Proportional Directional Valve 4WRZ32W8-360-7X/6EG24N9EK4/D3M - Bosch Rexroth R900703652

When the tank gallery carries counter pressure but the plant has no pilot pressure source of its own, this combination is the right one. The 4WRZ32W8-360-7X/6EG24N9EK4/D3M feeds itself internally and returns pilot oil externally at a 360 l/min nominal flow.

Advantages

• Internal pilot oil supply from P, no separate pilot pressure source required.
• External return through Y, independent of counter pressure in the tank gallery.
• Nominal flow of 360 l/min, up to 1600 l/min total flow.
• Pressure reducing valve in the pilot stage, operating pressure up to 350 bar.
• Spool symbol W8, three switching positions, ISO 4401-10-09-0-05, concealed manual override.
• Weight of 43.9 kg, NBR seals, external amplifier electronics on 24 VDC.

Applications

The version is intended for systems with return filters, coolers or a shared tank gallery. It works without an extra pilot pump as long as pressure at P covers the pilot demand. Port Y has to be provided on the manifold.
