Proportional Directional Valve 4WRZE10W6-50-7X/6EG24N9ETK31/F1V - Bosch Rexroth R900979444

In hot forming, hydraulics sit close to induction coils and converters, and oil temperature rarely stays low. The 4WRZE10W6-50-7X/6EG24N9ETK31/F1V answers both points through a 4...20 mA current command and FKM seals, metering 50 l/min nominal flow at up to 315 bar.

Benefits

• 4...20 mA command value, resistant to electromagnetic interference.
• FKM seals, suited to HL hydraulic fluid at elevated temperature.
• 50 l/min nominal flow, maximum flow 170 l/min in size 10.
• Internal pilot oil supply and internal pilot oil return, 8 kg weight.
• Spool symbol W6, operating pressure up to 315 bar, connection diagram ISO 4401-05-05-0-05.
• On-board electronics fed by 24 VDC through a 7-pole (6 + PE) connector to EN 175201-804.

Technical data

Applications

The valve is found on forging manipulators, hot forming presses and stretch reducing mills. Its 50 l/min cover infeed and clamping motion while the main drive runs off a larger circuit. Concealed auxiliary actuation helps during set-up while the control system is still offline.
