Description
Combining external pilot oil supply with internal pilot oil return saves a return line without making the pilot stage depend on main pressure. That is how this version of the 4WRLE16V1-250P-4X is arranged, rated for 250 l/min.
Benefits
- External pilot oil supply and internal pilot oil return means one line less at the subplate
- 250 l/min nominal flow, peak flow up to 800 l/min
- Plus/minus 10 V command value matches widely used analog output cards
- Spool symbol V1 with fine control range for soft start-up
- Internal spool position feedback, 350 bar operating pressure
- CE conformity, weight 11.64 kg, connection diagram ISO 4401-07-07-0-05
Applications
Suited to machines with a dedicated pilot oil source whose return is routed through the main circuit anyway. Typical applications are press axes and approach units under varying load. Hydraulic fluid HL and NBR seals cover standard mineral oil operation.
