Proportional Directional Valve 4WRZE10W8-50-7X/6EG24ETK31/F1D3M - Bosch Rexroth R901046936

The 4WRZE10W8-50-7X/6EG24ETK31/F1D3M addresses plants whose controller issues current signals and which should manage without pilot lines. Supply and return run internally, and the 4...20 mA command value drives the spool of symbol W8. 50 l/min nominal flow and 315 bar operating pressure define the working range of size 10.

Benefits

• Command value 4...20 mA, directly connectable to controllers with a current output.
• Internal pilot supply and internal return, no X and Y lines required.
• 50 l/min nominal flow, maximum flow up to 170 l/min.
• Operating pressure up to 315 bar, mounting pattern ISO 4401-05-05-0-05, weight 9.1 kg.
• On-board electronics on 24 VDC, 7-pole connector (6 + PE) to EN 175201-804.
• Spool symbol W8, pressure reducing valve in the pilot stage, UKCA conformity.

Application

This version is found in machine tools and handling equipment where short piping and interference-tolerant signalling are wanted. The internal pilot tap requires pressure in port P throughout the movement. The return line should show low back pressure.
