This assessment according to SIL covers the functional safety of the products and is used to evaluate the systems in relation to the reliability of fail safe functions. The result is safety-relevant design principles which must be complied with in order to minimize the risk of a malfunction. SIL itself is a measure of the probability that a system will correctly fulfil the required fail safe functions for a specific time period.
In addition to pilot valves, the GEMÜ products assessed include globe and diaphragm valves and electrical position indicators.
By assessing the product selection referred to here, GEMÜ is complying with its customers' requirements primarily from the process and manufacturing industries. With the data made available, these can now carry out assessments of entire plants.
