Proportional Directional Valve 4WRZE32W6-520-7X/6EG24N9EK31/A1M - Bosch Rexroth R900976787

In continuous operation small deviations of the pilot stage add up to visible faults on the product. The 4WRZE32W6-520-7X/6EG24N9EK31/A1M therefore routes pilot oil to tank through a dedicated drain and meters 520 l/min at 350 bar from a ±10 V command.

Benefits

• Internal pilot oil supply with external drain keeps the pilot circuit clear of back pressure from the shared return.
• 520 l/min at 350 bar in size 32, the body carries up to 1600 l/min.
• W6 spool with three switching positions and four ports, ISO 4401-10-09-0-05 interface.
• ±10 V command, 24 V DC supply, 7-pole connector (6 + PE) to EN 175201-804.
• 43.6 kg, NBR seals, HL hydraulic fluid, UKCA conformity.

Applications

Typical places of use are calenders, winders and nip axes in paper and film production. A separate pilot drain keeps the pilot stage clean even with warm return oil. At 350 bar enough reserve remains for nip forces on large rolls.
