Proportional Directional Valve 4WRZ10W8-85-7X/6EG24N9K4/V - Bosch Rexroth R901216110

On the 4WRZ10W8-85-7X/6EG24N9K4/V both pilot oil supply and pilot oil return sit outside the valve. At 85 l/min nominal flow it controls larger axes in size 10.

Advantages

• External pilot oil supply and external pilot oil return, keeping piloting free of load pressure.
• Nominal flow of 85 l/min, total flow up to 170 l/min.
• Symbol W8 in three switching positions, operating pressure up to 315 bar.
• Concealed manual override for commissioning and testing.
• Connection diagram ISO 4401-05-05-0-05, FKM seals, weight 7.78 kg.

Application

When load pressure collapses during the cycle, a dedicated pilot circuit keeps valve dynamics steady. Such circuits are found in presses, roll adjustment drives and test equipment. The command value comes from external amplifier electronics.
