Proportional Directional Valve 4WRZE32W6-360-7X/6EG24N9EK31/F1D3M - Bosch Rexroth R901104219

In foundries the converters, furnaces plus valve controls all sit close together, where coupled interference distorts every voltage command. The 4WRZE32W6-360-7X is driven over 4 to 20 mA instead, controlling 360 l/min nominal flow at 350 bar.

Benefits

• 4 to 20 mA current command barely moves under coupled interference, supply 24 VDC.
• Internal pilot oil supply with external drain saves one feed line at the manifold.
• 360 l/min nominal flow, size 32, flow up to 1600 l/min.
• Spool symbol W6 with three switching positions across four ports.
• 350 bar operating pressure, NBR seals, HL hydraulic fluid, 43.6 kg.
• ISO 4401-10-09-0-05 interface, 7-pole connector (6 + PE) to EN 175201-804.

Application

Die casting machines or melting plants are the typical setting, since strong electrical fields meet high cycle rates there. The external pilot drain keeps the control circuit clear of back pressure in the return line. Concealed auxiliary actuation allows the spool to be moved by hand during a fault.
