Proportional Directional Valve 4WRZ10W8-85-7X/6EG24TK4/D3M - Bosch Rexroth R901119152

Some manifolds have a dedicated pilot supply but no spare return port. The 4WRZ10W8-85-7X/6EG24TK4/D3M is built for that case, draining externally fed pilot oil internally while metering 85 l/min nominal flow.

Benefits

• External pilot oil supply with internal return, one return port less on the manifold
• 85 l/min nominal flow, flow range up to 170 l/min
• Spool symbol W8 with 3 switching positions and 4 ports
• 315 bar maximum operating pressure in the ISO 4401-05-05-0-05 interface
• 24 VDC through external amplifier electronics, 7-pole (6 + PE) connector to EN 175201-804
• 8.22 kg, integrated pressure reducing valve, NBR seals for HL

Applications

The valve goes into manifolds whose pilot oil comes from a separate pump or an accumulator. Internal return assumes that back pressure in the tank channel stays within the limits of the data sheet. Size 10 keeps the valve on a standard hole pattern.
