Hydraulic Motor/Pump
Series V14
EO/EP/HO/HP control description
Basically, the controls function in a similar
way. At increasing solenoid current (EP) or
increasing pilot pressure (HP) the control
moves towards the min displacement posi-
tion. At decreasing current/pilot pressure, the
control retracts towards max displacement.
In comparison with EP and HP, the EO and
HO controls have no modulating spring or
feedback arm; this means that only min and
max displacements (but no intermediate
positions) are available with these controls.
