Available now from Acrodyne , the new Limitorque QXM is a smart electronic 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.
The Limitorque QXM electronic valve actuator is 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.
These electronic valve actuators feature encoders that employ system-on-chip technology to permit 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 Limitorque QXM electronic valve actuator utilises an innovative brushless direct current voltage motor that helps eliminate sparks, reduce mechanical and electrical noise, and dissipate heat better than direct current motors with brushes. Designed to last longer than conventional motors and allow for more accurate positionin, the brushless direct current voltage motor, in conjunction with the absolute encoder, helps provide the precision users of the Limitorque QXM smart actuator require.
