When the pressure reaches the
value set with the compensator,
the flow is reduced automatically
and the set pressure is maintained.
The pressure and flow are
controlled manually.
The "HL" compensator is used for
load sensing circuits and is a true
load sensor. This is the "B" compensator
with a pin in the compensator spool.
The pin prevents pilot flow from entering
the circuit which will eliminate creeping
of the load.
The "HL" compensator will let the
pump deliver a constant flow rate to
the circuit by providing an adjustable
△
P across the customers orifice or
valve. The pump will operate at
17.2~27.5 bar (250-400 psi) above"Load pressure".
