Not every large axis runs at 350 bar. For systems rated at 270 bar, this pilot-operated proportional directional valve in size 27 turns a 4-20 mA current command value into 500 l/min of nominal flow while allowing peaks to 1000 l/min.
Benefits
- Nominal flow of 500 l/min at operating pressure to 270 bar, peaks reaching 1000 l/min
- Spool symbol W8 with linear characteristic curve plus internal spool position feedback
- A 4-20 mA current command value ignores electrical interference along with cable length
- FKM seals cope with elevated oil temperature as well as more demanding media
- Connection diagram ISO 4401-08-07-0-05 at a valve mass of only 13 kg
