Product Detail

The Pressure Seal 2500LB RTJ Gate Valve is a high-performance flow control solution engineered for the most demanding ultra-high pressure and high-temperature services. Utilizing a Pressure Seal Bonnet design, this valve converts internal system pressure into a sealing force, ensuring leak-proof integrity where bolted bonnets often fail. Rated for ASME Class 2500, it features RTJ (Ring Type Joint) ends for a robust metal-to-metal connection. This valve is the primary choice for main steam isolation, boiler feed water, and high-pressure hydrocarbon processing.

Design Description

Self-Reinforcing Pressure Seal: The sealing force on the bonnet gasket increases proportionally with internal line pressure, providing a superior seal during high-pressure surges.
RTJ Leak-Proof Connection: Equipped with Ring Type Joint (RTJ) flanges to provide a high-integrity metal-to-metal external seal, essential for high-vibration and high-temperature cycling.
Stellite Hard-Faced Seats: The wedge and seat rings are overlaid with Stellite #6 or similar hard alloys to resist erosion, wire-drawing, and galling at high velocities.
Flexible Wedge Design: Compensates for seat distortion and thermal binding due to rapid temperature changes, ensuring the valve remains operable in extreme cycles.
Fully Guided Travel: Precision-machined wedge guides ensure accurate alignment and minimize friction between the seating surfaces throughout the travel.
