Orion Gas Lift Valve

SAZ 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 dome charge provides the closing force for the valve. When injection gas 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.
