ZDK Combined Electromagnetic Air Valve
ONE、Overview
The ZDK-type combined electromagnetic air valve is applied to the braking system of hydroelectric generator units, with compressed air as the working medium. It is used to achieve braking engagement and release, and features a manual operating mechanism. In the event of a power outage, manual operation can be performed, and it is also suitable for use in thermal power, mechanical, metallurgical, chemical, and other industries.
This product has the following characteristics:
Small size, light weight, reliable operation
Electromagnetic iron coils work for a short period of time, with low driving power and are not easily damaged
Equipped with manual control mechanism
Equipped with self-locking function

THREE、Working principle
Automatic control: The manual switch of the pilot valve must be in the red line position. When the pilot valve C is energized, the pressure gas P is discharged from port A; When the pilot valve D is energized, the pressure gas P is discharged from port B; Implement braking and reset functions.
Manual operation: When the electromagnetic pilot valve is powered off, rotate the manual switch of the C (or D) pilot valve to the black line position to achieve manual operation, and return to the red line position to reset the exhaust. C. The D pilot valve cannot be opened simultaneously.
