Trunnion Ball Valves

Product Description

A trunnion-mounted ball valve is a quarter-turn valve designed to control the flow of media through a pipeline. Unlike floating ball valves, where the ball is held in place solely by the stem, trunnion-mounted ball valves feature additional mechanical anchoring at both the top and bottom of the ball. This design provides enhanced stability and support, making them particularly suitable for high-pressure and large-diameter applications.

Key Features:

• Enhanced Stability: The trunnion anchoring system secures the ball, reducing the risk of displacement under high-pressure conditions.

• Lower Operating Torque: The trunnion design reduces the torque required to operate the valve, facilitating easier manual operation and allowing for the use of smaller actuators.

• Effective Sealing: Trunnion-mounted ball valves often incorporate spring-loaded seats that maintain a tight seal across a range of pressures, ensuring reliable performance in both low and high-pressure environments.

Applications:

Trunnion-mounted ball valves are widely used in industries such as oil and gas, petrochemical, and power generation. Their robust design makes them ideal for applications including:

• Pipeline Isolation: Providing reliable shut-off capabilities in mainline and manifold pipelines.

• Emergency Shutdown Systems: Ensuring rapid isolation of sections within a processing plant during emergencies.

• High-Pressure Fluid Control: Managing the flow of high-pressure gases and liquids in processing facilities.
