Proportional Directional Valve 4WRZ16W8-125-7X/6EG24N9TK4/D3M - Bosch Rexroth R901470378

Where an axis has to start gently and come to a controlled stop, plain switching is not enough. The 4WRZ16W8-125-7X/6EG24N9TK4/D3M meters oil continuously and is rated at 125 l/min nominal flow in size 16.

Benefits

• 125 l/min nominal flow, 460 l/min maximum flow.
• Operating pressure up to 350 bar, NBR seals for HL hydraulic fluid.
• 3 switching positions to spool symbol W8 across 4 ports.
• Driven by external electronics, solenoid supply 24 V DC.
• Integrated pressure reducing valve keeps pilot pressure constant.
• External pilot oil supply with internal pilot oil return, mass 12.56 kg.

Applications

The valve controls feed, lifting and closing movements on presses, injection moulding machines and test rigs that run ramps. Concealed auxiliary actuation allows the axis to be moved without the control electronics. NBR seals are fitted for mineral oil of class HL.
