Product Sheet TRM-4 Series Reduced OD Safety Valves
General service, reduced OD, premium rod piston tool.
Safety valves
The internal equalizing system in some valves of the series creates a dedicated flow path for wellbore fluid, minimizing effects of erosional velocities.
The premium rod piston system uses a reliable, spring-energized filled Teflon sealing element. Operating within the valve's chamber housing, the system comprises a stepped OD; a compliant down-stop of polyetheretherketone polymer; a static, full-closed metal-to-metal seal; and an integrated piston centralizer.
For maximum reliability, all TRM-4 reduced-OD 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.
