Valve actuators are mechanical devices that use a power source to operate a valve. 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.

Flowserve Limitorque® is the world's oldest supplier of intrusive, electromechanical multi-turn actuators and continues to produce the world class L120 and SMB series of electric actuators.
The Limitorque® LTQ compact, quarter-turn electric actuator delivers superior reliability and performance through its industry-proven epicyclic locking gear set design.
Flowserve Limitorque is a world class supplier of the non-intrusive, electronic multi-turn MX series of actuators.
Actuators requiring 90° of rotation to operate are necessary for quarter-turn valves such as ball, butterfly, plug and dampers, and rotary control valves.
The TEC2 Electric Actuator is the next generation of the non-intrusive TEC2000 actuator.
For 60 years Rotork has used innovation for designing reliable, flexible and robust valve actuators and control systems.
Technologically innovative while incorporating proven engineering, Rotork watertight CK range actuators are suitable for all valves in non-hazardous locations.
Small, electro-mechanical part-turn actuator environmentally sealed to IP68.
ROM actuators provide quiet and reliable operation for all kinds of small ball valves and butterfly valves, as well as dampers and ventilation louvres.
The ROM range of actuators can be enhanced with the addition of a self-contained control package to create a ROMpak actuator.
PAX units are flexible, low voltage actuators that are designed for use in remote, explosionproof locations.
