Product Overview
This forged steel high temperature stop valve is designed for extreme high-temperature and high-pressure working conditions. It features an integral forged construction, with the body and sealing system optimized for long-term service at elevated temperatures. Sizes range from DN15–DN50, with pressure ratings up to Class 2500LB. It is mainly used for shut-off and flow regulation of high-temperature steam, thermal oil, hydrocarbon fluids and other high-temperature media.
Widely applied in power stations, petrochemical, oil & gas, and thermal systems, this valve has a compact structure, reliable sealing, excellent high-temperature resistance and long service life. It meets international industrial standards and is suitable for customers worldwide.
Key Features
Integral Forged Steel Body
Made from high-quality forged steel with uniform density, free of blowholes and casting defects. High strength, good impact and fatigue resistance, with a much longer service life than cast steel valves.
High Temperature Resistant Sealing
Equipped with high-temperature resistant seating and packing, ensuring stable sealing performance even at extreme temperatures, no aging, no deformation, no leakage for continuous long-term operation.
High Pressure Rating
Pressure rating available up to Class 2500LB, ideal for ultra-high pressure and high temperature applications with high safety requirements.
Reliable Sealing, Zero Leakage
Disc and seat are precision lapped for tight shut-off. Excellent sealing performance suitable for high-temperature, high-pressure, flammable and explosive media.
Compact Small Bore Design
Specifically designed for small bore pipelines DN15–DN50, compact structure, space-saving, easy and stable to operate.
International Standard Compliance
Dimensions, connections and pressure ratings comply with mainstream international standards, suitable for global markets including Europe, Russia and America.
