1、 ZDF series multifunctional solenoid valve features:

Removing the bypass isolation installation pipeline with manual function eliminates the need for three manual valves, allowing for online maintenance and greatly reducing costs. The applicable range of medium viscosity can be adjusted to achieve universal use of gas, water, and oil, making it convenient for procurement, storage, installation, and maintenance.
The opening and closing time of the valve can be adjusted to meet various requirements, effectively preventing water hammer damage.
The valve opening can be adjusted to a preset maximum and minimum opening, improving the accuracy of automatic control.
The wear of the main valve can compensate for and extend the service life of the valve, withstanding a long-term test of fifteen years.

2、 Structure principle of ZDF series multifunctional solenoid valve:
The ZDF series multifunctional solenoid valve cleverly combines a pilot solenoid valve, a manual valve, and a throttle valve. The pilot valve receives an electrical signal switch and drives the main valve to operate. Adjusting screws A and B can adjust the applicable range of medium viscosity and the opening and closing time of the main valve, and can compensate for the wear of the main valve. When the pilot valve needs maintenance, simply tighten the adjusting screw B and isolation screw C to remove it, and manual screw operation can be used. This screw can also be used to preset the maximum or minimum flow rate for automatic control of solenoid valves.
