The pneumatic ball valve can be closed tightly only by using the pneumatic actuator to rotate 90 degrees with the air source and a small rolling torque. Thoroughly equivalent valve body cavity provides a straight flow passage with little resistance for the medium. Generally, ball valves are most suitable for direct opening and closing. The primary feature of the ball valve is its compact structure, easy to operate and repair, suitable for water, solvent, acid, natural gas and other general operating media, and also suitable for media with poor operating conditions, such as oxygen, hydrogen peroxide, methane and ethylene. The ball valve body can be integral or combined.

If the valve we are using is a downward pushing type, the actuator of the electric butterfly valve itself is not too reasoning, it will not achieve our use effect. Then we can push the actuator with greater force during maintenance, or install a balanced style spool, which is also to reduce the impact of media on our work quality. If you have a careful investigation, you will find that many failures are caused by the unreasonable existence of a medium. Therefore, we should pay enough attention to this point.
