Proportional Directional Valve 4WRZE10E1-85-7X/6EG24N9TK31/A1V - Bosch Rexroth R900948330

In crushing plant the disturbance arrives from outside, as a shock in the crushing gap. The 4WRZE10E1-85-7X/6EG24N9TK31/A1V holds the adjusting axis against it at 85 l/min rated flow and 315 bar maximum, drawing its pilot oil from a circuit of its own.

Benefits

• External pilot oil supply with internal pilot oil return, pilot stage independent of the working circuit.
• 85 l/min rated flow for fast readjustment, flow up to 170 l/min.
• Spool symbol E1, three switching positions, operating limit 315 bar.
• Command value 10 V bipolar into the on-board electronics, 24 VDC supply.
• Concealed manual override, 7.98 kg, size 10, FKM seals for HL fluid.

Application

Cone and jaw crushers, screening plant and adjusting axes in mineral processing use this control. Because pilot oil is supplied externally, the pilot stage stays fed while working conditions fluctuate. Smaller adjusting axes run at 25 or 50 l/min.
