Siemens Industrial Controls 73N-B Valve Positioner

The Siemens Industrial Controls 73N-B Valve Positioner is an electronic device that accurately controls the movement of valves in heating, ventilation, and air conditioning  systems. This assists in preserving the ideal level of pressure, temperature, and airflow within the system by making sure the valve opening or closing perfectly corresponds with the signal provided by a controller. The positioner operates by continuously comparing the controller's intended valve position signal with the valve's actual position feedback. The positioner automatically adjusts any mismatch by communicating a corrected signal to the valve actuator. Precise control over the HVAC system is promoted by this continuous feedback loop, which makes sure the valve reaches and maintains the precise position required by the controller.
