Flowserve—Limitorque Actuation Systemsn logo


Limitorque actuators are a well-known name in the world of flow control. For more than 85 years they have been transforming actuation with their “torque-limiting” design. Today, they offer heavy-duty electric and pneumatic actuators as well as gearboxes and controls.

Flowserve Limitorque products help make valve control easier in ways as diverse as the applications in which they are used. Whether you need an electric actuator with the strength to handle 2224 kN (500 000 lb) of thrust, a fluid power actuator to deliver 300 kNm (221 270 ft-lb) or more of torque or a sophisticated control network to precisely orchestrate hundreds of valves, you will find that Limitorque products make the task easier.
