摘要： The pilot type controlled electromagnetic valve system in accordance with the present invention is opened and closed principally by means of automatic remote control.
The controlled valve system comprises a main valve F; a pilot valve G for opening and closing the main valve F by means of the fluid pressure on the primary side; a latching solenoid H for opening and closing the pilot valve G; and a solenoid drive control unit I for driving the solenoid H by supplying a discharge current from a capacitor to the solenoid.
A pulse discharge current is supplied to the solenoid H from the capacitor C only when the pilot valve G is opened or closed, and no excitation current is supplied continuously through the coil of the solenoid. As a result, the power source battery can be reduced in size, and therefore virtually no accidents take place in the controlled valve system due to no heat generation in the coil.
