Pressure Controls

Pressure Compensator: Ensures maximum pump flow until unit reaches preset control pressure setting then regulates output flow to match the requirements of the system while maintaining preset output pressure.
Dual Pressure Compensator: Provides two independently adjustable pressure compensated deliveries as selected by an integral solenoid.
Low Pressure Compensator: Works the same as the Pressure Compensator Control except it provides a lower minimum pressure. Can be adjusted from 250 psi working pressure up to a maximum of 1500 psi.
Dual Pressure Compensator with Load Sensing: Maintains a constant flow rate at up to either of two independently adjustable pressures as selected by an integral solenoid.
Load Sensing: A constant flow output is maintained for a given flow control valve setting regardless of changes in drive speed and/or working pressure.
Soft Start Pressure Compensator: Pump starts "softly" by shifting quickly at low pressure to a reduced flow setting, thereby reducing start-up torque requirements.
High-Low Pressure Compensator: Ensures maximum pump flow until unit reaches preset control pressure setting, then de-strokes the pump to provide an adjustable minimum preset flow rate regardless of system pressure.
Horsepower Limiting: Automatically reduces delivery as unit pressure rises, to limit horsepower consumption.
Electronic Proportional Pressure Compensator: Provides an infinite number of independent remotely adjustable pressure settings in response to an electrical command.
Remote Operator: Remote control module can be used with most pressure controls. The control itself may be mounted remote from the pump and convenient to the operator for ease of adjustment.
Horsepower Limiting with Load Sensing: Load sensing control matches flow and pressure to load demand until horsepower limiting setting is reached. Control then automatically reduces delivery as unit pressure rises.

Displacement Controls

Handwheel: Provides simple manual handwheel adjustment of delivery.
Fixed Displacement: Pump stroke (displacement) is locked in place and cannot be adjusted (changed).
Lever Operated with Neutral Bypass: Varies displacement proportional to rotation of a pintle which is equipped with a "neutral" bypass to prevent creep when centered.
Lever Operated: Varies displacement proportional to the rotating of a pintle.
Electronic Servo Valve: An electrohydraulic servo valve positions the swashplate mechanisms with a closed loop position control (with LVDT feedback) providing high accuracy remote variable delivery control.
Proportional Electronic Control: A proportional DC coil controls a pilot control that provides infinite4ly variable displacement control.
