A control valve system plays a critical function in controlling the fluid flow rate, pressure, and temperature in procedures of several industries. It has to function correctly to keep operations efficient and safe, so much attention should be paid to it. However, consistent with any mechanical system, control valves are liable to degrade or wear out with time. It is, therefore, imperative to identify symptoms related to the poor functioning of a control valve system to prevent breakdowns or downtimes.
Inconsistent Process Control
Some obvious symptoms that may warrant repair of your control valve system include a condition where the process control gradually fluctuates. There can be changes in pressure, temperature and flow; this may signal that the control valve is ineffective in controlling the flow. Such disparities can lead to operational inefficiencies and ultimately degrade the standard of the finished good.
A valve with some difficulty in holding the set parameters may have some internal parts worn out, or the calibration is off, thus requiring a check and maybe replacement.
Excessive Noise and Vibration
Abnormal sound and feel in the control valve system could indicate a developing problem. The noises, in general, are produced when the valve does not fit well or if there is a tendency for cavitation to occur, which is the formation of vapour bubbles and their collapse in the liquid flow. This could cause damage to the valve and also the piping system in the long run due to the flow of the opposite direction.
In the same way, too much vibration could signal an off-balance valve, wear out the internal structure of the valve, etc. Failure to do so would mean more damages will be incurred, calling for control valve system repair within a shorter period.
Leakage from the Valve
There is no doubt that if you notice some form of leakage, this will be a clear sign that your control valve system needs attention as soon as possible. These are internal leakage and external leakage. Internal leakage is often challenging to identify since it describes a condition wherein the valve fails to shut off a fluid’s flow, leading to wastage.
On the other hand, External leakage is somewhat apparent, and you may see the fluid squirting from the valve’s body or around the O-rings. Both types of leakage point to seal or gasket failure and warrant an immediate control valve system repair to avoid system breakdown.
Sticking or Sluggish Operation
Similarly, if the control valve system has a slow response or seems to stick, the response may come from the actuator, the valve stem or internal control. A valve that is stiff to turn might affect the process control since it is not in the correct position as required every time, and in critical instances, it may pose a safety risk.
This resistance could result from face corrosion, accumulation of debris on the surfaces and mechanics. Such problems can be prevented through proper maintenance; however, if they do occur, repair is necessary to regain the system’s normal functioning.
