3-Way Normally Closed Single
Solenoid Operation
• Solenoid De-energized: Flow is from port 2
to port 3. Port 4 is open to exhaust port 3
(breather function); pressure port 1 is closed.
Slight pilot exhaust is also apparent. Port 5
is not used.
• Solenoid Energized: Flow is from pressure
port 1 to port 2. Port 4 is open to exhaust port
3 (breather function); pilot exhaust is closed.
3-Way Single Solenoid (3/2)
4-Way Single Solenoid Operation
• Solenoid De-energized: Flow is from pres-
sure port 1 to port 4 and from port 2 to port
3. Port 5 is closed. Slight pilot exhaust is
also apparent.
• Solenoid Energized: Flow is from pressure
port 1 to port 2 and from port 4 to port 5. Port
3 and pilot exhaust are closed.
4-Way Single Solenoid (5/2)
Dual Solenoids: Solenoid may be energized mo-
mentarily or continuously depending upon ap-
plication. Dual solenoid valves are used where
equipment must not change position when elec-
trical power fails. Valve operates when one so-
lenoid is energized and returns when the other
solenoid is energized.
CAUTION
Do not energize solenoids A and B simultane-
ously, as this will cause valve to malfunction.
NOTE: Minimum on time for each solenoid is
0.3 seconds.
3-Way Normally Closed Dual
Solenoid Operation
• Solenoid A Last Energized: Flow is from
pressure port 1 to port 2. Port 4 is open to ex-
haust port 3 (breather function). Slight pilot
exhaust is apparent when solenoid A is de-
energized. Port 5 is not used.
• Solenoid B Last Energized: Flow is from
pressure 2 to port 3. Port 4 is open to ex-
haust 3 (breather function); pressure port 1 is
closed. Slight pilot exhaust is apparent when
solenoid B is de-energized.
