Structural features:
Action responsive; emissions from large
Body hot forging molding process, appearance
With original sealing material, ten times the life of similar products
CNC machining, to ensure the accuracy and reliability of the solenoid valve
Authoritarian coil, and a structured way of cooling, easily burned;
Stop operation for a long time to restart, the action also sensitive
working principle
Dual pilot solenoid pilot valve structure having a mechanical self-locking memory function self-holding type. When the coil member "B" is energized, the solenoid valve is opened, then off, then the solenoid valve is a normally-on state, when the component coil "A" is energized, the solenoid valve is closed, then power off, when the solenoid valve is normally closed. If the coil "A", "B" is energized at the same time, when the solenoid valve is a normally-on state, the coil will not result in burnout. This valve can be applied to the next switching cycle longer than the work environment.
