Proportional Directional Valve 4WRKE35W6-1000P-3X/6EG24ETK31/A1D3M - Bosch Rexroth R901205315

The fewer extra lines a large valve needs, the simpler the control manifold becomes. The 4WRKE35W6-1000P-3X/6EG24ETK31/A1D3M feeds its pilot stage internally and returns the pilot oil internally as well, at 1000 l/min nominal flow and 350 bar operating pressure.

Benefits

• Internal pilot oil supply and internal pilot oil return - no external pilot or return line has to be routed.
• Command value analog ±10 V through a 7-pole connector (6 + PE) to EN 175201-804, supply 24 V DC.
• 1000 l/min nominal flow in size 35, up to 3000 l/min by design.
• 350 bar operating pressure across four ports, HL hydraulic fluid, NBR seals.
• Symbol W6 with fine control range, three switching positions and internal spool position feedback for repeatable positions.

Application

The valve is used in compact control manifolds of large hydraulic systems where the system pressure is permanently high enough to feed the pilot stage. The ISO 4401-10-09-0-05 interface is identical to the externally piloted versions. Weight is 69.15 kg.

Manufacturer

Bosch Rexroth, material number R901205315, product family 4WRKE. Control is handled by integrated electronics directly on the valve.
