Ball valves are easier to operate at higher pressures due to the control surface being spherical. This means less loading therefore requiring less torque to close the valve, even under extremely high flow rates. This, combined with their quarter-turn configuration, makes high pressure ball valves extremely beneficial in applications such as shut-offs or multiple source selection valves.
Parker high pressure ball valves from Fluid Controls are designed to give a reliable shut-off or switching function, with the upper and lower trunnion bearings providing increased resistance against seizure and therefore offering a longer life valve in extreme applications.
A ball valve uses a hollow pivoting ball to control flow through it. By rotating the ball within its housing you can vary the size of the aperture, therefore the amount of flow. They are usually a quarter-turn valve, meaning that moving the actuator handle though 90 degrees will provide full flow. The valve control handle is usually set in-line with the aperture of the ball allowing for quick visual confirmation of the valve’s state.
