Proportional Directional Valve 4WRZ10W8-85-7X/6EG24N9EK4/V - Bosch Rexroth R900963068

On the 4WRZ10W8-85-7X/6EG24N9EK4/V pilot oil is picked up internally and drained through a separate line. Nominal flow is 85 l/min and total flow reaches 170 l/min.

Advantages

• Internal pilot oil supply with external pilot oil return, so back pressure in the tank does not disturb piloting.
• Nominal flow of 85 l/min at operating pressure up to 315 bar.
• Symbol W8 in three switching positions, size 10 to ISO 4401-05-05-0-05.
• Concealed manual override and control through external electronics.
• FKM seals, weight 7.75 kg.

Application

Where back pressure builds up in the tank passage, for instance through filters or coolers, a separate pilot oil return helps. The valve then keeps controlling evenly. It is used in presses, test rigs and forming technology.
