Proportional Directional Valve 4WRZE32W6-360-7X/6EG24N9ETK31/A1D3M - Bosch Rexroth R901046280

Swapping a size 32 valve costs the time it takes to break lines plus the effort of carrying the part. This version of the 4WRZE32W6-360-7X weighs 40.6 kg, works without external control lines, meters 360 l/min at 350 bar.

Benefits

• 40.6 kg on the ISO 4401-10-09-0-05 pattern for subplate mounting.
• Internal pilot oil supply with internal return leaves no control lines to break during a swap.
• 360 l/min nominal flow in size 32 at a flow limit of 1600 l/min.
• ±10 V command into on-board electronics, supply 24 VDC.
• Spool symbol W6, three switching positions, four ports, concealed auxiliary actuation.
• 350 bar operating pressure with NBR seals on HL hydraulic fluid.

Application

It makes sense wherever downtime is expensive so a valve change has to be quick, production lines with clamping hydraulics for instance. The internal pilot circuit assumes a system pressure that sustains the pilot pressure at all times. The auxiliary actuation allows the axis to be set up while the system is depressurised.
