the closing force of the valve. When injection gas pressure exceeds the closing force, the bellows compresses, thus lifting a valve stem off a seat allowing gas to be injected through the valve.

These valves are available in either Stainless Steel or Nickel alloys for corrosion resistance in wells with high concentrations of H2S or CO2. Elastomeric materials for the valve are available for standard service or special service to suit individual well conditions.

Please refer to our SPARES FOR GASLIFT VALVES for more details on spares available for Gas Lift Valve repair and maintenance.

FEATURES & BENIFITS:

Our WLR IPO Gas Lift Valves are available in Stainless steel or premium materials.

The Gas Lift Valves use Three-ply Monel® 400 bellows.

The Bellows connections are Silver Brazed.

Mechanical stop feature prevents the bellows overstroke.

A viscous Silicone based fluid is used to create a fluid shear which dampens the bellows preventing damage to it as well as preventing pounding of the stem to the seat.

Tungsten carbide balls ensure long lasting operation.

The replaceable floating Monel® 400 seats. Tungsten Carbide seats are available upon request.

Optional reverse flow check valve.

Pressure rating up to 1,800 psi (124 bars) test rack open.

Temperature rating of 250°F (121°C) (Standard Service)

Compatible with other manufacturers of side pocket mandrels.
