The purpose of online testing is to monitor and exercise the valves when they are in use. Val Controls online testing consists of Partial stroke test (PST), full stroke test (FST) & solenoid test (SOV).
Partial stroke testing is used to test a certain percentage of shut down valves. The advantage of PST is that it allows operations to continue as the need to physically close the valve is eliminated.
Full stroke testing closes the valve completely and is only used during shutdown or before installation.
Solenoid testing is used to test the open/close mechanism of an electro-mechanical valve.
The advantage of Val Control's online testing solution is that the end-user can diagnose the valve while it is in use. Furthermore, the solution provides the possibility of comparing the current performance data with the optimal reference data.
