Proportional Directional Valve 4WRZE10W6-85-7X/6EG24N9EK31/F1D3M - Bosch Rexroth R900961306

On the 4WRZE10W6-85-7X/6EG24N9EK31/F1D3M the spool of symbol W6 releases up to 85 l/min nominal flow, while pilot oil comes internally from port P and drains externally through Y. The 4...20 mA current command value controls up to 315 bar operating pressure. A concealed auxiliary actuation supplements the control.

Benefits

• 85 l/min nominal flow, maximum flow 170 l/min, operating pressure up to 315 bar.
• Internal supply from P and external draining through Y, pilot pressure free of return back pressure.
• Current command value 4...20 mA, on-board electronics, 24 VDC supply.
• Concealed auxiliary actuation for emergency and maintenance movement.
• Spool symbol W6, 3 switching positions on 4 ports, ISO 4401-05-05-0-05.
• Weight 8.48 kg, NBR seals, hydraulic fluid HL, UKCA conformity.

Application

The valve is used on fast axes in plants without their own pilot pressure network whose return line is nevertheless heavily loaded. External draining keeps the pilot stage free of those fluctuations. Port P must be under permanent pressure.
