Rely on premium rod pistons for maximum reliability

TRM-4P and -4HP series tubing-retrievable, surface-controlled subsurface safety valves feature premium rod pistons that protect the hydraulic piston bore and increase reliability. The valves also have metal-to-metal body joints, a rugged flapper-closure mechanism, and a minimum number of critical seals. This combination maximizes reliability in general-service applications in sweet to moderately corrosive environments.

A modular design enables flexibility in material and engineering options, including a wide range of nipple profiles.

Maximize reliability with metal-seal body joints

The premium rod piston system in these valves uses a reliable, spring-energized filled Teflon sealing element. Operating within the valve's chamber housing, the system comprises a stepped OD; a compliant downstop of polyetheretherketone polymer; a static, full-closed metal-to-metal seal; and an integrated piston centralizer. 

For maximum reliability, all TRM-4 and -4H valves have only two body joints and use proprietary threads to achieve a solid, metal-to-metal seal. The premium flapper mechanism also has full metal-to-metal sealing plus a secondary soft seat, and it meets a leakage-acceptance criterion that is substantially more stringent than API and ISO specifications.

A unique lockout mechanism enables a simple slickline procedure to permanently lock the valve open and initiate secondary hydraulic communication. A second option enables locking open the valve without activating secondary hydraulic communication.
