General service, self-equalizing, rod-piston flapper valves

The WRDP-1 is a slickline-retrievable, hydraulically actuated, tubing-pressure sensitive, standard spring subsurface safety valve. It is suitable for a range of subsurface environments, including both production and injection wells and various wellbore fluids—oil, gas, and water. The rod-piston actuator uses premium dynamic seals and is combined with the rugged flapper-and-seat closure mechanism to provide a long-term reliable solution.

The valve is normally supplied with a fit-for-purpose lock that enables proper location in the completion. The WRDP-1 can be used as the primary safety valve by placing it into a hydraulic communication nipple. Alternatively, it can be used as a contingency measure by placing it in a locked-open, tubing-mounted safety valve that is no longer operable.
