Subsurface safety valves for conventional, high-rate gas, and deepset installations

For sweet to severely corrosive environments and high-rate gas production or injection wells, SlimTech reduced-OD, tubing-retrievable, surface-controlled safety valves (SSVs) provide exceptional versatility and reliability with a compact design that meets or exceeds API and ISO standards.

These valves feature rod-piston actuation, metal-to-metal seal body joints, and rugged flapper-closure mechanisms.

Maximize reliability for high-rate closure

The valves use a single rod piston with reliable, spring-energized, filled Teflon sealing elements; a static, full-closed, metal-to-metal seal; and a static, full-open seal and centralizing system. For maximum reliability, every SlimTech valve has only two body joints and uses proprietary threads to achieve a reliable, metal-to-metal seal. A patented system dramatically simplifies secondary communication.

For optimal valve OD, the SlimTech valve features the unique premium curved-flapper mechanism with full metal-to-metal sealing and a secondary soft seat. The robust flapper mechanism is designed to withstand the extreme forces experienced during high-rate closure. The standard SlimTech valve has been tested to close at rates up to 450 MMcf/d at a flowing pressure of 600 psi. A high-rate version has been tested to close at rates up to 505 MMcf/d at a flowing pressure of 600 psi.

The flapper system is manufactured with a leakage acceptance criteria 50 times better than the standard API and ISO specifications.
