Proportional Directional Valve 4WRZE32W6-520-7X/6EG24N9EK31/F1D3M - Bosch Rexroth R901048763

On deck or in the engine room, fifty metres of cable between control station plus valve block soon distort a voltage signal. The 4WRZE32W6-520-7X is driven over 4 to 20 mA, producing 520 l/min nominal flow at 350 bar.

Benefits

• 4 to 20 mA current command stays unambiguous over long cable runs, supply 24 VDC.
• Internal pilot oil supply, external drain, leaving only one control line to run outside.
• 520 l/min nominal flow in size 32 at up to 1600 l/min.
• Spool symbol W6 with three switching positions across four ports.
• 350 bar operating pressure, NBR seals, HL hydraulic fluid, 43.96 kg.
• ISO 4401-10-09-0-05 subplate mounting, 7-pole connector (6 + PE) to EN 175201-804.

Application

Winches, hatch or ramp drives plus lifting gear on board are typical consumers at this size. Because the pilot drain runs separately, back pressure in long return lines does not disturb the response. Concealed auxiliary actuation allows the axis to be moved without control current.
