MA-S2F Pilot Operated Poppet, 2 Way, Normally Closed – Soft Seat
DESCRIPTION
7 size, 5/8-18 thread, “Mini” series, solenoid operated, 2 way normally closed, pilot operated soft seat
poppet valve with reverse flow de-energized.
OPERATION
When de-energized the MA-S2F blocks flow from (1) to (2) and allows free reverse flow from (2) to (1).
When energized the valve allows flow from (1) to (2) and restricts flow from (2) to (1).
FEATURES
• Soft seat for ultra low leakage.
• 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 2.5 GPM (9.5 LPM). For shifted flow
