FEATURES
• Armature operates in oil system. Impact is cushioned, noise is reduced and solenoid life is increased.
• Wet armature solenoid eliminates pushpin seal, therefore no seal wear or leakage for longer valve life.
• Molded coils for maximum insulating properties, which is impervious to moisture and dirt.
• Plug-in solenoid, for ease of maintenance.
• All spools and bodies are interchangeable, simplifying maintenance.
• Indicating signal lights and bolt kits are standard.
• High pressure, high flow rating, and low-pressure drop.
• Specially designed, balanced spool allows proper shifting force, for maximum reliability and long life.
• Viton seal kits are available for fire-resistance fluids.
Maximum operating pressure: 310 BAR (4500 PSI)
Rated flow capacity: 63 LPM (16.8 GPM) MAX - Varies by spool type
Maximum tank line back pressure: 138 BAR (2000 PSI)
Maximum frequencies of operation: 300 CPM
Recommended filtration: 25 MICRON

FEATURES
• Suppresses the surge voltage.
• Eliminates sparks between relay contacts.
• Extends the life of the relay contact.
EFFECTS
• Improves the reliability of the control relay.
• Extends the life of conventional relays.
• Can be operated with a miniature relay.
• The RAC rectifier built-in DC model eliminates sparks at the control relay contact. It can be directly operated with a PLC (programmable logic controller).
