Trimteck Positioners

Introduction to Positioners.

A positioner is a device attached to an actuator that receives an electronic or pneumatic signal from a controller and compares that signal to the actuator’s position.

If the signal and the actuator position differ, the positioner sends the necessary power—usually through compressed air—to move the actuator until the correct position is reached.

Trimteck manufactures a comprehensive line of Optimux globe control valves – and a variety of actuatorspositionerssevere service trims and other accessories – that our applications engineers and representatives use to solve the most complex flow, pressure, and temperature control challenges quickly and economically.

At Trimteck, we are obsessed with quality.
