Welded High-Temperature High-Pressure Globe Valves: Technical Specifications & Applications
Welded high-temperature high-pressure globe valves are engineered for extreme service conditions in industrial applications. These valves feature a linear motion design where the disc moves perpendicular to the valve seat, providing precise flow control and reliable shut-off capabilities.The main stop valve product names of China Stop Valve Network include:Welded High-Temperature High-Pressure Globe Valve,High Temperature and Pressure Power Station Electric Globe Valve,Manual Welding High Temperature and Pressure Globe Valve,Forged Steel Straight-through Globe Valve,Flange Straight-through Low Temperature Globe Valve,Flange Straight-through Throttle Emptying Globe Valve,DIN Angle-type Bellows Globe Valve,Y-type Butt Welded Globe Valve.
Primary Selection Criteria
Critical Service Applications: Ideal for high-temperature and high-pressure media in power generation (thermal/nuclear plants), petrochemical processing, and refinery systems
Flow Regulation: Optimal for throttling applications and flow control on pipelines with nominal diameters ≤50mm
High-Pressure Systems: Essential for synthetic fertilizer production with requirements for PN16MPa or PN32MPa pressure ratings
Abrasive Media Handling: Recommended for coking service applications with straight-through designs featuring hard-alloy trim and removable seats
Key Advantages
Superior Sealing Performance: Low friction between sealing surfaces ensures reliable shut-off
Compact Design: Minimal stroke length allows for quick operation and space-saving installation
Easy Maintenance: Simplified construction with accessible internal components
Leak-Free Connection: Welded ends eliminate potential leakage points common with flanged connections
