Product Detail

The Elgiloy Spring Energized PTFE Lip Seal Trunnion Ball Valve is a state-of-the-art solution designed for high-performance sealing in cryogenic and highly corrosive environments. Unlike traditional O-ring seals that may harden or lose elasticity in extreme cold, the Lip Seal utilizes an Elgiloy spring—a specialized super-alloy with exceptional fatigue resistance—to provide constant energizing force to the PTFE jacket. This ensures a bubble-tight seal from vacuum to high pressure (Class 2500) and in temperatures ranging from -196℃ to +200℃. Its trunnion-mounted design minimizes operating torque, making it the premier choice for LNG, hydrogen, and aggressive chemical services.

Design Description

Elgiloy Spring-Energized Seats: The use of Elgiloy (Cobalt-Nickel alloy) spring backing provides superior corrosion resistance, high fatigue strength, and constant seat loading against the ball across wide temperature fluctuations.
Marine-Grade F316 Construction: Forged F316 stainless steel body and trim provide maximum defense against pitting and crevice corrosion in harsh marine salt-spray atmospheres.
Trunnion-Mounted Stability: Fixed-ball design absorbs high pipeline thrusts and prevents ball jamming, ensuring smooth and reliable operation in high-pressure offshore lines.
Fugitive Emission & Fire-Safe Compliance: Certified to API 607 fire-safe standards and engineered with low-emission stem packing to protect marine ecosystems from hydrocarbon leaks.
