Why Control Valves Make Annoying Noises

Control valve noise

Are you looking for ways to reduce the annoying noise generated during the operation of control valves in fluid flow measurement and control applications? Control valves are one of the most widely used instruments in these applications and play a vital role in compensating the load disturbances caused by steam, gas, or water flowing through a pipe and maintaining the level of process variable close to the desired set point.

But, a lot of noise is generated during the operation of these control valves. Do you know what causes this noise and how to control it? Read on to find out!

This post provides detailed information on the causes of noise generated by control valves and how to reduce it. We also discuss some of the noise control methods you can use to achieve a noise-free control valve operation.

Don’t let the noise disrupt your fluid flow measurement and control applications – find out how to reduce valve noise and maximize their performance!

Operating Control Valves Produce an Exasperating Noise for a Variety of Reasons. How can You Get Rid of it?

There can be different reasons behind this noise. However, here are some most common causes and remedies:

Remedy: The only surefire way to tackle the noise problem is by reducing the resonance. This will decrease the intensity of the noise, though it may not eliminate it. However, reducing the resonance can make a world of difference in reducing the amount of noise you hear.

Remedy: If you’re dealing with an exasperating noise caused by cavitation, eliminating the source is the best way to address the problem. Try to reduce or eliminate the cavitation as much as possible, as this will help reduce the noise from the operating valves. Taking the necessary steps to eliminate the cause of the sound will ensure that you can enjoy a quieter, more peaceful environment.

Cause No.1 The leading cause of the noise is vibration, and if the control valve has poor resonance, the intensity of the noise can be extremely high. By ensuring that the control valve has good resonance, you can help to reduce the amount of noise produced. Additionally, regularly checking and inspecting the valve can help identify potential issues and ensure it’s in good condition.

Cause No.2 Another possible cause of this noise could be cavitation, which is referred to as the flow of the control valve, creating a speeded force. This speeded force is what gives rise to the noise. Cavitation occurs when the bubbles of the medium burst, creating an increase in pressure which can create a loud, distinct sound. If you notice this sound coming from your control valve, it may be time to check it out, as it could be a sign of a malfunction.

There are a few more solutions for eliminating the problem of annoying noise apart from those mentioned above. These solutions are as follows:

  • Thickened Pipe:This is one of the most effective ways to eliminate this problem as it can reduce the irritating noise. However, it comes with a cost, as the thickened pipe is costlier than regular pipes.
  • Series Flow Method:Implementing this method can also help reduce the noise by a considerable amount.
  • Sound-absorbing Material:Surrounding the valve pipe and the noise source with sound-absorbing material is also an effective way to reduce the noise’s intensity.
  • Low-Noise Valve:Last but the easiest and most effective way to eliminate the problem is to use a control valve that has a low-noise rating. This will help reduce the noise significantly and make the environment more peaceful.
