Proportional Directional Valve 4WRKE32W6-400L-3X/6EG24EK31/F1D3M - Bosch Rexroth R901122589

A crowded tank channel pushes against the pilot stage and shifts the null point. The 4WRKE32W6-400L-3X/6EG24EK31/F1D3M releases its pilot oil externally, takes it internally and carries 400 l/min nominal flow.

Benefits

• External pilot oil return - the null point stays stable even with back pressure in channel T.
• Internal pilot supply saves the X line at the manifold.
• 400 l/min nominal flow, up to 1550 l/min at 350 bar operating pressure.
• Command value 4 to 20 mA on 24 VDC, symbol W6 with linear characteristic.
• 37.3 kg, NBR seals, HL fluid, ISO 4401-10-09-0-05 interface.

Application

The version fits plants with many consumers on one return, such as central hydraulic stations in rolling mills and paper machines. A separate return protects the pilot stage from pressure surges in the collecting channel. The command arrives as a current and stays accurate over long routes.
