Unique sleeve-closure system Proven rod-piston actuaƟon system
The Camco* PGV-S sleeve-closure type gas vent safety valve that isolates annular flow below the packer. The PGV-S designed to control the flow of annular vent gas in electrical submersible pump installaƟons, and injecƟon gas in low volume gas liŌ installaƟons. The PGV-S valve is also commonly aƩached to the top of mulƟ-bore packer. The packer blocks annular flow, provides a path for produced fluids, ESP power cable access, and a vent path for separated gas and/or break-out gas in ESP applicaƟons. The PGV-S is normally installed with a dedicated hydraulic control line for posiƟve surface control of the gas vent safety valve, but may also be installed using a common control line with the tubing safety system. The PGV-S is rated to 5,000-psi [34,474 kPa] working pressure. The PGV-S valve design features an innovaƟve sleeve-closure system. The proven rod-piston hydraulic actuaƟon system provides predictable operaƟon, decreased fricƟon, a reduced hydraulic chamber area, and deeper seƫng depths than valves with concentric operaƟng pistons. OperaƟon Open When the valve is open, annular gas flows through the packer and valve. It exits into the casing annulus above the packer through the ports in the valve’s closure sleeve and body. Close If hydraulic control line pressure is lost for any reason, the spring-loaded closure sleeve moves upward allowing the valve to close and shut in the annulus below the packer.

Wireline Retrievable Vent Override Valve specified or added as a subassembly at a later date in the field. If equipped with the Annular lock-out feature the PGV-S-ALO can be permanently locked in the open posiƟon to by-pass the closure mechanism. Applied annular pressure above a predetermined value will acƟvate the lock-out. Engineering Data for PGV-S Gas Vent Override Valve Flow area (Bore,) sq in [sq mm]
