Pinnacle HPHT Tubing-Retrievable, Surface-Controlled Safety Valve

Overview Library

Flapper-type safety valves for conventional, HPHT, deepset, and severely corrosive applications

Pinnacle HPHT tubing-retrievable surface-controlled safety valves are designed for working pressures from 15,000 psi to 20,000 psi and temperatures up to 400 degF.

Designs incorporating technological advancements and years of experience

The valves use an enhanced premium rod piston with a hydraulic-actuation sealing system incorporating reliable metal-to-metal dynamic seals and spring-energized, filled Teflon sealing elements; a static up-stop and down-stop; and a precision piston tube that prevents deformation at high pressures. 

A rugged, metal-to-metal INCONEL flapper closure mechanism and secondary soft seal meet leakage-acceptance criteria substantially more stringent than API and ISO specifications. The compact design of Pinnacle valves incorporates the latest materials and technological advancements resulting from years of experience in high-pressure valve design.

Protection from debris

For maximum reliability, all Pinnacle valves use proprietary threads to achieve a metal-to-metal seal and include a compact flow tube nose seal to minimize the intrusion of debris into the flapper and power spring systems. Valves are available for production tubing sizes ranging from 3 1/2 in to 5 1/2 in.
