Flowserve Corporation introduces 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.
Important features of this actuator include:
- 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 especially important for small valves that require limited travel and maximum control.
- The QXM encoder employs system-on-chip technology, which 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. This positioning resolution makes it one of the most accurate actuators on the market today.
- The QXM utilizes an innovative brushless direct current (BLDC) voltage motor. This motor design meets most global voltage requirements. This unique 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 users are demanding in their processes.
The Limitorque QXM is available for multi-turn valves that require a minimum of 18 lb. ft./24 Nm to a maximum of 250 lb. ft./337 Nm torque and from 3-24 RPMs. For more information about Limitorque QX actuators, please call Flowserve at 972-443-6500 or visit www.flowserve.com.
