Proportional Directional Valve 4WRZE32W6-520-7X/6EG24N9TK31/A1M - Bosch Rexroth R901020004

A zero point that shifts along with system pressure ruins every calibration. The 4WRZE32W6-520-7X/6EG24N9TK31/A1M therefore separates pilot oil supply from the main circuit and meters 520 l/min at 350 bar from a ±10 V command.

Benefits

• External pilot oil supply with internal return keeps pilot pressure constant without a second line to tank.
• 520 l/min nominal flow at 350 bar, body limit 1600 l/min.
• ±10 V command with electronics inside the valve, 24 V DC supply, 7-pole connector (6 + PE).
• W6 spool on ISO 4401-10-09-0-05 with four ports and three switching positions.
• 43.06 kg, NBR seals, HL hydraulic fluid, UKCA conformity.

Applications

The valve serves hoists, stage and studio equipment as well as assembly plants with frequently changing setups. Returning pilot oil internally saves one line compared with the fully external version. A concealed auxiliary actuation stays reachable for service work.
