Proportional Directional Valve 4WRZE32W6-520-7X/6EG24N9EK31/A1D3V - Bosch Rexroth R900725320

High back pressure in the return line distorts pilot control. The 4WRZE32W6-520-7X/6EG24N9EK31/A1D3V therefore takes pilot oil internally from the main circuit but drains it externally and without pressure, controlling 520 l/min nominal flow from the ±10 V command.

Benefits

• Internal pilot oil supply with external pilot oil return, pilot stage kept clear of return line back pressure
• 520 l/min nominal flow, max. flow 1600 l/min
• Spool symbol W6, 3 switching positions, 4 ports
• ±10 V command, 24 V DC via 7-pole connector (6 + PE) to EN 175201-804
• Max. operating pressure 350 bar, FKM seals
• Weight 43.9 kg, interface ISO 4401-10-09-0-05

Applications

Recommended in systems with return filters, coolers or long tank lines where back pressure builds up at port T. Typical machines are large presses, forging hammers and test benches with high return flow.
