K-10

The Westlock K-10 electro-pneumatic positioner accepts variable instrumentation signals (between 4 and 20 milliamps) from a PLC, DCS, set point controller, etc. and regulates the 80-psi air supply to and from the actuator. This process regulates the actuator position within its quadrant for precise modulation.
