Protective role for control valves
In order to rule out possible cases of damage in industrial plant the operator has to fulfil a series of precautionary safety measures and regulations. These measures relate to the safety equipment, control equipment, safety distances and the regular checking of the functional capability of technical plant and equipment. The selection and design of control valves which have to fulfil a protective function must correspond to the requirements in respect of protective devices. Their suitability can be examined according to DIN V 19250 (fundamental safety considerations) and DIN V 19251 (I&C protective devices). The control valves manufactured by Schmidt Armaturen (FlowTop, FlowPro and FlowAct) can be deployed up to requirement class 7, if the corresponding requirements for avoiding faults and controlling faults are observed on the part of the plant operator. Key criteria for the classification of I&C devices are the design, configuration, assurance of quality, hardness tests and many years of proven operational reliability.
