Pneumatic ball valves are generally not used alone, and are generally equipped with various accessories, such as solenoid valves, air source processing triplets, limit switches, positioners, control boxes, etc., for the purpose of local control and remote centralized control. Valve switches can be controlled in the control room, without the need to go to the site or high altitude and dangerous areas for manual control, It saves human resources, time and security to a large extent. 　　

The function of the material can not only effectively help the ball valve to play a good anti-static role, but also enhance the service life of the ball valve itself. Now it is basically made of ethylene materials, with good lubrication, and the ball has been effectively inhibited in terms of wear ratio.
