Proportional Directional Valve 4WRZE10E1-85-7X/6EG24N9EK31/A1D3M - Bosch Rexroth R901475526

A pilot circuit that follows system pressure changes the switching time of the main spool. The built-in pressure reducing valve prevents that, and the concealed manual override still allows the axis to be moved without power. Nominal flow is 85 l/min at 315 bar.

Benefits

• Pressure reducing valve in the pilot circuit, holding pilot pressure steady even at 315 bar system pressure.
• Concealed manual override for commissioning and faults without the 24 V DC supply.
• 85 l/min nominal flow, up to 170 l/min maximum flow.
• Internal pilot oil supply, external pilot oil drain, spool symbol E1 with 3 switching positions.
• 8.4 kg weight, NBR seals, ±10 V command value, ISO 4401-05-05-0-05 interface.

Applications

Suited to axes whose system pressure drops sharply within the cycle, for example on presses with a rapid and a pressing stroke. The manual override helps during setup and when freeing the machine after a fault. The external pilot drain keeps the pilot stage clear of tank pressure.
