Proportional Directional Valve 4WRKE25E220L-3X/6EG24TK31/F1D3M - Bosch Rexroth R901052410

A long signal run between cabinet and press is where a voltage command loses precision. The 4WRKE25E220L-3X/6EG24TK31/F1D3M accepts 4...20 mA instead and turns it into spool travel inside its on-board electronics, 220 l/min nominal flow at 350 bar operating pressure.

Key benefits

• A 4...20 mA command stays unambiguous over long cable runs, the electronics run on 24 VDC.
• 220 l/min nominal flow in size 25, maximum flow through the valve reaches 870 l/min.
• Spool symbol E with 3 switching positions and 4 ports to connection pattern ISO 4401-08-08-0-05.
• External pilot oil supply with internal return keeps pilot pressure independent of working pressure.
• Internal spool position feedback and a linear characteristic curve, NBR seals suit HL hydraulic fluid.
• 17.92 kg weight, wired through a 7-pole connector (6 + PE) to EN 175201-804.

Applications

The valve meters advance and retract on presses, injection moulding machines and test rigs of medium flow demand. At 220 l/min nominal flow the resolution in part load stays fine enough for smooth motion. Because pilot oil arrives from a separate circuit, pilot control keeps working cleanly when working pressure drops for a moment.
