Valve actuators are mechanical devices that use a power source to operate a valve. This power source can be electric, pneumatic (compressed air), or hydraulic (the flow of oil). There are two main types of actuators, one for each of the two main types of valves that require them. They are rotary and linear. At Total Valve Systems, we offer a full selection of industry leading actuators in each of the types of power sources. Total Valves engineering team can work with you to determine which style and options will best serve the needs for your application.
