Trunnion Valves

Trunnion Valves

Trunnion valves are specialized ball valves featuring a fixed ball design, anchored by upper and lower trunnions. This construction allows the ball to remain stable and precisely aligned, effectively managing fluid flow through pipelines under significant pressure or dynamic operating conditions. The fixed ball and independent seat rings reduce torque requirements, enhancing valve operation and lifespan, especially in demanding industrial applications.

Their robust design makes trunnion valves particularly useful in critical process control scenarios where tight shut-off and reliability are paramount. They effectively handle high-pressure, high-temperature, and abrasive fluids, providing reliable sealing capabilities under extreme conditions. The stable anchoring provided by trunnion mounts reduces stress on valve components, improving durability and minimizing maintenance needs, thus optimizing overall system efficiency and reducing operational downtime.

Trunnion valves are widely employed across various industries, including oil and gas, petrochemical, power generation, and chemical processing. They are commonly used for isolation purposes in pipeline systems, emergency shut-off situations, and process control requiring accurate flow modulation. In oil and gas operations, these valves are essential in upstream and downstream processes, supporting safe and efficient operations by effectively controlling crude oil, natural gas, refined products, and other hazardous fluids.

Additionally, trunnion valves are suitable for subsea applications, ensuring leak-free operations even under high external pressures and challenging environmental conditions. Their precision sealing and operational reliability contribute significantly to maintaining safety standards, regulatory compliance, and the integrity of critical industrial processes.
