Proportional Directional Valve 4WRZE32W6-360-7X/6EG24N9EK31/A1D3M - Bosch Rexroth R901279685

Space for piping is short on a compact hydraulic power unit, so every control line saved shortens assembly. The 4WRZE32W6-360-7X takes pilot oil internally from the pressure port yet drains it externally while controlling a nominal flow of 360 l/min at 350 bar.

Benefits

• Internal pilot oil supply removes the extra feed line, with pilot oil drained externally.
• 360 l/min nominal flow in size 32, flow up to 1600 l/min possible.
• ±10 V command on 24 VDC straight into the on-board electronics, no separate amplifier card.
• Spool symbol W6, three switching positions, four ports, concealed auxiliary actuation.
• 350 bar operating pressure with NBR seals on HL fluid, 43.94 kg.
• Subplate mounting to ISO 4401-10-09-0-05, wired through a 7-pole connector (6 + PE) to EN 175201-804.

Application

It suits injection moulding machines or clamping systems where the valve stand sits right on the tank with little room for control lines. Draining pilot oil externally keeps the pilot stage clear of back pressure built up by filters or coolers in the return line. At 360 l/min the valve covers mid-sized axes without moving the manifold to the next frame size.
