Proportional Directional Valve 4WRZ10E1-85-7X/6EG24N9EK4/M - Bosch Rexroth R900977454

This version takes pilot oil from the main circuit and discharges it through a dedicated port. Back pressure in the return line therefore has no effect on the pilot stage. The main spool works to symbol E1 at a nominal flow of 85 l/min.

Benefits

• Internal pilot oil supply with external pilot oil return
• Symbol E1 in 3 switching positions across 4 ports
• Nominal flow 85 l/min, maximum flow 170 l/min
• Concealed auxiliary actuation for commissioning and fault finding
• Operating pressure up to 315 bar, subplate mounting to ISO 4401-05-05-0-05
• NBR seals for HL hydraulic fluid, mass 7.72 kg

Applications

The valve suits systems whose return line runs through coolers and filters and therefore carries pressure. The main circuit supplies the required pilot pressure at the same time.
