DESCRIPTION
10 size, 7/8-14 thread, “Delta” series, solenoid operated, 4 way 3 position, Cylinder Spool, proportional directional
valve.
OPERATION
EG-S4P, when de-energized, blocks ow to all ports. When coil (S1) is energized, ow is allowed from (3) to
(4), and from (2) to (1). When coil (S2) is energized, ow is allowed from (3) to (2), and from (4) to (1). Flow is
proportional to the current applied to the coil. A compensator must be used to create a pressure compensated
ow control function.
FEATURES
• Hardened parts for long-life.
• Industry common cavity.
• Excellent linearity and low hysteresis characteristics.
• Cartridges are voltage interchangeable.
• Optional coil voltages and terminations available.
• Unitized, molded coil design.
• Continuous duty rated solenoid.
