Product Detail

The Inconel 825 Alloy Double-Lip Trunnion Ball Valve is a high-performance flow control solution engineered for extreme environments involving sulfuric acid, phosphoric acid, and seawater. Constructed from premium UNS N08825 nickel-iron-chromium alloy, this valve offers exceptional resistance to both reducing and oxidizing acids, as well as stress-corrosion cracking and pitting. The innovative Double-Lip seat design provides a redundant sealing mechanism that ensures bubble-tight shutoff at both low and high-pressure differentials, making it indispensable for critical chemical processing and offshore applications.

Design Description

Superior Inconel 825 Construction: Offers excellent resistance to chloride-ion stress-corrosion cracking and phosphoric/sulfuric acid corrosion.
Advanced Double-Lip Sealing: The dual-lip profile creates a flexible yet robust seal that adapts to pressure fluctuations, ensuring long-term leakage prevention where standard seats fail.
Trunnion Mounted Stability: Fixed-ball design minimizes operating torque and maximizes seat life by distributing the fluid load through the bearings.
Corrosion-Proof for Sour Service: Fully compliant with NACE MR0175/ISO 15156, ideal for "sour" oil and gas environments containing $H₂S$ .
Full-Bore Design: Ensures maximum flow capacity and minimizes pressure drop, allowing for easy pigging operations.
