Proportional Directional Valve 4WRZE32W6-520-7X/6EG24ETK31/A1D3M - Bosch Rexroth R900954704

Reusing an existing size 32 subplate rarely leaves separate pilot oil ports available. The 4WRZE32W6-520-7X/6EG24ETK31/A1D3M therefore takes pilot oil supply and return internally while metering 520 l/min nominal flow at 350 bar.

Benefits

• Internal pilot oil supply and internal return - the main subplate ports are enough, no extra piping.
• 520 l/min nominal flow with a maximum flow of 1600 l/min.
• 350 bar operating pressure, symbol W6, three switching positions, four ports.
• Pilot pressure held by a built-in pressure reducing valve, independent of main stage load pressure.
• ±10 V command value on on-board electronics, 24 V DC supply through a 7-pole connector (6 + PE).
• 43.96 kg weight, ISO 4401-10-09-0-05 subplate interface, NBR seals.

Application

This version fits conversions on presses, injection moulding machines and lifting gear where the existing subplate has to stay in place. Keeping the pilot circuit internal cuts the number of fittings and with it the leakage risk. It does require an operating pressure that reliably supplies the pilot stage.
