MA-S2A Pilot Operated Poppet, 2 Way, Normally Closed
DESCRIPTION
7 size, 5/8-18 thread, “Mini” series, solenoid operated, 2 way normally closed, pilot operated poppet valve
with reverse flow de-energized.
OPERATION
When de-energized the MA-S2A blocks flow from (1) to (2) and allows reverse flow from (2) to (1). When
energized the valve allows flow from (1) to (2) and restricts flow from (2) to (1).
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.
