Proportional Directional Valve 4WRZE32E1-520-7X/6EG24N9EK31/A1D3M - Bosch Rexroth R901502606

On cylinders with very large swept volume the pilot circuit decides whether the axis runs smoothly. The 4WRZE32E1-520-7X/6EG24N9EK31/A1D3M carries its own pressure reducing valve in the pilot stage while controlling 520 l/min nominal flow at 350 bar.

Benefits

• 520 l/min nominal flow in size 32, rated to a maximum flow of 1600 l/min.
• Pressure reducing valve in the pilot stage keeps pilot pressure steady, internal pilot oil supply with external pilot oil return.
• Analog ±10 V command value into the on-board electronics, 24 VDC supply through a 7-pole connector (6 + PE).
• Symbol E1 with 3 switching positions across 4 ports, concealed manual override for commissioning.
• UKCA conformity to SI2016/1091, 43.6 kg, subplate mounting to ISO 4401-10-09-0-05.

Application

This size targets forging presses, continuous casting lines as well as large test cylinders that move several hundred litres per minute. The external pilot oil return keeps the pilot stage clear of main circuit tank pressure, which matters on long return lines. Symbol E1 leaves the centre position clearly defined.
