The SO3L is a 3/8" NPTF side ported, 2 position, spring return, solenoid operated valve
with a dust excluder nut on the solenoid exhaust. The spool is shifted by 50 to 160 psi
internal pilot air derived from pressure in port 1 when the solenoid is energized. 50 to
160 psi must be maintained on port 1 to keep the spool shifted while the coil is energized.
The spool is spring returned when the solenoid is de-energized. Standard voltage is 120/60,
indicate other voltages (i.e. 12VDC, 24VDC, 240/60 etc.).
