Proportional Directional Valve 4WRZ10W8-50-7X/6EG24ETK4/D3M - Bosch Rexroth R901347522

A proportional directional valve does not open abruptly, it follows the signal sent by the controller. On the 4WRZ10W8-50-7X/6EG24ETK4/D3M this happens at a nominal flow of 50 l/min with spool symbol W8, at a maximum operating pressure of 315 bar.

Benefits

• 50 l/min nominal flow within a flow range reaching 170 l/min
• Integrated pressure reducing valve limits pilot pressure inside the valve itself
• Internal pilot oil supply and internal return, without extra lines on the manifold
• Spool symbol W8 with 3 switching positions and 4 ports
• 24 VDC through external amplifier electronics, wired via a 7-pole (6 + PE) connector to EN 175201-804
• 8.28 kg, ISO 4401-05-05-0-05 interface, NBR seals

Applications

Valves of this kind are wanted wherever a motion has to ramp up and slow down smoothly, on feed slides or lifting axes for example. The nominal flow of 50 l/min sets the speed that can be reached. The amplifier electronics sit outside the valve and are ordered separately.

Manufacturer

Bosch Rexroth lists the valve under material number R901347522. Curves, step responses and the matching amplifiers are described in data sheet RE 29115, supplemented by RE 07600-B.
