Proportional Directional Valve 4WRZ10E1-85-7X/6EG24N9ETK4/V - Bosch Rexroth R900974051

The 4WRZ10E1-85-7X/6EG24N9ETK4/V feeds its pilot stage from its own circuit and drains pilot oil internally. It controls 85 l/min nominal flow to symbol E1 at a total flow of up to 170 l/min.

Advantages

• Internal pilot oil supply and internal pilot oil return, so X and Y lines are not needed.
• Nominal flow of 85 l/min in size 10.
• Symbol E1 with three switching positions at up to 315 bar operating pressure.
• Concealed manual override, version without pressure reducing valve.
• FKM seals for HL hydraulic fluid, weight 7.74 kg.

Application

A block layout without extra pilot lines saves drillings and sealing points. The valve controls axes in machine tools, presses and handling equipment. It requires a system pressure that stays high enough for piloting at all times.
