SOLENOID CONTROLLED PILOT OPERATED DIRECTIONAL VALVE
SW-G04 SERIES
FEATURES
Armature operates in system oil. Impact is decreased and cushioning
added, making noise lowered & solenoid life Prolonged.
Wet armature solenoid eliminates push pin seal, reducing seal wear or
leakage for longer valve life.
Molded coil gives maximum insulating properties. They are protected by
a special resin and impervious to moisture and dirt for ease of
maintenance.
Plug-in solenoid, easy to change coil.
Change of pilot and drain can be easily accomplished by plugging or
unplugging.
Spool is designed to avoid creating jet flow or turbulence under high
pressure and flow.

TECHNICAL DATA:
Solenoid can be used within − 10% to + 10% of the rated voltage of the coil.
Withstand voltage 1500 v/sec.
Insulation resistance over 100MΩ.
A momentary signal of approx 0.1 second is required for shifting action.
Pilot pressure of internally drained valves must always exceed tank port pressure by a minimum of 8.0 kgf/cm
2
(113 PSI)
Valve must be externally drained if there is a possibility of tank line persuader surges overcoming this differential.
Open center spools C3, C5, C6, C60 must be externally piloted.
ACCESSORIES:
Mounting bolt kits are supplied with valve socket head cap screws
M6 x 45 L 2 pieces (1/4"− 20 UNC − 2B x 1 3/4"L) for tightening torque 120-150 kgf-cm.(104-130 lbs-in).
M10 x 50 L 4 pieces (3/8" − 16 UNC-2B x 2"L) for tightening torque 580-720 kgf-cm.(502-624 lbs-in).
O-ring P22A 90° 4 pieces, P9 90 ° 2 pieces.
