Proportional Directional Valve 4WRZE10E50-7X/6EG24ETK31/A1D3M - Bosch Rexroth R900954567

A screen changer on an extruder should travel evenly rather than in jerks. The 4WRZE10E50-7X/6EG24ETK31/A1D3M meters 50 l/min nominal flow through spool symbol E, holds up to 315 bar operating pressure and routes pilot oil supply as well as return inside the valve.

Benefits

• Nominal flow 50 l/min, maximum flow 170 l/min in size 10.
• Spool symbol E, three switching positions, four ports to ISO 4401-05-05-0-05.
• Internal pilot oil supply and internal return, pressure reducing valve in the pilot circuit.
• Operating pressure up to 315 bar, HL hydraulic fluid, NBR seals.
• Analog ±10 V command value, 24 VDC supply voltage, weight 8.49 kg.

Applications

Extruders, screen changers, pelletising lines and screw adjustment drives call for even, slow motion. The on-board electronics handle command conditioning and output stage, which removes a controller card from the cabinet. On a size 10 manifold the port pattern stays as it is.
