Characteristics for float position main spools
Characteristic of oil flow, spool travel and voltage
•
4.8 mm [0.19 in] spool displacement in direction A gives maximum oil flow to port A
•
4.8 mm [0.19 in] spool displacement in direction B gives maximum oil flow to port B
•
8 mm [0.32 in] spool displacement in direction B gives completely open float position A/B → T.
The spools have 4.8 mm spool travel in direction A and 8 mm travel in direction B:
For more information regarding electrical actuation of float spools please see PVE series 4 Technical
Information, 520L0553.
Pressure drop A/B → T at maximum spool travel within the proportional range (4.8 mm) [0.19 in]
Spools D and E have the same opening area for forward flow and return flow.
Spool E can give 100 l/min [26.4 US gal/min] pressure compensated oil flow due to a higher pressure
drop across spool E. This occurs during spool actuation only.
