Proportional Directional Valve 4WRZ32E1-360-7X/6EG24N9K4/M - Bosch Rexroth R900707465

Test rigs often run a small, finely filtered pilot circuit, because the pilot stage reacts to contamination more sharply than the main spool. The 4WRZ32E1-360-7X/6EG24N9K4/M fits that, since pilot oil is fed in and drained externally, at 360 l/min nominal flow.

Benefits

• External supply and external return of pilot oil, the pilot stage can be fed from a separate filtered circuit.
• 360 l/min nominal flow, up to 1600 l/min throughput in size 32.
• Spool symbol E1 across 3 switching positions over 4 ports to ISO 4401-10-09-0-05.
• 350 bar maximum operating pressure, 43.4 kg weight using NBR seals for HL fluid.
• Concealed auxiliary actuation, the hydraulic side can be checked separately from the electronics.

Applications

The valve is used on hydraulic test rigs, materials testing machines with large cylinders and experimental setups whose circuitry changes. Separate pilot routing allows filtration grade and pilot pressure to be defined independently. An external amplifier at 24 VDC provides the command signal.
