Proportional Directional Valve 4WRTE16W8-150L-4X/6EG24K31/F1M - Bosch Rexroth R901420829

Where a controller issues its command values as a current signal, the 4WRTE16W8-150L-4X/6EG24K31/F1M fits without a converter in between: the input works with 4...20 mA and drives the spool of symbol W8 through on-board electronics with position feedback. At 150 l/min nominal flow and 350 bar operating pressure it covers the size 16 power range, with maximum flow reaching 460 l/min.

Benefits

• Command value 4...20 mA, so the control loop connects straight to controllers with a current output.
• On-board electronics with internal spool position feedback, supplied from 24 VDC.
• 150 l/min nominal flow, reserve up to 460 l/min maximum flow.
• Operating pressure up to 350 bar with mounting pattern ISO 4401-07-07-0-05, subplate mounting in size 16.
• External pilot oil supply and external pilot oil return keep the pilot stage separate from the main circuit.
• Spool symbol W8, 3 switching positions on 4 ports, weight 11.04 kg.

Application

The valve serves feed and positioning axes of medium size, for instance on presses, test rigs and handling systems. External pilot supply calls for a dedicated pilot pressure source, in return the pilot pressure stays independent of load pressure. Hydraulic fluid HL is specified for operation, the seals are made of NBR.
