Proportional Directional Valve 4WRZ32W8-360-7X/6EG24N9ETK4/D3M - Bosch Rexroth R900733047

A size 32 valve carrier is bulky anyway and extra pilot lines make it bulkier still. The 4WRZ32W8-360-7X/6EG24N9ETK4/D3M is therefore piloted internally while metering a 360 l/min nominal flow.

Advantages

• Internal pilot oil supply and internal return keep the carrier free of X and Y lines.
• Nominal flow of 360 l/min, up to 1600 l/min total at pressures reaching 350 bar.
• Pressure reducing valve in the pilot stage holds pilot pressure at a fixed level.
• Spool symbol W8, three switching positions on four ports, ISO 4401-10-09-0-05.
• Concealed manual override for commissioning and fault finding.
• Weight of 44.08 kg, NBR seals, external amplifier electronics on 24 VDC.

Applications

The valve is intended for main axes on presses, shears and manipulators. Internal piloting shortens pipework and commissioning. Pressure at port P must cover the pilot demand across the whole cycle.
