Tips: Pneumatic actuated ball valve working principle
Pneumatic actuated ball valve is a kind of pneumatic valve, which is driven by air source. Pneumatic ball valve is composed of a pneumatic actuator and a ball valve, which not only saves time and effort, but also can control multiple ball valves at the same time through the controller. The compressed air enters the pneumatic actuator to drive the ball valve to turn 0~90°, open and close the valve to control the size of the fluid. The valve positioner can be assembled according to the working conditions, so that the ball valve can adjust the medium. When the ball valve rotates to 90°, the valve is closed, thereby blocking the flow of the medium.
Favorable price flanged type pneumatic actuated ball valve comes with 5 inch fluid port, 1/4 inch air supply port, stainless steel body material, reliable PTFE plastic seat, optional 2 way or 3 way. Air powered ball valve is widely used for water, gas, oxygen and other air and fluid control.
