Proportional Directional Valve 4WRZE32E1-520-7X/6EG24N9ETK31/A1M - Bosch Rexroth R901170019

The less pipework hanging off a valve block, the faster it goes together and the less there is to leak. This size 32 variant runs entirely on internal pilot oil while controlling 520 l/min nominal flow at up to 350 bar.

Key benefits

• Internal pilot oil supply and internal pilot oil return, no pipework beyond the 4 main ports
• 520 l/min nominal flow in a size 32 body with 1600 l/min of headroom
• Command value ±10 V into the on-board electronics, 24 V DC supply
• Operating pressure up to 350 bar, spool symbol E1, 3 switching positions
• At 43.25 kg one of the lighter builds in the series

Applications

Aimed at compact valve blocks in presses and plastics machinery where there is no room left for pilot lines. System pressure has to stay above the minimum pilot pressure during reversal. The tank port may only carry low back pressure.
