Method and system for function testing a valve |
摘要 |
In a method or system for function testing of a safety valve in engineering plant, it is tested whether the safety valve travels from a normal position to a predetermined final position in a certain operating situation of the plant. A bypass the valve bypasses the safety valve and assumes an idle position in a normal operation of the plant and a predetermined test position for function testing of the safety valve. The test position of the bypass valve is established such that a predetermined fluid flow through the bypass valve is permitted.
