NFPA D10 (SW-G10)

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.

PRESSURE DROP AND PERFORMANCE CURVES


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.
• If the hydraulic circuit does not provide sufficient pilot pressure to shift valves with open center spool configurations C3, C5, C6, do either: (1) Use the external pilot option ("-E-"). Provide 140 PSI (10 Bar) minimum pilot pressure to the "X” port on the manifold or subplate from another source in your system to shift the valve. (2) If the valve must be internally piloted in your system, then install back pressure of 140 PSI (10 Bar) minimum at the tank line of the main valve. The valve must be externally drained ("-T-") with this method.

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.
