Stinger

Rotary Lock Traveling Valve

The Stinger is a rotary lock traveling valve used in artificial lift wells which utilizes rod pump configurations. Replacing the traditional ball and seat traveling valve, the Stinger's upper threads connect directly to the valve rod, and the lower threads interface with standard plungers. With a main body of 17–4 stainless steel, the Stinger’s engineered rotary locking action prevents high bottom pressure and prevents loss of fluid recovery by locking open on down stroke. In addition, it can reduce operation and well servicing costs while increasing production.
