Proportional Directional Valve 4WRLE25V1-400P-4X/MPY/24F1 - Bosch Rexroth R901522303

Without a pilot pump the pilot pressure has to come from the working circuit. The 4WRLE25V1-400P-4X/MPY/24F1 taps it internally but drains the pilot oil through a separate external port, while metering 400 l/min nominal flow at up to 350 bar.

Benefits

• Internal pilot oil supply with external pilot oil return, only one extra line needed.
• 400 l/min nominal flow in size 25, 1250 l/min maximum.
• Spool symbol V1, 3 switching positions, linear curve with fine control range.
• 4...20 mA command value on 24 VDC, on-board electronics instead of an amplifier card.
• NBR seals, CE conformity, 19.28 kg, ISO 4401-08-08-0-05 interface.

Applications

This configuration is chosen where several valves share a return line that builds up back pressure. A separate pilot drain keeps switching times repeatable. Typical plant includes presses, lifting gear and medium sized test rigs.
