Proportional Directional Valve 4WRKE27E1-500L-3X/6EG24EK31/A1D3M - Bosch Rexroth R900249274

On the 4WRKE27E1-500L-3X/6EG24EK31/A1D3M the piping effort stays low without the pilot stage suffering from the return level of the main circuit. Spool symbol E1 releases 500 l/min nominal flow on a linear curve, 1000 l/min is possible for short periods, and the internal position transducer corrects the spool.

Benefits

• Internal pilot supply with external return, only one extra line at the block.
• Spool symbol E1 with a linear curve, 500 l/min nominal flow, up to 1000 l/min.
• Operating pressure to 270 bar in size 27 with four ports.
• Closed loop spool position control through the internal transducer, ±10 V command.
• NBR seals, 19.46 kg, mounting pattern ISO 4401-08-08-0-05.

Application

The valve suits presses, drawing lines and test rigs with a heavily loaded return manifold. Mineral oil of class HL is intended. Control runs through a 7-pole plug to EN 175201-804 on 24 VDC.
