High Pressure High Temperature Globe Valve

JQF Valve is a leading valve manufacturer in China, who specializing in high performance hydraulic control valves. Our high quality high pressure high temperature globe valves rely on a robust, specialized structure to ensure leak-free operation under extremely high pressures, while also preventing seal deformation or loosening at appropriate temperatures. Due to their high-temperature and high-pressure resistance, as well as ease of disassembly and maintenance, these customized high pressure high temperature globe valves are widely used in power, electrical, electro-mechanical equipment engineering, and electrical control equipment engineering.

1. Self-tightening sealing cavity: The high pressure high temperature globe valve features a pressure-reinforced sealing design, with standard welded bevels at the inlet and outlet ends.
2. Hard alloy sealing system: The valve disc/seat sealing surface is made of cobalt-based tungsten-chromium-cobalt alloy, with a temperature resistance limit of 650℃ and a 300% increase in wear resistance. After 50,000 opening and closing cycles, the sealing surface integrity rate is ≥98%.
3. High-strength composite valve stem: Tempered and heat-treated matrix plus surface nitriding treatment.
4. Deep cavity corrosion-inhibiting stuffing box: Corrosion inhibitors are added to achieve zero leakage, reducing frictional torque to 60% of the standard structure.
