Proportional Directional Valve 4WRZE32E520-7X/6EG24N9ETK31/A1D3M - Bosch Rexroth R901057363

A valve block behind panelling or high up on the frame is rarely serviced, simply because access is poor. The 4WRZE32E520-7X cuts the number of connection points by feeding pilot oil internally as well as draining it internally, at 520 l/min nominal flow under 350 bar.

Benefits

• Fully internal pilot circuit means no external control line, fewer sealing points on an awkward manifold.
• Spool symbol E with three switching positions across four ports.
• 520 l/min nominal flow, size 32, flow limit 1600 l/min.
• ±10 V command, 24 VDC supply, amplifier already built into the valve.
• 350 bar operating pressure, NBR seals, HL hydraulic fluid, 43.8 kg.
• Subplate mounting to ISO 4401-10-09-0-05, 7-pole connector (6 + PE) to EN 175201-804.

Technical data

Application

It suits paper or board machines, crane installations plus manifolds installed high or behind covers. The prerequisite is a system pressure that carries the pilot pressure permanently, otherwise the externally supplied version is the right choice. Concealed auxiliary actuation lets the axis be moved without control voltage.
