1. When the pneumatic actuator is connected to the circuit and the air source of the system, the air enters the A cylinder (B cylinder) through the pipe A or B pipe, and pushes the piston to move to one end, thereby driving the rotating shaft and the ball core to rotate 90° 2. Pneumatic execution The top of the device is linked to the visual device, and when the green mark points to the word 'open', it indicates that the valve is open. 3. When the green light of the echo signal light is on, the valve is in the open position, and when the red light is on, the valve is in the closed position. 4. The positioner can adjust the flow of the valve pipeline. 5. The valve seat adopts an elastic sealing structure, which is reliable in sealing and easy to open and close. 6. The valve stem adopts a bottom-mounted structure with an inverted seal. When the valve cavity is abnormally boosted, the valve stem will not be impacted. 7. The pneumatic piston actuator is made of low-friction material as the bearing sleeve, and the inner and outer surfaces of the cylinder are treated with hard anodized anti-corrosion treatment, which greatly improves the service life of the cylinder.
