Proportional Directional Valve 4WRKE32W6-600P-3X/6EG24EK31/A1D3M - Bosch Rexroth R901026641

High tank back pressure shifts the characteristic curve of a pilot-operated valve. The 4WRKE32W6-600P-3X/6EG24EK31/A1D3M avoids that with a separate pilot oil drain, supplies itself internally and controls 600 l/min nominal flow at up to 350 bar.

Benefits

• Internal pilot oil supply with external pilot oil return, switching times independent of tank pressure.
• 600 l/min nominal flow, maximum flow 1600 l/min in size 32.
• ±10 V command value on 24 VDC, on-board electronics with spool position feedback.
• Spool symbol W6 in 3 switching positions, linear curve with fine control range.
• NBR seals, ISO 4401-10-09-0-05 interface, 36.74 kg.

Applications

The valve works on presses and lifting gear whose return line collects several actuators. Only the pilot drain line has to be added, a dedicated pilot pump is not needed. That keeps the effort low when an existing system is rebuilt.
