The Siemens Moore 73 compact pneumatic valve positioner incorporates a single-axis, force-balance principle of operation to ensure accurate and stable control valve positioning. In all cases, including bottom-loading applications, the Model 73 Built-In Pneumatic Valve Positioner is mounted directly on the top work of the valve, with no external levers or other exposed mechanisms.
Like all valve positioners, the Model 73 Built-In Valve Positioners have feedback circuits designed to measure the position of the actuator's piston or diaphragm. The positioner then supplies or exhausts air to bring the actuator within the required range for its corresponding control instrument.
By selecting the appropriate range spring from the wide selection, almost any combination of valve stroke (from 1/4" to 4") and instrument span (from 2 to 24 psi) can be obtained.
