Orion GV Conventional IPO Valve
Orion GV Conventional Injection Pressure Operated (IPO) gas lift valves are available in 1.0” and 1.5” diameter. The valve is controlled by injection gas pressure (casing pressure). The valve is installed on a conventional mandrel which is deployed on production tubing. The valve has bellows assembly that contains a nitrogen charge over damping fluid. The nitrogen charge, located inside the dome, acts on three ply MONEL bellows to hold the valve in the closed position. The valve opens when combined forces of injection gas pressure & tubing pressure exceeds the closing force, the bellows compress, lifting the valve stem off the seat, and allowing gas in the casing to be injected through the valve into the tubing.
Features
- Body material in stainless steel SS304/SS 316L, 17-4PH and Monel.
- Three-ply Monel bellows.
- Mechanical stop prevents bellows over stroke.
- Viscous fluid shear dampening prevents bellow fatigue and stem chattering.
- Tungsten Carbide ball and ball stem assembly.
- Replaceable floating Monel seat (also available in Tungsten Carbide material)
- Silver brazed bellows connections
