Proportional Directional Valve 4WRZE32W6-360-7X/6EG24N9K31/A1D3M - Bosch Rexroth 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.
