Actuation Technologies

Engineering a valve automation system that will provide reliable execution under extreme conditions in the most remote locations is no simple task. Today, automating valves requires a lengthy and costly engineering and procurement process to determine, acquire, test and finally commission the best valve control assemblies for the operation.

Emerson recognized the need for a better process. This is why the Bettis Valve Operating System (VOS) was created.

A broad range of hydraulic actuators with a choice of rack and pinion, scotch yoke, helical slot and linear designs suitable for heavy-duty service in the harshest environmental and operating conditions. Rack and pinion actuators provide the most economical on-off and modulating control for small to medium quarter-turn valves. The scotch yoke design creates high break-out torques making them suitable for quarter-turn valves up to the largest sizes. Helical slot is used when a reduced foot print impact is requested (it is available with a four-different output curves equivalent to R&P or SY), including models for very high-pressure applications.

Market Leading Portfolio of Electric Actuators from Bettis™ is a leading brand in the broad offering of Emerson. The actuators and controls are used in almost every energy-related industry, including oil and gas transmission, petrochemical and petroleum refining. Other significant markets include chemical; power industry including nuclear; pulp and paper; food and beverage; pharmaceutical; HVAC and water systems.
