Limitorque®

Actuators & Instrumentation

Since 1929, Limitorque actuators have been making flow control easier among a broad range of applications. These actuators are world-class devices used to consistently drive multi-turn and quarter-turn industrial valves and dampers, providing years of dependable service. More than 1 million Limitorque actuators have been installed around the world — and some have been in operation for more than a half-century.

Limitorque changed the industry with its strategic introduction of a “torque-limiting” design. Today, all heavy-duty electric actuators use some device that “limits the torque” to safely operate automated valves and protect people and property.
