Proportional Directional Valve 4WRZE10E50-7X/6EG24N9EK31/A1D3M - Bosch Rexroth R900750129

Medium infeed axes needing around 50 l/min are the working range of this valve. The 4WRZE10E50-7X/6EG24N9EK31/A1D3M combines spool symbol E with internal pilot oil pick-up and a separate drain through Y, running on a plus or minus 10 V command at up to 315 bar.

Benefits

• 50 l/min nominal flow with spool symbol E, 4 ports and 3 switching positions.
• Internal pilot oil supply with external drain through Y, so tank pressure does not act on the pilot stage.
• A pressure reducing valve in the pilot stage caps control pressure, working pressure may reach 315 bar.
• The ±10 V command value feeds the on-board electronics directly, supplied with 24 VDC through a 7-pole connector (6 + PE) to EN 175201-804.
• Hole pattern ISO 4401-05-05-0-05 to ISO 4401, NBR seals for HL fluid, 170 l/min maximum flow at 8.43 kg.
• UKCA conformity to SI2016/1091 covering electromagnetic compatibility.

Applications

It is found on machine tools, clamping fixtures and test rigs whose return passes through filters and coolers. The Y drain keeps the pilot stage clear of back pressure. At 8.43 kg the valve can be swapped individually even in crowded manifolds.
