Pneumatic ball valves sometimes experience internal leaks. The following are some causes of internal leakage and their common treatment methods: The zero position of the pneumatic ball valve actuator is not set, and the valve has not reached the fully closed position. How to adjust: Close the valve manually (make sure it is fully closed) and close the valve manually. Push on the side that is a little hard to screw in, then return it half a turn (valve open direction). Then adjust the valve.
Selection of stroke pneumatic ball valve: the valve rotates 90° to open and close. The actuator torque is insufficient to easily reach the fully closed position without pressure. Unable to suppress rotational force and liquid, no thrust. Treatment method: switch to a larger thrust actuator or switch to a balanced spool to reduce the uneven force on the medium.
