Proportional Directional Valve 4WRKE32W8-600L-3X/6EG24EK31/F1D3M - Bosch Rexroth R901093095

In sprawling plants the control cabinet often sits dozens of metres away from the power unit. This pilot-operated proportional directional valve in size 32 therefore accepts an impressed current command value of 4-20 mA to meter 600 l/min of nominal flow under closed-loop spool control, at a maximum operating pressure of 350 bar.

Benefits

• A 4-20 mA command value stays immune to interference over long cables, a broken wire shows as zero current
• Spool symbol W8 with linear characteristic curve for 600 l/min nominal flow, peaks reach 1600 l/min
• Internal pilot oil supply saves the separate pilot line, the return remains externally routed
• Operating pressure to 350 bar across 3 switching positions with 4 ports to ISO 4401-10-09-0-05
• On-board electronics on 24 VDC with internal spool position feedback, wired through a 7-pole connector
• NBR seals suit HL hydraulic fluid, installed mass 36.92 kg

Application

Suited to press lines, test rigs and steelworks drives with a remote control room. The current signal bridges cable distances where a ±10 V command value already drifts visibly. Internal pilot supply cuts the piping on the manifold down to the pilot oil return.
