Proportional Directional Valve 4WRZ32W6-520-7X/6EG24N9EK4/M - Bosch Rexroth R900249353

Where no pilot pump is available but the return carries back pressure, internal supply with external relief is the fitting combination. The 4WRZ32W6-520-7X/6EG24N9EK4/M implements it and controls 520 l/min nominal flow.

Benefits

• Pilot oil supplied internally, drained externally, no pilot pump, own relief line.
• 520 l/min nominal flow, spool symbol W6, size 32.
• 350 bar maximum operating pressure, peaks up to 1600 l/min.
• Concealed auxiliary actuation for setup work.
• 42.4 kg weight, NBR seals, subplate mounting to ISO 4401-10-09-0-05.

Applications

The valve is used on presses and lifting gear with long collecting returns. External relief keeps the pilot stage free of back pressure in the tank channel. Replacement goes against units of the same pilot variant.
