Key Features
Robust Trunnion Support Design
Trunnion-mounted ball absorbs axial loads under high pressure, reducing torque and ensuring long-term sealing stability.
Spring-Energized Seat Sealing
Spring-loaded seats maintain reliable sealing during low-pressure start-up and pressure fluctuations.
SPE / DPE Seat Options Available
Single or double piston effect seat designs available to meet different pressure relief and safety requirements.
Integrated DBB with Bleed Port
Double Block and Bleed configuration enables cavity pressure relief and sealing integrity verification.
Fire-Safe Construction for Hydrocarbon Service
Designed to maintain sealing performance during fire exposure for emergency isolation.
Optional Emergency Sealant Injection
Seat and stem sealant injection available upon request for temporary sealing under abnormal conditions.
Product Details
SLVCN Class 1500 Top Entry Trunnion Mounted Ball Valve is designed for critical isolation in high-pressure and demanding service conditions, commonly found in oil & gas, chemical processing, power generation, and other severe industrial applications.
The valve features a trunnion-supported ball combined with a Double Block and Bleed (DBB) sealing system, ensuring positive isolation and controlled cavity pressure management under high differential pressure.
Its top entry construction allows in-line inspection and maintenance without pipeline removal, significantly reducing downtime in continuous operation systems. A one-piece cast WCB body provides high structural integrity while maintaining cost efficiency for large-size and high-pressure installations.
Safety-oriented design elements, including fire-safe construction, anti-static device, and anti-blowout stem, support reliable operation in hazardous services. For sour gas environments, materials and sealing systems can be supplied in compliance with NACE MR0175 requirements.
