Important: Starting in October, 2019, the base actuators are gradually being replaced with an updated design. Documents of the new design are marked with Release 2 - 2019. The Control Modules of the Bettis Q-Series remain unchanged.
The Bettis Q-series is an integrated rack & pinion actuator concept with a base actuator and various control modules for control and feedback signals. Bettis Q-Series are designed to operate quarter turn valves or any other quarter turn application. Bettis Q-Series consists of 9 actuator sizes (spring return or double acting) and 5 control modules for conventional wiring or with bus communication protocols like AS-Interface or Foundation Fieldbus.
