Proportional Directional Valve 4WRZ32E1-360-7X/6EG24N9K4/D3V - Bosch Rexroth R900970400

When a power unit already runs its own regulated pilot circuit, the valve should use it rather than tap the main circuit. This size 32 version has external pilot oil supply and external pilot oil return, passes 360 l/min nominal flow and is driven from an external amplifier.

Benefits

• External pilot oil supply and external pilot oil return leave the main circuit untouched
• 360 l/min nominal flow, up to 1600 l/min across the valve
• Spool symbol E1, three switching positions, four ports
• Operating pressure up to 350 bar, integrated pressure reducing valve in the pilot circuit
• ISO 4401-10-09-0-05 port pattern, FKM seals, weight 46 kg

Applications

The valve sits on main cylinders of presses, shears and hoists. It needs an external amplifier card that converts the controller command value into solenoid current. Supply is 24 VDC at a 3-pole (2 + PE) connector.
