NOTE:
All activities must be carried out in order to ensure proper actuator operation.
Always read all instructions before beginning maintenance.
Bettis RGS Q-Series actuators are composed of two or three basic sub-assemblies, one or
two force modules and a torque module. The force module contains the piston and rack
which provide linear motion. The torque module contains the gear which converts the
force modules’ linear motion into torque and operates the valve.
Every actuator assembled by Bettis is tested prior to shipment to our customers.
Order specific documentation may be available upon request.
