Proportional Directional Valve 4WRKE25E1-350L-3X/6EG24EK31/A1D3V - Bosch Rexroth R901419190

Large axes often run off the same controller as the small ones and therefore receive ±10 V as their command value. This size 25 valve accepts exactly that signal and turns it into up to 350 l/min nominal flow, with spool symbol E1 and a linear characteristic.

Benefits

• 350 l/min nominal flow controlled straight from an ordinary ±10 V analogue output.
• Spool symbol E1 with linear characteristic, peak flow up to 870 l/min.
• Internal pilot oil supply with external return through Y saves one line of pipework.
• Internal spool position feedback holds the spool even against large flow forces.
• FKM seals, interface ISO 4401-08-08-0-05, weight 17.92 kg.

Applications

The combination is used in plants where axes of different sizes hang off one controller, for example forming lines and test fields. A uniform signal type simplifies spare part stocking and commissioning. System pressure in port P is enough to feed the pilot stage.
