Product Detail

The Inconel 825 900LB Trunnion Ball Valve with Spring Energized Seal is a high-integrity, heavy-duty flow control solution engineered for extreme-pressure environments and highly corrosive chemical or sour gas processes. Constructed from solid or heavy-overlay Inconel 825 (UNS N08825 nickel-iron-chromium alloy), the valve offers exceptional resistance to sulfuric acid, phosphoric acid, chloride stress corrosion cracking, and localized pitting. Built to withstand Class 900 high-pressure ratings, it incorporates a robust trunnion-mounted fixed-ball design to minimize operational torque under immense differential pressures. Combined with an advanced Spring-Energized Sealing mechanism, it ensures continuous, self-adjusting contact against the ball, delivering bubble-tight shut-off across cyclical pressure surges.

Design Description

Inconel 825 Super-Alloy Defense: Offers outstanding resistance to oxidizing and reducing acids, stress corrosion cracking (SCC), and marine environments, making it ideal for aggressive chemical loops.
Spring-Energized Sealing Mechanism: High-performance metal springs behind the seat insert provide continuous mechanical pre-load, guaranteeing reliable sealing performance even under low-pressure or zero-pressure conditions.
Trunnion-Mounted High-Pressure Stability: Fixed-ball design absorbs high pipeline thrusts in Class 900 systems, preventing ball jamming and ensuring smooth, low-torque actuation.
Fugitive Emission & Fire-Safe Design: Complies with strict environmental and safety standards, featuring low-emission stem packing and API 607 fire-safe certification.
