Automated pvc ball valve is composed of rotary air actuator and ball valve. The automated pvc ball valve has a top-mounted structure, which minimizes the valve body's connecting bolts under high pressure and large diameter settings, increases the valve's reliability, and compensates for the influence of the system's weight on the valve's normal operation. It possesses outstanding flow properties, mechanical strength, and a low pressure drop. Typically, automated pvc ball valves are used in a variety of automatic fields as media splitting, confluence, or flow switching devices.
