Advantages of the Trunnion-mounted Ball Valve

Lower operating torque

The operating torque of the trunnion-mounted ball valves is reduced due to additional support provided by the trunnion, giving reinforcement to the bottom of the ball and the top.

Ease of operation

A quarter-turn is easier to operate as opposed to valves that a require a full turn. It is preferred by industries that require quick maneuverability and shut-off.

Minimized seat wear

The isolated nature of the trunnion-mounted ball prevents the wear of seats resulting in its durability and longer service life.

High and low-pressure control

It is ideal for high and low-pressure control because of the sealing of the ball valve by a separate spring mechanism.
