New digital positioner for electric actuators
The new digital positioners baelz 7020 and baelz 7020A make for greatly simplified operation and adjustment, offering fully automatic adaptation to a control valve, for example. The 7020 is supplied built into our actuators baelz 373-E07. The 7020A is available for our actuators baelz 373-E45, baelz 373-E66 and baelz 375-E42.
The digital positioner receives a positioning signal from a master controller and converts the signal directly. Position feedback enables automatic control according to operating pressure and actuating thrust.
