Type 2000 Valve Positioners (Pneumatic and Electro-Pneumatic) are mechanical devices designed to provide enhanced control, stability, and shut-off capability in extreme flow applications. The positioner, which is mounted to the valve’s yoke assembly and linked to the valve stem, receives a signal from an external control source, compares the control signal to the actual position of the valve plug, and then sends a corrected signal to the valve’s actuator, thereby positioning the valve plug for optimum flow modulation.
The Pneumatic Positioner receives a 3-15 PSIG air signal normally takenfrom an I/P Transducer.
