How To Position Pneumatic Actuator Valve

Update time:2021.03.01       Views:89

How does the pneumatic actuator drive the pneumatic ball valve and control the opening (the angular stroke is the angle)?

The switch type pneumatic ball valve is generally realized by a solenoid valve + echo (or limit switch).

Regulating pneumatic ball valves are usually realized with valve positioners. The feedback rod of the valve positioning is connected with the valve rod, and by comparing the feedback signal with the system control signal, the ball valve is moved in the direction of reducing the difference, so as to achieve precise control.
