Binary :(zc2/32) pneumatic double solenoid valve coil is energized, the media inlet end of a channel (2) open, the second channel (3) closed; When the solenoid valve coil power, the media inlet end of a channel (2) closed, the second channel (3) open; (Check valve must be installed before the two inlet ends of the internal valve)

Outgoing line: normally closed (ZC2/3)- in the power state, interface 2 to interface 1, interface 3 closed; In the power off state, interface 2 is closed, and interface 1 leads to interface 3. In power-on state, interface 3 leads to interface 1, interface 2 to interface 2, and interface 3 to interface 2. In the power-on state, interface 3 leads to interface 2 and interface 1 to interface 2.

1-1-1: normally closed: when the new solenoid valve coil is energized, 2 leads 1,1 and 3 are closed. In the event of a power outage, both 2 and 1 are off, with 1 leading to 3. Normally open type: coil startup, 3,1 off,1 lead. In case of coil power failure, close 3 wires of 1.1 and 2.
