Working principle and purpose of the product:

When the pneumatic actuator is connected to the circuit and system air source, air enters cylinder A (cylinder B) through pipe A or B to push the piston towards one end, thereby driving the rotating shaft and ball core to rotate 90 °.

The top of the pneumatic actuator is linked with a visual device, and when the green sign points to the word "open", it indicates that the valve is open.

When the green light of the reply 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.

The locator can adjust the flow rate of the valve pipeline.

D641X flange type pneumatic butterfly valve is suitable for regulating flow and intercepting media on water supply and drainage, gas pipelines in food, medicine, chemical, petroleum, power, textile, papermaking and other industries with temperature ≤ 120 ℃ or ≤ 150 ℃ and nominal pressure ≤ 1.6MPa.
