Proportional Directional Valve 4WRZ10E1-85-7X/6EG24ETK4/D3M - Bosch Rexroth R901021450

A proportional valve with internal pilot routing saves two ports on the manifold along with their lines. The 4WRZ10E1-85-7X/6EG24ETK4/D3M is built that way and meters a nominal flow of 85 l/min in size 10.

Benefits

• Internal pilot oil supply and internal return, no external pilot lines needed
• 85 l/min nominal flow within a flow range reaching 170 l/min
• Integrated pressure reducing valve keeps pilot pressure inside its permitted band
• Spool symbol E1, 3 switching positions, 4 ports, 315 bar
• 24 VDC through external electronics, 7-pole (6 + PE) connector to EN 175201-804
• 8.2 kg in the ISO 4401-05-05-0-05 interface, NBR seals

Applications

This variant appears in plastics machinery and presses whose system pressure is not switched off during the cycle. Because pilot oil comes from the working circuit, sufficient pressure has to be present while metering. The electronics are sourced separately and matched to the axis.

Manufacturer

Bosch Rexroth carries material number R901021450. Minimum pressures, curves and the matching amplifier electronics are named in data sheet RE 29115, supplemented by RE 07600-B.
