Proportional Directional Valve 4WRTE27V1-500L-4X/6EG24TK31/A1M - Bosch Rexroth R901538052

Between size 25 and size 32 sits size 27, and that is exactly where this valve belongs. The 4WRTE27V1-500L-4X/6EG24TK31/A1M meters 500 l/min nominal flow at up to 270 bar operating pressure, follows a ±10 V voltage setpoint and takes its pilot oil from an external port.

Benefits

• 500 l/min nominal flow in size 27, maximum flow 1000 l/min.
• Operating pressure up to 270 bar, ISO 4401-08-08-0-05 interface.
• External pilot oil supply with internal pilot oil return, only one extra line.
• ±10 V command value on 24 VDC, on-board electronics with spool position feedback.
• Spool symbol V1, 3 switching positions, NBR seals, 19.4 kg.

Applications

The valve controls main and secondary axes on presses, injection moulding machines and test rigs whose system pressure stays below 270 bar. At 500 l/min it remains fast on large cylinders without needing size 32. An external pilot pressure has to be available in the system.
