Detail Information
A Valve Positioner is a device accustomed to decrease or increase the environment load pressure driving the actuator before the valve’s stem reaches a “POSITION” balanced towards the output signal in the process variable instrument controller.
Valve positioners are utilized on controlling valves where accurate and rapid control is needed without error or hysterises.
Positioners are usually mounted quietly-yoke or top casing from the pneumatic actuator for straight line sliding stem control valves, and also at or close to the finish-of-shaft for rotary control vales.
For either fundamental design type, “mechanical feedback linkage” connected straight to the valve’s stem provides feedback to controller.
The procedure controller informs the positioner to “change” squeeze feedback linkage reports to the positioner confirming that the change has happened and provides a “sense” from the magnitude from the alternation in position.
