Proportional Directional Valve 4WRZE32W6-520-7X/6EG24N9EK31/A1V - Bosch Rexroth R978008881

A press or a test rig that meters 520 l/min needs a pilot-operated valve in size 32. The 4WRZE32W6-520-7X/6EG24N9EK31/A1V handles this rated flow at up to 350 bar operating pressure and passes up to 1600 l/min.

Benefits

• 520 l/min rated flow, flow up to 1600 l/min
• Maximum operating pressure 350 bar, ISO 4401-10-09-0-05 port pattern for subplate mounting
• Spool symbol W6 with three switching positions and four ports
• Internal pilot oil supply, external pilot oil return, version without pressure reducing valve
• Concealed auxiliary actuation, ±10 V command value through a 7-pole connector (6 + PE) to EN 175201-804
• FKM seals for HL fluid, 44 kg installed weight, UKCA conformity to SI2016/1091

Applications

Size 32 works in presses, foundry equipment and test rigs with high oil demand. Pilot oil is taken internally and drained externally to tank, so a Y port has to be provided on the subplate. The concealed auxiliary actuation allows the spool to be moved without an electrical signal.
