Proportional Directional Valve 4WRKE32E400L-3X/6EG24EK31/F1D3M - Bosch Rexroth R901135221

Large presses and forging lines need plenty of flow on a closed-loop axis plus a command signal the machine control can carry over a longer cable run. The 4WRKE32E400L-3X/6EG24EK31/F1D3M meters 400 l/min rated flow in size 32 and follows a current command of 4 to 20 mA.

Benefits

• 400 l/min rated flow at a maximum flow of 1550 l/min in size 32.
• Command value 4 to 20 mA into the on-board electronics, no separate amplifier card.
• Spool symbol E with 3 switching positions across 4 ports, linear characteristic with internal spool position feedback.
• Maximum operating pressure 350 bar on the ISO 4401-10-09-0-05 subplate pattern.
• NBR seals for HL hydraulic fluid, installed mass 36.94 kg.

Applications

The valve drives main cylinders on presses, forging hammers and test rigs whose demand sits around 400 l/min. Pilot oil is supplied internally and drained externally, so a Y line has to be provided in the subplate. The setpoint arrives as a 4 to 20 mA current signal from the machine control.
