The Manual Wireline Valve is a compact wireline valve construction; designed specifically to be used as a Single or Dual Ram; for Slickline and Braided Line operations. This allows the performance of work under pressure, on surface equipment, when the line is still in the wellbore.
The Manual Wireline Valve is placed between the wellhead and lubricator assembly.
The Manual Wireline Valve closure design consists of a manual operated stem connected to the ram assemblies. The rams can be closed (or opened) by manually rotating the stems. This permits compression of the rams around the line from opposite sides. A seal is then made which contains well pressure below the ram. Pressure across the ram is equalized through an integral equalizer assembly prior to hydraulically retracting the ram and opening the valve.
The Manual Wireline Valve is available in nominal sizes from 2-1/2” to 5" with working pressure ratings from 5,000psi to 10,000psi, for standard and sour environments.
A Low Torque (Bearing Type Non-Rising Stem Closure) Manual Wireline Valve is available for lower operation torque requirement. It is not advisable to use Manual Wireline Valve for large ID size or high working pressure application due to the high operation torque requirement.
The Hydraulic Wireline Valve should be used for high torque application.
