Proportional Directional Valve 4WRDE27V1-500L-6X/MXYWG/24A1 - Bosch Rexroth R901545046

A valve of this size has to do two things at once, move a lot of oil, start cleanly on a small signal. Spool symbol V1 gives this size 27 version a finer relation near mid position, at 500 l/min nominal flow, 270 bar operating pressure.

Benefits

• Spool symbol V1 for sensitive travel out of the mid position
• 500 l/min nominal flow, 1000 l/min maximum flow, size 27
• Closed loop on-board electronics, analog command value plus or minus 10 V, 24 VDC supply
• External pilot oil supply, external pilot oil return, leaving the pilot stage clear of pressure surges in the main circuit
• 270 bar operating pressure, NBR seals, 3 switching positions, 4 ports, 19.5 kg
