Qmax cut control
The regulator regulates the
maximum delivery flow by
inputting the pilot pressure
Pm. Since this is a 2-
position control method, the
maximum delivery flow may
be switched in two steps by
turning on/off the pilot
pressure Pm.(The maximum
control flow cannot be
controlled in intermediate
level.)
