  • Control options

    Hand wheel

    For manual operation, the handwheel is offered in cast iron material which allows for very comfortable and easy operation.

    Pneumatic drive

    The following actuators are available: double-acting actuator (air opening/closing), spring to close (to ensure closing in case of air failure), spring to open (to ensure opening in case of air failure).

    Electric drive

    Series 97 are designed as quarter-turn. These actuators can be installed on ABO butterfly valves in 24V, 230V and 400V versions from world leading suppliers such as Auma, Regada and Valpes.
