Proportional Directional Valve 4WRZE10E50-7X/6EG24N9K31/A1D3V - Bosch Rexroth R901378712

If system pressure swings over the cycle, the timing of the pilot stage changes with it. The 4WRZE10E50-7X/6EG24N9K31/A1D3V therefore receives control oil through X from a separate circuit, drains through Y and controls 50 l/min nominal flow.

Benefits

• External pilot oil supply and external return for a constant control pressure independent of working pressure.
• 50 l/min nominal flow in size 10 against a series maximum flow of 170 l/min.
• Spool symbol E, 3 switching positions, 4 ports, integrated pressure reducing valve.
• Plus or minus 10 V command, 24 VDC supply through a 7-pole connector (6 + PE) to EN 175201-804.
• FKM seals, operating pressure up to 315 bar, weight 8.48 kg, UKCA conformity.

Applications

Valves of this kind work on test rigs, on simulators and on axes with accumulator supply. The separate control circuit keeps switching time equal across the whole cycle. 50 l/min nominal flow suits cylinders of medium area on a short stroke.
