HT-S2B Pilot Operated Poppet, 2 Way Normally Closed
DESCRIPTION
âHigh pressureâ 12 size, 1 1/16-12 thread, âTecnordâ series, solenoid operated, 2 way normally closed, pilot
operated poppet valve with reverse flow energized and de-energized.
OPERATION
When de-energized the HT-S2B 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 from (2) to (1).
FEATURES
x Hardened parts for long life.
x Efficient wet-armature construction.
x Cartridges are voltage interchangeable.
x Industry common cavity.
x Unitized, molded coil design.
x Continuous duty rated solenoid.
x Optional coil voltages and terminations.
