Working principle

ZCRH series globe valve is often open type pulse electromagnetic valve, has triggered self-locking and manual reset accident.

1, cut and in daily work is often a state, magnetic coil in short, don't consume energy state of opening.

2, when the accident occurs, the globe valve, trigger instant electrified wire fast closure, cut-off valve will be open again.

3, then through air, artificial to reset the pole, hear shuthelah up a "MAO" that has been opened, loosen the valve, the valve will cut open, and restore gas.
