Proportional Directional Valve 4WRDE27V500L-6X/MXYWG/24A1 - Bosch Rexroth R901554712

Around 500 l/min it is main spool sensitivity that decides cycle time as well as surface quality. This pilot operated proportional directional valve in size 27 runs the linear spool symbol V, passes up to 1000 l/min, is rated at 270 bar operating pressure.

Benefits

• 500 l/min nominal flow, 1000 l/min maximum flow from a size 27 body
• Spool symbol V with a linear characteristic, keeping command value against speed evenly matched over the whole travel
• On-board electronics with closed loop spool control, analog command value plus or minus 10 V on 24 VDC, no external amplifier
• External pilot oil supply, external pilot oil return, so pilot behaviour stays clear of the main circuit
• 270 bar operating pressure, NBR seals, HL hydraulic fluid, ISO 4401-08-08-0-05 connection diagram, 19.5 kg

Application

Typical places of work are large presses, injection moulding machines, test benches with fast cylinders of large area. Because pilot supply as well as pilot drain are external, the pilot stage can run on its own filtered circuit. Mounting is on a subplate to ISO 4401-08-08-0-05 with 4 ports.
