Proportional Directional Valve 4WRZE10W6-85-7X/6EG24N9ETK31/A1D3M - Bosch Rexroth R900765029

Anyone metering an axis at 85 l/min nominal flow does not necessarily need a second oil circuit. The 4WRZE10W6-85-7X/6EG24N9ETK31/A1D3M draws pilot oil internally from the main channel, returns it internally and holds control pressure with a built-in pressure reducing valve while the working circuit runs up to 315 bar.

Benefits

• Spool symbol W6 with 3 switching positions and 85 l/min nominal flow in size 10.
• Pilot oil is taken internally and returned internally, so no separate X and Y line is needed.
• The built-in pressure reducing valve holds pilot pressure steady while the main circuit runs up to 315 bar.
• On-board electronics process the ±10 V command value at the valve, powered by 24 VDC through a 7-pole connector (6 + PE) to EN 175201-804.
• Mounting pattern ISO 4401-05-05-0-05, NBR seals for HL fluid, maximum flow 170 l/min, weight 9.12 kg.
• UKCA conformity to SI2016/1091 covering electromagnetic compatibility.

Technical data

Applications

The combination suits feed and lifting axes on presses, injection moulding machines and test rigs where 85 l/min covers the fast traverse. Because pilot supply and return stay inside the valve, a subplate to ISO 4401-05-05-0-05 is enough and no extra X or Y line is required. A concealed auxiliary actuation is fitted.
