Proportional Directional Valve 4WRKE32W6-400L-3X/6EG24K31/F1D3M - Bosch Rexroth R901117295

On a dredger or inside a lock chamber the power unit, the controller and the valve are rarely close together. The 4WRKE32W6-400L-3X/6EG24K31/F1D3M handles both distances, since it draws pilot oil externally and is commanded by 4 to 20 mA.

Benefits

• External pilot oil supply and return - a dedicated pilot circuit independent of the main one.
• Command value 4 to 20 mA, so long cable routes are bridged without signal loss.
• 400 l/min nominal flow in size 32, up to 1550 l/min at 350 bar.
• Symbol W6 with internal spool position feedback and three switching positions.
• 37.2 kg, ISO 4401-10-09-0-05 interface, NBR seals for HL fluid.

Application

Valves like this work on water engineering plants, dredgers and harbour cranes whose drives are spread out. The dedicated pilot circuit allows the pilot stage to stay pressurised while the main drive stands still. Wiring uses a 7-pole connector (6 + PE) to EN 175201-804.
