MC-S3A Direct Acting Spool, 3 Way 2 Position
DESCRIPTION
7 size, 5/8-18 thread, “Mini” series, solenoid operated, 3 way 2 position, spool valve.
OPERATION
When de-energized the MC-S3A blocks flow at (1) and allows flow from (3) to (2). When energized the
valve allows flow from (1) to (3) and blocks flow at (2).
FEATURES
• Hardened parts for long life.
• Efficient wet-armature construction.
• Cartridges are voltage interchangeable.
• Industry common cavity.
• Unitized, molded coil design.
• Continuous duty rated solenoid.
• Optional coil voltages and terminations.
HYDRAULIC SYMBOL
Operational shift limit 1 GPM (3.8 LPM) from (1) to (3) at 3000
PSI and 2 GPM (7.6 LPM) from (3) to (2) with no load.
For shifted flow performance consult chart.
For higher pressures or flows SEE HC-S3A
