bias spring pressure. Since the pressure drop varies with pump flow volume led to tank, the A and B work
port flow will vary.
In closed center systems, the pressure drop across the main spool equals the standby setting of the
pump, measured at the P-port of the valve. The A and B work port flow will remain unchanged as long as
the standby is unchanged.
PVBS main spools with linear characteristic deliver a higher flow gain directly proportional to the linear
spool travel beyond the dead band.
