HE-S2B 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 energized and de-energized.
OPERATION
When de-energized the HE-S2B acts as a check valve, allowing flow to pass from (2) to (1), while blocking
flow from (1) to (2). When energized the valve opens allowing flow to pass from (1) to (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.
• Optional “I” Coil: Weatherproof, Thermal Shock, Immersion Safe.
HYDRAULIC SYMBOL
Uses “L” Coil.
