4 1/16'' 10K Tandem Hydraulic Wireline Valve
To enable well pressure to be isolated and released from the lubricator without closing wellbore valves.
The solid block body has a vertical full bore section to allow movement of wireline tools in and out of the wellbore.
The horizontal ends of the cross often referred to as “The Body” or “Ram Housing” contains rams, with inner and outer seals. These rams can be manipulated in and out of the housing with handles fastened to threaded stems or Lockout Pins for closing and opening the Rams.
An Equalizing Assembly is located on the side of the main Body along with two Bleed Off Ports and located 90o from ram housings. By opening an Allen wrench operated valve seat the equalizing assembly allows pressure to equalize from the wellbore to the lubricator with the rams closed.
Wireline Valve is fitted with compatible hand/quick unions for installation with surface equipment.
Wireline Valve typically seal and hold pressure from below.
The wireline valve is used to isolate wellbore pressure when lubricator/stuffing box pressure integrity is lost.
Contain well pressure for lubricator removal, should wellhead valves malfunction or freeze off.
