“Nominal Flow” for proportional spools is rated at ?p = 10 bar (145 psi) total, 5 bar per land
Example 4WRA “Nominal Flow” is 7 to 60 LPM rated @ ?p =10 bar (145 psi )
Only 145 psi pressure drop across valve!
– This is a not typical for applications
– Avoid to common mistake:
Supersizing spool = poor resolution
