Proportional Directional Valve 4WRZE10E50-7X/6EG24N9K31/A1D3M - Bosch Rexroth R900769052

On the 4WRZE10E50-7X/6EG24N9K31/A1D3M pilot stage and main circuit are separated: pilot oil arrives through X and draining runs through Y. The spool of symbol E releases 50 l/min nominal flow and follows the +/-10 V voltage command value up to 315 bar operating pressure. A concealed auxiliary actuation is built in.

Benefits

• External pilot supply and external draining, pilot pressure independent of working pressure.
• 50 l/min nominal flow, maximum flow 170 l/min, operating pressure up to 315 bar.
• Command value +/-10 V, on-board electronics, 24 VDC supply.
• Concealed auxiliary actuation for emergency and set-up operation.
• Spool symbol E, 3 switching positions on 4 ports, mounting pattern ISO 4401-05-05-0-05.
• Weight 8.45 kg, NBR seals, hydraulic fluid HL, UKCA conformity.

Application

The valve is built into plants with central pilot pressure supply in which several axes are fed from the same source. Complete separation keeps control behaviour the same even under changing load pressures. The Y line runs to the tank without back pressure.
