Proportional Directional Valve 4WRZE32W6-360-7X/6EG24N9K31/F1D3M - Bosch Rexroth R901161962

A cooler plus return filter can leave several bar standing in the tank line, enough back pressure to shift the operating point of an internally drained pilot stage. The 4WRZE32W6-360-7X routes pilot oil externally in both directions, holding its nominal flow of 360 l/min at 350 bar clear of that effect.

Benefits

• External pilot oil supply with external drain keeps the pilot circuit fully separated from the tank line.
• 360 l/min nominal flow in size 32, flow up to 1600 l/min.
• 4 to 20 mA current command into on-board electronics running on 24 VDC.
• Spool symbol W6, three switching positions, four ports, pressure reducing valve in the pilot stage.
• 350 bar operating pressure with NBR seals on HL fluid at 44.12 kg.
• ISO 4401-10-09-0-05 interface for subplate mounting, 7-pole connector (6 + PE) to EN 175201-804.

Application

Plants with long return runs, paper machines or large cooling loops among them, benefit from the separated pilot routing. Several consumers sharing one tank line also stay reproducible in their response. Concealed auxiliary actuation allows the axis to be moved when control voltage is lost.
