Flow rate regulation module Danfoss

"

The module EHF must be inserted between thee electric joystick and the PVE proportional coil.
There are two built-in potentiometers per function. Independently of one another, the latter limit the signal voltage and as such the flow rate coming from orifices A and B. 
The joystick retains its full range of adjustment as the EHF integrates a Deadband compensation and reduces the voltage instead of the mechanical reduction of the adjustment range of the joystick signal
