Proportional Directional Valve 4WRDE16V1-220L-6X/MXTWG/24A5 - Bosch Rexroth R901557075

In power units with a separate pilot supply the valve has to match the existing circuit. The 4WRDE16V1-220L-6X/MXTWG/24A5 is piloted externally and releases pilot oil internally, works in size 16 with 220 l/min nominal flow and withstands operating pressures up to 350 bar.

Benefits

• External pilot oil supply with internal pilot oil return matches power units that carry their own pilot pump.
• 220 l/min nominal flow in size 16, with 460 l/min as the maximum flow of the range.
• Symbol V1 with three switching positions and internal spool position feedback.
• Command value ±10 V DC, supply 24 V DC through a 7-pole connector (6 + PE) to EN 175201-804.
• NBR seals for HL mineral oil, weight 10.5 kg, mounting pattern ISO 4401-07-07-0-05.

Technical data

Applications

The valve controls main axes in presses, lifting gear and clamping systems that already run a dedicated pilot circuit. Because the pilot return is routed internally, no extra drain line to tank is needed. At 220 l/min there is still reserve for short rapid traverse phases.
