Limitorque.

Since 1929, more than 1 million Limitorque actuators have been installed around the world, and some have been operating for more than half-century. These world-class actuators have been used to consistently drive multi-turn and quarter-turn industrial valves and dampers. 

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. 

Limitorque offers a wide range of solutions and automation choices. World-class electric and electronic products, plus an expanded range of fluid power actuators, Scotch yoke pneumatic actuators and control systems provide proven benefits like these: 

  • Automation advantages, including cylinder-operated fluid power actuators and Limitorque’s unparalleled range of heavy-duty electric actuators 
  • Greater operating efficiencies, ranging from control room performance sequencing and continuous process optimization to configuration of emergency shutdown (ESD) situations and SIL-rated safety for electric- and fluid-powered devices 

A full suite of digital network protocols, delivering visibility of databases and proactive diagnostics — compatible with electric- and fluid-powered actuators
