Proportional Directional Valve 4WRZ10E1-50-7X/6EG24K4/M - Bosch Rexroth R901467283

A replacement valve only counts as one if the pilot oil path fits too. The 4WRZ10E1-50-7X/6EG24K4/M combines spool symbol E1 with 50 l/min nominal flow, external pilot supply and external pilot drain, at 315 bar operating pressure.

Benefits

• Spool symbol E1 at 50 l/min nominal flow in size 10.
• Pilot oil in and out externally, suited to manifolds with their own pilot supply.
• 315 bar operating pressure on the ISO 4401-05-05-0-05 pattern.
• 8.48 kg, subplate mounting with 4 ports and 3 switching positions.
• 24 VDC through external electronics, 7-pole (6 + PE) plug to EN 175201-804, NBR seals for HL hydraulic fluid.

Applications

The valve belongs in manifolds of presses, machine tools and test rigs that run their own pilot circuit. It turns the analogue command value of the higher-level electronics into a proportional opening, so acceleration and braking follow the ramp of the control system. For maintenance what counts is that spool symbol, flow rating and pilot variant match the unit being replaced.
