Overview of control units
OV - Without control
▼ Circuit diagram
At axial piston units without OV control, the stroking
piston is based on DR control. The stroking piston is
relieved to the tank. The V
g max
limitation can be adjusted
from 50 to 100%. The axial piston unit without control acts
like a fixed pump in operation.
