Limitorque Electric Valve Actuators

For more than 25 years the limitorque l120 series multi turn electric actuators have been at work in a wide variety of processes.

Limitorque electric valve actuators.

The qx is the flowserve limitorque product for the quarter turn valve market up to 1500 ft lb. Beyond that range any of the multi turn products can be assembled with wg or hbc 90 worm gearbox operators to. 81 349 nm and thrust requirements to 500 000 lb 2 224 kn. These types of limitorque electric actuators are available for operations such as open close modulating network and rotary service.

The advantages of limitorque actuators and control systems include. Whether controlling valves in commercial power feedwater or. Flowserve limitorque developed the torque limiting design decades ago and today all heavy duty electric actuators use the process to safely run automated valves. The limitorque l120 of series of electric actuators are available in nine sizes covering torque requirements to 60 000 ft lbs.

When combined with the hbc and pt worm gear operators for quarter turn valve control and multi turn dampers or with the b320 or mt bevel gear operators for gate globe and slide sluice gates the. Limitorque has evolved over almost 90 years since its strategic introduction of a torque limiting design. To help you make informed decisions about electronic actuators flowserve limitorque has compiled four quick reading white papers inspired by real world user needs and challenges. 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.
