Proportional Directional Valve 4WRTE25E1-350P-4X/6EG24ETK31/F1M - Bosch Rexroth R901259462

Retrofitting an existing axis is mostly a question of how little extra has to be routed. The 4WRTE25E1-350P-4X/6EG24ETK31/F1M needs neither pilot lines nor a voltage interface, because the pilot stage runs internally, the command arrives as 4...20 mA and 350 l/min are available at up to 350 bar.

Benefits

• Internal pilot oil supply and internal return make additional pilot lines unnecessary.
• A 4...20 mA command survives long cable runs without level loss.
• 350 l/min nominal flow with spool symbol E1 and a fine control range.
• Internal spool position feedback secures reproducible curves up to 350 bar.
• Mounting pattern ISO 4401-08-08-0-05, 7-pole connector (6 + PE) to EN 175201-804, 18 kg.

Applications

Retrofits on presses, hoists and feed axes are the main field, because the valve goes in without reworking the control block. Pilot pressure comes from working pressure, which therefore has to stay present. NBR seals cover mineral oil of class HL.
