o Pressure Compensator The pressure compensator control will limit pump
outlet pressure to a predetermined level and adjust pump outlet flow to the level needed to maintain the set pressure.
o Remote Pressure Compensator
Same as the pressure compensator , except that the adjustment is done with a remotely located relief valve instead of at the pump control.
o Load Sense Control
Load sense control will adjust output flow to maintain a constant pressure drop across an orifice.
Torque Limiter Control
Will adjust flow to limit the input torque demand of the pump.
