The 3-2/2 valve is for applications requiring one signal to operate three 2-way normally closed valves simultaneously. A single-solenoid air-pilot operator shifts a spool that opens or closes three sets of supply to ports. Mechanically linked via one spool, all three 2-way functions must shift at the same time and flow rate. Solenoid coils are guaranteed no burnout for the life of the valve.
