Danfoss electronic displacement control is a two-stage electrohydraulic pump stroke control which uses mechanical feedback to establish closed loop control of the swashplate angle of Danfoss Series 90 Pumps.

The first stage, the MCV110 Pressure Control Pilot (PCP) is a torque-motor actuated, double-nozzle flapper valve that produces a differential output pressure proportional to the applied electrical signal. The second stage uses the differential pressure to drive its unique spool arrangement and port oil to the pump servo cylinders. The second-stage spool configuration allows a null deadband (for machine safety) in the pump’s output while maintaining optimum dynamic response to control commands.
