What should an operator do if they suspect a valve is not functioning properly?

When an operator suspects that a valve is not functioning properly, the correct course of action is to check for leaks and verify operation. This approach helps determine the precise nature and extent of the issue before taking any further steps. Checking for leaks ensures that there is no fluid escaping, which could indicate a malfunction that affects system performance or safety. Verifying operation allows the operator to confirm whether the valve is acting as intended, whether it is stuck, or if there is another issue at play.

Taking immediate action to repair the valve without understanding the problem could lead to further complications or even exacerbate the situation, especially if the operator is unsure of the specific malfunction. Similarly, simply replacing the valve may not be necessary if the problem can be resolved through inspection and potentially simple repairs. Ignoring the situation entirely until a scheduled service could lead to unexpected failures and potentially hazardous situations. Therefore, the most prudent and effective step is to conduct checks and verify the valve’s operation.
