How to operate it?

(When the solenoid valve coil get electricity, 2 hole inlet, 4 hole exhaust. Pneumatic valve actuator

Counterclockwise rotation, open the valve; 

When solenoid valve coil out of electricity, 4 hole inlet, 2 hole exhaust, pneumatic valve actuator clockwise, 

the valve closed. 

Solenoid valve power on, lose electric just can be control the pneumatic valve “on” and “off”. The reversing 

solenoid valve with manual button,when lose electricity, with air source, can be through the manual button on 

the solenoid valve directly control the solenoid valve reversing. 

Also can be match with explosion proof coil. Voltage can be 24vdc, 24vac, 220vac,etc.
