Proportional Directional Valve 4WRZE10W9-85-7X/6EG24N9K31/A1D3M - Bosch Rexroth R901057127

A pressure reducing valve in the pilot stage holds pilot pressure within its band even while working pressure swings. The size 10 proportional directional valve meters 85 l/min nominal flow at up to 315 bar operating pressure and weighs 9.16 kg.

Benefits

• Pressure reducing valve in the pilot stage, pilot oil supply and return routed externally
• 85 l/min nominal flow, maximum flow 170 l/min, maximum operating pressure 315 bar
• Spool symbol W9 with 3 switching positions across 4 ports, concealed auxiliary actuation on the valve
• Analog command value ±10 V into the on-board electronics, supply voltage 24 VDC
• NBR seals for HL hydraulic fluid, UKCA conformity to SI2016/1091, weight 9.16 kg

Applications

Presses, hoists and transfer axes with frequent reversals are the usual cases. A separate source has to be provided for pilot oil supply and return. The mounting pattern follows ISO 4401-05-05-0-05, connection is made through a 7-pole connector (6 + PE) to EN 175201-804.
