Trunnion Mounted Ball Valve – High-Performance Solutions from Wandong Valve Product
Wandong Valve Product offers a comprehensive range of Trunnion Mounted Ball Valves, engineered for superior performance in demanding industrial applications. As a leading China Trunnion Mounted Ball Valve manufacturer, we provide valves that ensure reliable sealing and efficient flow control in pipelines.
TRUNNION TYPE BALL VALVE Applications
Oil & Gas: Subsea pipelines, refinery process lines, and high-pressure gas transmission.
Chemical & Power Plants: Handling corrosive fluids (e.g., acids, ammonia) and superheated steam.
Cryogenic Systems: LNG storage, liquid nitrogen transport, and low-temperature processing
Trunnion Mounted Ball Valve Main Features
Fixed ball valves feature a stationary ball anchored by upper and lower stem bearings, ensuring stable sealing under high-pressure conditions. Unlike floating designs, the ball remains fixed while the seats absorb system pressure, making them ideal for large-diameter pipelines and extreme operational environments.
High-Pressure Reliability: Fixed trunnion structure withstands pressure surges and vibration.
Bidirectional Sealing: Uniform sealing performance in both flow directions.
Low Maintenance: Modular seat assemblies allow quick replacement without pipeline disassembly.
Trunnion Mounted Ball Valve Design Features:
Full port or reduced port
Trunnion-mounted ball
Blowout-proof stem
Double block & bleed
Emergency sealant injection
Cavity pressure self relief
Fire safe design to API 607
Trunnion-Mounted Ball: Dual stem supports minimize operational torque and prevent ball displacement under high pressure.
Double Block & Bleed (DBB): Integrated drain/vent ports enable safe maintenance and leakage verification.
Full-Bore or Reduced-Bore: Optimized flow paths for minimal pressure loss or throttling control.
Fire-Safe Design: Anti-static devices and fire-resistant graphite seals comply with API 607/6FA standards.
