Proportional Directional Valve 4WRZ10E85-7X/6EG24ETK4/D3M - Bosch Rexroth R901121111

A constant pilot pressure makes the behaviour of a proportional valve repeatable. This version achieves it with a built in pressure reducing valve and drives the main spool to symbol E. At a nominal flow of 85 l/min, 170 l/min flow at maximum.

Benefits

• Symbol E in 3 switching positions at a nominal flow of 85 l/min
• Pressure reducing valve in the pilot stage for consistent switching behaviour
• Maximum flow 170 l/min at an operating pressure of up to 315 bar
• Internal pilot oil supply and internal pilot oil return
• Driven from external electronics to EN 175201-804
• NBR seals for HL hydraulic fluid, mass 8.2 kg

Applications

The valve is used on feed axes, lifting gear and test cylinders where motion follows the command signal. The stable pilot pressure helps when changing loads act in the main circuit.
