Solenoid valve disc latching refers to when the coil is not energized when the gas circuit is disconnected, and the imported gas solenoid valve latching is when the coil is not energized when the gas circuit is disconnected.

Normally closed two three-way solenoid valve working principle: energize the coil, connected to the gas. When the coil is powered off, the gas circuit is disconnected, which is equivalent to "tapping".

Normally open two three way single electric solenoid valve working principle: the coil is energized, the gas is disconnected, the coil once the power is off, the gas is connected, also known as "point moving type".

Two five-way double electric solenoid valve working principle: when the positive action coil is energized (the positive action coil outlet hole has air), even if the positive action coil is still energized after power, the positive action coil is still energized. When the reaction coil is energized, the reaction gas circuit is connected (the reaction vent is inflated), even if the reaction gas circuit remains energized after the power failure, and before the forward reaction coil is energized. This is tantamount to self-locking. In view of the characteristics of two five-way double electronic solenoid valve, in the design of mechanical and electrical control circuit or writing PLC program, can make the solenoid valve coil work 1~2 seconds, to prevent coil damage.
