3 Pieces Trunnion Mounted Forging Ball Valve

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.
