Reliance Conventional, Tubing-Retrievable, Surface-Controlled Safety Valve

Overview Library

Self-equalizing flapper-type valves for working pressures up to 5,000 psi

Reliance conventional, tubing-retrievable, surface-controlled safety valves are engineered to provide industry-leading reliability while remaining highly cost-effective. A number of design elements maximize long-term performance and reduce potential leak paths.

Design features that maximize reliability

The valves are operated by a single rod piston with a premium sealing system. To further increase reliability there are only two body joints, which feature a proprietary thread design. The premium flapper mechanism also has full metal-to-metal sealing, together with a secondary soft seat, and it meets leakage-acceptance criteria substantially more stringent than API and ISO specifications. Designed with a flapper lock-open system and an all-metal communication system for secondary valve installation, the Reliance safety valve includes a tested and proven inverted dual-ferrule control line connection for maximum reliability. 

Wide range of options

These versatile safety valves are available in a range of sizes, nipple profiles, and tubing connections, for conventional installations with working pressures up to 5,000 psi [34,475 kPa] and setting depths to 1,500 ft [457 m].
