Proportional Directional Valve 4WRZE32E1-520-7X/6EG24N9TK31/A1V - Bosch Rexroth R978018837

Some circuits supply pilot oil from a separate source but do not need a dedicated drain line. That is the case the 4WRZE32E1-520-7X/6EG24N9TK31/A1V is built for: external pilot oil supply, internal pilot oil return, 520 l/min nominal flow in size 32 and 350 bar operating pressure.

Benefits

• External pilot oil supply with internal pilot oil return saves one line while keeping the pilot stage independent of main pressure.
• Spool symbol E1, three switching positions, four ports, ISO 4401-10-09-0-05 mounting pattern.
• 520 l/min nominal flow and up to 1600 l/min maximum at 350 bar operating pressure.
• On-board electronics, ±10 V command value, 24 VDC supply, 7-pole connector (6 + PE) to EN 175201-804.
• FKM seals, HL hydraulic fluid, concealed manual override, weight 44 kg.

Applications

The variant suits machines with a central pilot supply and an unloaded tank line, such as presses, test benches and forming equipment. Subplate mounting to ISO 4401-10-09-0-05 lets you swap it against other valves of the same series without reworking the manifold.
