Proportional Directional Valve 4WRZE32E520-7X/6EG24N9ETK31/F1D3M - Bosch Rexroth R901069040

Every additional control line on the manifold is one more fitting that has to stay tight. The 4WRZE32E520-7X routes pilot oil internally in both directions while delivering 520 l/min nominal flow at 350 bar.

Benefits

• Internal pilot oil supply with internal return means no external control lines at all.
• 520 l/min nominal flow in size 32 at flow up to 1600 l/min.
• 4 to 20 mA current command, supply 24 VDC, on-board electronics at the valve.
• Spool symbol E with three switching positions across four ports.
• 350 bar operating pressure with NBR seals on HL hydraulic fluid at 43.64 kg.
• ISO 4401-10-09-0-05 subplate mounting, 7-pole connector (6 + PE) to EN 175201-804.

Application

The layout suits machines whose system pressure never falls below the required pilot pressure in service, clamping hydraulics or continuously running hoists for example. With no external control lines needed, the valve replaces a unit on an existing manifold without rework. Concealed auxiliary actuation is present on this version too.
