Proportional Directional Valve 4WRZ10W9-85-7X/6EG24N9ETK4/D3V - Bosch Rexroth R978917803

Stepless motion profiles need a valve whose opening follows the command signal. The 4WRZ10W9-85-7X/6EG24N9ETK4/D3V works proportionally, is rated at 85 l/min nominal flow and permits a maximum of 170 l/min at 315 bar.

Benefits

• 85 l/min nominal flow and up to 170 l/min maximum flow in size 10
• Operating pressure up to 315 bar with FKM seals, suited to higher oil temperatures
• Electrical control with external electronics, leaving the choice of amplifier open
• Symbol W9 with three switching positions on four ports
• Pilot-operated with internal pilot oil supply and internal pilot oil return
• 8.34 kg mass, pattern ISO 4401-05-05-0-05

Application

The valve controls feed and positioning axes where speed and direction are set steplessly. Control runs through external amplifier electronics that have to match the valve. FKM seals have to be considered when choosing the fluid.
