At the upper end of size 10 the 4WRZE10E85-7X/6EG24N9TK31/A1D3M delivers 85 l/min nominal flow and accepts its command value as a +/-10 V voltage. Pilot oil comes from an external source while draining runs internally. A concealed auxiliary actuation remains available for the de-energised case.

Benefits

• 85 l/min nominal flow, maximum flow 170 l/min at 315 bar operating pressure.
• External pilot supply, internal draining, which removes the Y line.
• Concealed auxiliary actuation for movement without control voltage.
• Command value +/-10 V, on-board electronics, 24 VDC through a 7-pole connector (6 + PE).
• Spool symbol E, 3 switching positions, 4 ports, mounting pattern ISO 4401-05-05-0-05.
• Weight 8.48 kg, NBR seals, UKCA conformity.

Application

The version is used on fast axes with high volume demand that are fed from a central pilot pressure network. Internal draining requires low back pressure in the tank line. The auxiliary actuation serves commissioning and fault clearance.
