Wireline Retrievable Safety Valve (WLRSV)

Wireline-Retrievable Safety Valves

STAR Wireline-Retrievable Safety Valves offer premium features similar to a tubing retrievable safety valve and are landed in safety valve landing nipples that are equipped with a control line connected to the surface control system. This configuration enables the safety valve to be easily retrieved for repair or maintenance. When assembled to a wireline lock, the assembly can be installed in a safety valve nipple. Hydraulic control line connects the safety valve nipple to the surface emergency shut-down system. Loss of control line pressure will close the valve and shut-in the well. These wireline valves are premium valves due to the use of non-elastomeric seal material, metal-to-metal housing threads, high tensile strength metallurgy, and unique HP/HT packing and piston seal stacks when required by the application. These design features are imperative when considering applications for big bore, high temperature, high pressure, extremely corrosive, and hostile.
