Double acting pneumatic butterfly valve with double coil solenoid valve Working principle

Double acting pneumatic valve with 2/5 way double coil solenoid valve working principle,

Double electric control solenoid valve on both sides by electromagnetic coil electricity and without electricity to control the valve opening and closing, when one coil power -loosing, another coil without electricity can keep valve core at the current position, and this current position is called a memory function of the valve.

1 hole: Air source inlet hole, 5KG

2 hole: Connect with pneumatic valve 2 hole

4 hole: Connect with pneumatic valve 4 hole

3 hole, 5 hole: Corresponding to 2 hole, 4 hole exhaust.

When solenoid valve A coil get electricity, 2 hole inlet air, 4 hole exhaust. Pneumatic valve actuator counterclockwise rotation, valve open. When A coil power off, B coil without electricity, pneumatic valve is still keep the current position. A coil just need get once electricity and open the valve Coil with low power consumption.

When solenoid valve B coil get electricity, 4 hole inlet, 2 hole exhaust. Pneumatic valve actuator clockwise rotation, valve closed. When B coil power off, A coil without electricity, pneumatic valve still keep the current position, B coil just need get once electricity, valve closed, the coil with low power consumption.

If A coil and B coil get electricity at the same time, the valve not working, remain in place.
