HE-S2A Pilot Operated Poppet, 2 Way Normally Closed
DESCRIPTION
“High Pressure”10 size, 7/8-14 thread, “Delta” series, solenoid operated, 2 way normally closed, pilot
operated poppet valve with reverse flow de-energized.
OPERATION
When de-energized the HE-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.
• Optional “I” Coil: Weatherproof, Thermal Shock, Immersion Safe.
HYDRAULIC SYMBOL
Uses “L” Coil.
