When old manifolds are retrofitted the free drain line is often missing while a dedicated pilot pressure source is already in place. This version is built for exactly that case, with 220 l/min nominal flow at 350 bar in size 25.
Benefits
- External pilot oil supply with internal return, matching manifolds that have an X line but no Y line.
- 220 l/min nominal flow for mid-size cylinders, flow up to 870 l/min possible.
- 350 bar operating pressure, spool symbol W8, 3 switching positions.
- ±10 V command value with internal spool position feedback through the on-board electronics.
- 18 kg installed weight, NBR seals, connection diagram ISO 4401-08-08-0-05.
