Product Parameters
Pneumatic O-type cut-off ball valve. It has the advantages of simple structure, small size, light weight and convenient operation, and can be widely used in automatic regulation and remote control of industrial production processes such as petroleum, chemical industry, hydropower, light textile, etc.
Structural Principle of Pneumatic O-type Cut-off Ball Valve:
An O-type ball valve is composed of components such as a valve body, a ball, a valve shaft, a sealing ring, packing, and a pressure plate.
The actuator is composed of main components such as gas, piston, gear type, output shaft, cylinder head, bearing, guide ring, piston bearing bush, adjusting bolt, and "O" ring.
Working Principle of Pneumatic O-type Cut-off Ball Valve
The actuator is connected to the valve via a connecting shaft. After air pressure is input into the cylinder, it acts on the piston to generate a certain thrust, which drives the gear-type output shaft to rotate under the push of the piston, thereby driving the valve shaft to rotate, so that the ball of the ball valve rotates in the valve, changing the flow area of the valve and achieving the purpose of changing the flow rate of the medium passing through the valve.
