New Limitorque actuator

The new Limitorque QXM is 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.
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.
The QXM utilizes an innovative brushless direct current (BLDC) voltage motor, a design that 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.
