Product Detail

The Inconel 625 Overlay Lip Seal High Pressure Ball Valve is a top-tier engineered flow control solution tailored specifically for severe marine engineering, subsea, and offshore high-pressure production platforms. To combat aggressive seawater corrosion and sour gas (H2/CO2) environments, the critical internal wetted areas of the valve body and closure components are armored with high-integrity Inconel 625 weld overlay. Combined with an advanced Lip Seal design, which utilizes fluid pressure to energize and enhance contact tightness against the ball, this valve delivers exceptional bubble-tight shut-off under extreme pressures (up to Class 2500 or 15000 PSI). Built in accordance with API 6D and API 6A specifications, it guarantees uncompromised safety and longevity in the world's most hostile marine environments.

Design Description

Inconel 625 Weld Overlay: Critical sealing surfaces and cavity areas are cladded with Alloy 625 (UNS N06625), offering world-class resistance to pitting, crevice corrosion, and chloride-induced stress corrosion cracking.
Self-Energized Lip Seal Design: The spring-loaded or pressure-assisted lip seal mechanism flexes under line pressure, ensuring continuous, dynamic contact with the ball even during pressure surges or thermal cycles.
Heavy-Duty Trunnion Construction: Fixed-ball design handles massive high-pressure thrusts, minimizing operational torque and preventing seat deformation.
Deep-Sea & Offshore Reliability: Designed to withstand high external hydrostatic pressures and internal high-pressure containment, meeting NACE MR0175 / ISO 15156 sour service requirements.
