Pneumatic O-type shut off ball valve
With the features of small fluid resistance and fast opening and closing, the pneumatic O-type shut off ball valve is a valve with the smallest fluid resistance, it takes the compressed air as dynamic force, use the mechanical transmission of gears to actuate valve stem through the piston rack, rotate the ball body for 0~90° by means of the torque transmitted by angular travel and complete rapidly the opening and closing action or controlling action. The channel of ball core is smooth, difficult to deposit media and can perform pipelined pigging. It has also the advantages of simple structure, light weight and excellent sealing performance.
