From Emerson Process Management, Valve Automation
 

 
Bettis manufacturers the broadest variety of valve actuator types in the world. Our offering includes pneumatic, hydraulic, electric and gas/hydraulic powered quarter-turn actuators. We also manufacture linear actuators for multi-turn valves. Our products operate in numerous configurations including double-acting and spring-return scotch-yoke, rack and pinion, helical-spline and rotary vane.

Products & Services
Electric valve actuators mount on valves which, in response to a signal, automatically move to a desired position using an outside power source. Single-phase or three-phase AC or DC motors drive a combination of gears to generate the desired torque level. Search by Specification | Learn more about Electric Valve Actuators
Valve actuators mount on valves and, in response to a signal, move a valve to a desired position using an outside power source. Search by Specification | Learn more about Valve Actuators
Valve positioners compare a control signal to a valve actuator’s position and move the actuator accordingly. They are used with both linear valves and rotary valves. Search by Specification | Learn more about Valve Positioners
Electrohydraulic valve actuators and hydraulic valve actuators convert fluid pressure supply pressure into motion. Search by Specification | Learn more about Electrohydraulic Valve Actuators and Hydraulic Valve Actuators
Valve position indicators are devices that show the position of the closure element. Search by Specification | Learn more about Valve Position Indicators
