Directional Spool Valve 4WEH32L6X/6EG24N9K4 - Bosch Rexroth R901030477

The 4WEH32L6X switches oil direction for actuators moved at 1100 l/min. At 280 bar operating pressure the pilot stage supplies the shifting force that a directly actuated solenoid of this size could not produce.

Benefits

• Rated flow up to 1100 l/min in size 32, operating pressure up to 280 bar
• Three switching positions to symbol L across four ports
• External pilot oil supply and external pilot oil return, so the pilot stage is fed independently of the main circuit
• Solenoid actuation at 24 VDC, 3-pole (2 + PE) connector to EN 175301-803
• Subplate mounting to ISO 4401-10-09-0-05, weight 35.32 kg

Applications

Valves of this class sit on hydraulic presses, forging lines and injection moulding machines where a stroke has to finish within seconds. External pilot supply pays off when the main circuit runs unpressurised and the pilot stage still needs pressure. The centre position holds the actuator still between strokes.
