Regulating valve system for flowing media

摘要

The system has a regulator (R) that monitors a flowing medium control parameter via a sensor (F) and actuates a regulating valve (V) via a regulating module and a control element. A valve-stroke dependent value is fed back to the regulating module and the demand-actual difference of the control parameter is fed back to the regulator. The regulating module detects a valve stroke hunting effect, from which it derives an influencing parameter with which the feedback demand-value difference value is changed. The regulating module adds a percentage of the valve stroke feedback to the difference value as an influencing parameter, whereby the added factor is varied up to an adjustable maximum value depending on a known regulating method.
