TT-S2C PILOT OPERATED POPPET, 2 WAY NORMALLY OPEN
DESCRIPTION
12 size, 1 1/16-12 thread, “TWELVE” series, solenoid operated, 2 way normally open, pilot operated poppet valve
with free reverse ow energized.
OPERATION
When de-energized the TT-S2C allows ow to pass from (1) to (2), but restricts ow from (2) to (1).
When energized the valve blocks ow from (1) to (2) but allows free reverse ow from (2) to (1).
OPERATION OF MANUAL OVERRIDE OPTION: to override, turn the manual override screw clockwise.
To release turn the manual override screw counterclockwise.
FEATURES
• Hardened parts for long life.
• Efcient wet-armature construction.
• Cartridges are voltage interchangeable.
• Manual override option.
• Industry common cavity.
• Unitized, molded coil design.
• Continuous duty rated solenoid.
• Optional coil voltages and terminations.
• Optional “I” Coil: Weatherproof, Thermal Shock, Immersion Safe.
