Limitorque Electric Actuator Sizing

The qx design builds on more than 20 years of proven mx technology to provide all the user preferred features in a quarter turn smart actuator package.

Limitorque electric actuator sizing.

These types of limitorque electric actuators are available for operations such as open close modulating network and rotary service. 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. The qx is the flowserve limitorque product for the quarter turn valve market up to 1500 ft lb. By properly sizing an actuator to a valve for a specific application performance is guaranteed and economies are gained.

Smb actuator sizing and applications training course length. Expressed as a fraction distance in inches number of threads lead is the number of revolutions or turns around the stem for an increment of travel in inches. The basics of electric actuators. Valve torque before the actuator can be sized for any given valve application the amount of torque required by the valve must be determined.

Lynchburg this course details smb actuator selection and provides a step by step sizing process for multi turn and quarter turn applications. The relationship between valves and actuators. Store actuators in a clean dry protected warehouse away from excessive vibration and rapid temperature changes. You ll get specific recommendations based on the flowserve team s decades of industry leadership and practical experience.

The flowserve limitorque qx non intrusive electric actuator is designed for a wide range of environmental applications in power oil gas and water industries. For longer term storage contact limitorque for procedures and recommendations. Actuator sizing pitch is the number of threads linearly along the stem. Storage less than 1 year actuators are not weatherproof until properly installed on the valve or prepared for storage.

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. Electric actuator ranges also include the awt for simplified control duties rom rompak and q direct drive actuators for small quarter turn valves. Rotork actuators are compatible with a wide range of communication and process control systems. 2 to 2 5 days 16 20 hours total location.

Flowserve limitorque mx actuators flowserve limitorque mx actuators have been engineered to accommodate today s wide variety of valve designs and to meet international standards for valve and actuator interfaces. Beyond that range any of the multi turn products can be assembled with wg or hbc 90 worm gearbox operators to.
