Proportional Directional Valve 4WRZ10E1-50-7X/6EG24N9K4/M - Bosch Rexroth R900955310

A smaller axis does not need a valve at full opening. The 4WRZ10E1-50-7X/6EG24N9K4/M is graded at 50 l/min nominal flow and therefore resolves the command signal more finely, even though 170 l/min are available in the main channel.

Benefits

• 50 l/min nominal flow, matched to axes of moderate oil demand.
• Spool symbol E1, 3 switching positions on the ISO 4401-05-05-0-05 pattern.
• External pilot oil supply and external pilot drain, so pilot pressure can be set separately.
• 315 bar operating pressure at 7.78 kg, subplate mounting in size 10.
• Concealed manual override and NBR seals for HL hydraulic fluid.

Applications

Typical places are positioning axes on presses, injection moulding machines and test rigs where speed comes from an amplifier. The graded nominal flow keeps the characteristic curve in the usable range instead of packing much of the stroke into a few percent of command signal. Wiring runs through a 7-pole (6 + PE) plug to EN 175201-804.
