Introduction to the internal structure and performance of air-controlled sand control valve :
The air-control sand control valve can make the positive-acting air circuit still open after the positive-acting coil is powered off, and it will be maintained until the reverse-acting coil is energized.
When the reverse acting coil is energized, the reverse action gas path is turned on (there is air in the reverse action air outlet). Even if the reverse action coil is powered off, the reverse action gas path is still on and will remain until the positive action coil is energized. .
Performance characteristics of air-controlled sand control valve controller:
First, it is equipped with a manual operation button, which can facilitate the debugging and operation of the equipment.
Second, there are obvious setting marks on the printed circuit board, which can facilitate the setting of the control instrument.
3. It adopts waterproof shell structure, combined with waterproof connector, can be used in outdoor dust environment.
Fourth, the use of industrial-grade chips as the control core.
Fifth, the air control sand regulating valve has work instructions for each output point, which can quickly determine the status of the output point.
