Proportional Directional Valve 4WRZE10W6-50-7X/6EG24N9EK31/F1D3M - Bosch Rexroth R900751838

A control cabinet that drives its axes with current signals needs valves with a matching input. The 4WRZE10W6-50-7X/6EG24N9EK31/F1D3M accepts 4...20 mA, works with spool symbol W6 at 50 l/min nominal flow and drains its pilot stage separately through the Y port.

Benefits

• Spool symbol W6 in size 10, 50 l/min nominal flow across 4 ports.
• 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.
• Command value input 4...20 mA on the on-board electronics, wired through a 7-pole connector (6 + PE) to EN 175201-804 at 24 VDC.
• NBR seals, HL fluid, mounting pattern ISO 4401-05-05-0-05, maximum flow 170 l/min, 8.53 kg weight.
• UKCA conformity to SI2016/1091 covering electromagnetic compatibility.

Applications

The version goes into test rigs, machine tools and handling axes where the return line is pressurised. The 4...20 mA command usually comes straight from an analogue output card in the controller. At 50 l/min there is ample reserve for brisk infeed moves.
