Proportional Directional Valve 4WRZ10E1-85-7X/6EG24N9ETK4/M - Bosch Rexroth R900977990

The fewer lines a manifold needs, the fewer sealing points arise. This valve therefore feeds and returns pilot oil internally. The main spool works to symbol E1 at a nominal flow of 85 l/min, with 170 l/min possible at maximum.

Benefits

• Internal pilot oil supply and internal pilot oil return, fewer sealing points on the manifold
• Symbol E1 in 3 switching positions across 4 ports
• Nominal flow 85 l/min, maximum flow 170 l/min
• Concealed auxiliary actuation that stays protected against adjustment in service
• Operating pressure up to 315 bar, subplate mounting to ISO 4401-05-05-0-05
• NBR seals for HL hydraulic fluid, mass 7.78 kg

Applications

The valve is used on feed and lifting axes that can be piloted from the main circuit. The command signal comes from external electronics that can be matched to the axis.
