Digitalization the Baelz way

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 E07 actuators. The 7020A is available for our E42, E45 and E66 actuators.

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.

Controller integrated in an actuator

baelz 7164

This decentralized intelligent controller is integrated in the actuator unit, minimizing on-site installation and wiring work and replacing the signal wiring between controller and actuator.
