Pneumatic Positioner
The selected positioner is the pneumatic Moore Products 73-series positioner which operates on
3-15 psi (0.2-1.0 bar). A transducer can be readily adapted to handle an I/P conversion from a typical 4-20 mA.
Close Coupled
The design is close-coupled and allows for direct air loading from the Moore positioner to the upper actuator chamber in Air to Open-Air to Close and Fail Open Actuators.
Visual Position Indicator
The transparent tubing and red spring disc allows for visual position verification.
