Limitorque has evolved over almost 90 years since its strategic introduction of a “torque-limiting” design. Today, all heavy-duty electric actuators use some device that “limits the torque” in order to safely operate automated valves and protect people and property. True to its name, Limitorque offers solutions and automation choices for customers with world-class electric and electronic products and an expanded range of fluid power actuators and control systems that provide:
The Limitorque brand, which for scores of years has been the trademark customers trust when safe, reliable and robust performance was demanded from electric actuators, is now available in heavy-duty, scotch yoke pneumatic actuators.
Flowserve Limitorque: the only actuator brand you need to know for world-class actuator solutions.
The Limitorque product range includes actuators that can be controlled from customers’ motor control centers to electronic actuators that can be remotely controlled field devices. More than 1 million Limitorque actuators have been installed around the world, and some have been in operation for more than 50 years. The ruggedness and reliability of Limitorque electric actuators are among the primary reasons that customers continue to select Limitorque products.Learn More
Built upon a modular scotch yoke torque system, Limitorque fluid power actuators are designed to deliver maximum torque with the lowest possible displacement and overall size. The use of high-strength, wear-resistant materials ensures the actuators operate efficiently and reliably in high-cycle, heavy-duty applications.Learn More
Gearboxes such as the WG, V, or SR series provide the mechanical advantage to make hand operation possible for most valves. Where automated process control is needed or torque requirements are too high for manual operation to be practical, these gearboxes can be coupled to MX, L120 or SMB actuators.Learn More
Limitorque ensures complete integration with plant control systems by offering a variety of open-architecture digital network protocols and controls. Once the standard network commissioning is complete, all connected actuators will provide robust and reliable valve system monitoring and control for years to come.Learn More
When needed, the services provided for Limitorque actuators meet customer expectations for quick comprehensive coverage.Learn More
Well-trained people are usually the best ambassadors for Limitorque products. For that purpose Limitorque offers in-depth training for key products.Learn More
