Proportional Directional Valve 4WRKE32W8-400L-3X/6EG24EK31/A1D3M - Bosch Rexroth R901107424

If the tank port stays pressurised, pilot oil has to leave separately or the null point drifts. This version of the 4WRKE32W8-400L takes pilot oil internally and discharges it externally, controlled by a plus/minus 10 V voltage command.

Benefits

• Internal supply, external pilot return, stable null point despite pressure in the tank port.
• Command value plus/minus 10 V into on-board electronics, 24 V DC supply.
• 400 l/min nominal flow, up to 1550 l/min in size 32.
• Spool symbol W8, linear characteristic curve, with internal piston position feedback.
• 350 bar operating pressure, NBR seals, hydraulic fluid HL.
• 37.1 kg weight, connection diagram ISO 4401-10-09-0-05.

Applications

The valve serves large forming and lifting axes with a loaded return line, for example downstream of coolers and filters. The Y line runs to tank without a restrictor. Three switching positions across four ports form the standard circuit for a double-acting cylinder.
