TRM-5 tubing-retrievable, surface-controlled subsurface safety valve is a general-service, self-equalizing, cement-through flapper valve with a premium rod piston and metal-seal body joints. This valve features rod-piston actuation; metal-to-metal seal body joints; a rugged flapper-closure mechanism; and a minimum number of critical, static, and dynamic seals. This combination is designed to maximize reliability in cemented monobore completions in sweet to moderately corrosive environments.
A modular design enables flexibility in material and engineering options, including a wide range of nipple profiles.
The internal equalizing system 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. The flapper mechanism also has full metal-to-metal sealing, and it meets API and ISO a leakage-acceptance criterion.
A unique lockout mechanism enables a simple slickline procedure to permanently lock the valve open and initiate secondary hydraulic communication.
