Smart valve actuator Flowserve Corporation has announced the availability of the Limitorque QXM smart valve actuator, designed for rising stem valve applications, including choke valves and small control valves in the upstream oil and gas, water, fossil fuel and renewable power markets.

to 24 rpm. “The introduction of the Flowserve Limitorque QXM underscores our commitment to creating engineered solutions that help lower the total cost of ownership and increase plant uptime,” said Bill Lyon, director, research and development, Flowserve Flow Control Division. “The QXM is designed to offer reliability and long life in applications that require an uninterrupted power supply.” The QXM is the latest addition to the Flowserve next generation of smart valve actuators, which includes the Limitorque MXa and the Limitorque QX. The actuators serve a wide variety of applications and are supported by a worldwide network of quick response and service centres.

resolution makes the QXM one of the most accurate actuators on the market. The QXM uses a brushless direct current (BLDC) voltage motor that meets most global voltage requirements. This feature is an advanced technology that helps eliminate sparks, reduce mechanical and electrical noise, and dissipate heat better than direct-current motors with brushes. The brushless motor is designed to last longer than conventional motors and allows for more accurate positioning. The BLDC motor, in conjunction with the absolute encoder, helps provide the precision that users require in their processes. The Limitorque QXM is available for multi-turn valves that require a minimum of 24Nm (18lb-ft) to a maximum of 337Nm (250lb-ft) torque, and from 3

The QXM is a smart electronic valve actuator available with either 6.5 total turns or a maximum of 20 total drive sleeve turns. This is particularly important for small valves that require limited travel and maximum control. The QXM encoder employs system- on-chip technology that permits redundant, 12-bit resolution over 20 total turns, or an accuracy of less than two degrees of drive sleeve rotation. This redundancy is part of the built- in self-test feature of all Limitorque smart actuators, and the positioning
