Proportional Directional Valve 4WRKE25W6-350L-3X/6EG24K31/A1D3M - Bosch Rexroth R900973362

Between fine positioning and a fast rapid stroke there is often nothing but the choice of spool symbol. The 4WRKE25W6-350L-3X/6EG24K31/A1D3M uses symbol W6 at 350 l/min nominal flow and draws its pilot oil from an external circuit, operating pressure up to 350 bar.

Key benefits

• 350 l/min nominal flow with spool symbol W6, maximum flow 870 l/min.
• External pilot oil supply with external return, independent of pressure in the working circuit.
• Plus minus 10 V command, 24 VDC supply, electronics carried on the valve.
• 3 switching positions and 4 ports, connection pattern ISO 4401-08-08-0-05, size 25.
• Internal spool position feedback, linear characteristic curve, NBR seals for HL hydraulic fluid.
• 17.93 kg weight, wired through a 7-pole connector (6 + PE) to EN 175201-804.

Applications

Suited to lifting axes and feed drives that alternate between rapid travel and creep. Nominal flow of 350 l/min gives the fast move headroom without losing resolution in the small signal range. A dedicated pilot circuit keeps pilot control stable even when working pressure swings hard.
