In steelworks the tank pressure swings hard, which throws internally drained pilot stages off their timing. This valve separates its pilot circuit from the main circuit on both sides, controlling 360 l/min at 350 bar. It weighs 45 kg, driven by a ±10 V command.

BRR-R901056078

Behind a rolling stand the tank line pressure moves with every pass, taking an internally drained pilot stage along with it. The 4WRZE32W6-360-7X keeps both pilot supply plus pilot drain outside that line, holding 360 l/min at 350 bar.

Benefits

  • External pilot supply with external drain keeps the control circuit apart from pressure surges in the tank line.
  • 360 l/min nominal flow in size 32, flow up to 1600 l/min.
  • ±10 V command into on-board electronics on 24 VDC.
  • Spool symbol W6, three switching positions, four ports, concealed auxiliary actuation.
  • 350 bar operating pressure, NBR seals, HL hydraulic fluid, 45 kg.
  • ISO 4401-10-09-0-05 interface for subplate mounting, 7-pole connector (6 + PE) to EN 175201-804.

Application

Rolling stands, continuous casters or shears work with short hard load peaks on a shared return. Piloting externally on both sides keeps the response times independent of those peaks. For setup work or a loss of control voltage the concealed auxiliary actuation helps.

Manufacturer

Bosch Rexroth, material number R901056078, product family 4WRZ(E). Pilot pressure, curves plus mounting position are documented in data sheet RE 29115, RE 07600-B places the valve within the programme. Conformity UKCA under SI2016/1091.
