Sticking Solenoid Valve

Sticking Solenoid Valve

The graphs illustrate a system where the SOV is operational but performance has degraded.

The black graph is offset to the right of the red graph because the horizontal section relating to the switching of the solenoid (as shown within the blue oval) is extended. The SOV has taken longer to switch state than it had previously. The SVM system measures this to a millisecond, allowing the user to
easily set a threshold for the required performance of the solenoid before a fault is reported.

In addition to the solenoid, if there are any pilot, shuttle or quick exhaust valves, these will also be monitored in this section of the graph.
