SWH-G04


	SOLENOID OPERATED DIRECTIONAL VALVE SW-G04 SERIES FEATURES • Armature operates in system oil. Impact is decreased and cushioning added, making less noise & prolonged solenoid life. • Wet armature solenoid eliminates push pin seal, reducing seal wear and 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. • Indicating light and bolt kits are standard.

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 100MQ.
• 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 BAR(113 PSI) Valve must be externally drained if there is a possibility of tank line pressure
surges overcoming this differential.
• Open center spools C3, C5, C6 and C60 must be externally drained
• Conforms to IP65

ACCESSORIES:

• Mounting bolt kits are supplied with valve socket head cap screws
2 pieces 1/4"- 20 UNC - 2B x 1- 3/4"L for tightening torque 120-150 kgf-cm (104-130 lbs-in).
4 pieces 3/8" - 16 UNC-2B x 2"L for tightening torque 580-720 kgf-cm (502-624 lbs-in).
• O-ring P22A 4 pieces, P9 2 pieces.
