Proportional Directional Valve 4WRTE32V600L-4X/6EG24K31/A1M - Bosch Rexroth R900954303

An external pilot pressure circuit keeps the pilot stage supplied even when main pressure drops, which is exactly how the 4WRTE32V600L-4X/6EG24K31/A1M is piped. Pilot oil supply along with the drain run externally, while the main spool of symbol V releases 600 l/min nominal flow at 350 bar.

Benefits

• External pilot oil supply, from accumulator or auxiliary pump, so the pilot stage keeps working.
• 600 l/min nominal flow with up to 1600 l/min maximum flow at 350 bar operating pressure.
• Analogue command value +/-10 V, one signal carries direction plus opening degree.
• Spool symbol V, 3 switching positions, 4 ports, linear characteristic.
• On-board electronics, 24 VDC through a 7-pole connector (6 + PE) to EN 175201-804.
• NBR seals for hydraulic fluid HL, mass 37.15 kg, mounting pattern ISO 4401-10-09-0-05.

Applications

This piping suits presses plus test benches with accumulator charging circuits, along with systems whose pump destrokes under partial load. Pilot pressure then stays constant regardless of the working pressure at the axis. Spool position feedback holds the opening degree that was commanded.
