Proportional Directional Valve 4WRZ10E50-7X/6EG24EK4/M - Bosch Rexroth R901479661

Controlled cylinder axes need a valve whose opening follows the signal instead of merely switching. The 4WRZ10E50-7X/6EG24EK4/M is a pilot operated size 10 proportional directional valve with 50 l/min nominal flow, up to 170 l/min maximum flow and 315 bar operating pressure.

Benefits

• 50 l/min nominal flow as the design point of the characteristic curve, with 170 l/min available at maximum.
• 315 bar maximum operating pressure with spool symbol E across three switching positions.
• Internal pilot oil supply with external return, which simplifies piping inside the manifold.
• 7-pole connector (6 + PE) to EN 175201-804 for the link to the external amplifier.
• 7.76 kg weight, subplate mounting to ISO 4401-05-05-0-05.

Application

The valve is used in positioning and force control axes, for example on test rigs, presses and plastics machinery. This version does not include a pressure reducing valve in the pilot stage.
