Proportional Directional Valve 4WRZE32E1-520-7X/6EG24TK31/A1D3M - Bosch Rexroth R901060582

Mounting pattern ISO 4401-10-09-0-05, 520 l/min nominal flow and 42.5 kg mass describe this pilot-operated proportional directional valve in size 32. The built-in pressure reducing valve holds the pilot pressure steady even when the externally supplied pilot oil sits above it.

Benefits

• Nominal flow 520 l/min, maximum flow 1600 l/min at 350 bar operating pressure.
• Integrated pressure reducing valve in the pilot circuit, so the external pilot supply does not have to be throttled down beforehand.
• Internal pilot oil return, which leaves the pilot feed line as the single external pipe to route.
• ±10 V command value on the on-board electronics, 24 VDC supply through a 7-pole (6 + PE) connector to EN 175201-804.
• Spool symbol E1 with 3 switching positions and 4 ports, subplate mounting to ISO 4401-10-09-0-05.
• NBR seals for HL hydraulic fluid, weight 42.5 kg.

Applications

Size 32 valves sit on the main cylinders of forging presses, on roll adjustment drives and on test machines with large piston areas. Because the pilot oil comes from outside, the pilot circuit can be filtered and cooled on its own, while the pressure reducing valve inside the body secures the working point of the pilot stage. The pilot oil return runs internally into the tank passage of the subplate.
