Proportional Directional Valve 4WRTE27V500L-4X/6EG24K31/F1M - Bosch Rexroth R901110479

Some systems route the return through filters and coolers, and the back pressure rises accordingly. The 4WRTE27V500L-4X/6EG24K31/F1M keeps its pilot circuit away from that, supplies and drains it externally and meters 500 l/min nominal flow with spool symbol V.

Benefits

• External pilot oil supply and external pilot oil return, independent of return pressure.
• 500 l/min nominal flow, maximum flow 1000 l/min, size 27.
• Symbol V in 3 switching positions, operating pressure up to 270 bar.
• 4...20 mA command value on 24 VDC through a 7-pole connector (6 + PE) to EN 175201-804.
• NBR seals, ISO 4401-08-07-0-05 interface, 19.58 kg.

Applications

The valve is used in power units with filter and cooler loops in the return line and in plant with long signal runs. External pilot operation and the current setpoint decouple both disturbances. Mounting is on a subplate to ISO 4401-08-07-0-05.
