SOLENOID OPERATED DIRECTIONAL VALVE

SW-G10 SERIES

FEATURES
• Armature operates in system oil. Impact is decreased and cushioning added, making less noise & solenoid life is prolonged.
• Wet armature solenoid eliminates pushpin 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 3.5 BAR (50 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 piloted.


PORT INTERCONNECTION

• With solenoid "b" energized P-A B-T.
• With solenoid "a" energized P-B A-T.
(But port interconnections are reversed for C3 C5, C6 and C60 type)

ACCESSORIES:

• Mounting bolt kits are supplied with valve socket head cap screws 3/4"-10UNC-2Bx3" L 6 pcs for tightening torque 4730-5850 kgf-cm (4100-5060 lbs-in).
• O-Ring P41 90° 4 pcs and P20 90° 2 pcs.
