The Partial Valve Stroke Test - Insights

A Partival Valve Stroke Test (short: PVST) enables the operator to check and guarantee the safety of the system without interrupting the process. Here, the valve is only partially closed (by 5% up to around 20%) and thus some of the possible sources of error are tested, especially with safety shut-off valves. The functionality is checked during operation if required without interruption of flow.
