This produces a control valve of an appropriate size and type that will best meet the needs of managing flow within the process system.
Every attempt should be made to carefully and accurately size and select a control valve for the required application. The topic of control valve selection.
Control Valve Selection Febru James McLoone. A previous blog-post discussed the importance of control valve sizing and energy optimization opportunities. This blog-post will focus more on the topic of control valve selection although, both .Q: Why is cavitation in particular an important factor to consider during the valve sizing and selection process?
A: Cavitation is important to consider because the high velocity of liquid can create low-pressure bubbles of air that result in an explosion and can cause pitting of the metal, especially in the orifice area of a valve. Pitting may lead to the erosion of the metal.Q: For many applications, valve sizing and selection will determine the ultimate success or failure of the larger process.
In your opinion, what are some key steps end-users can take to ensure the proper sizing and selection of valves? A: For the purpose of the following line of questions, let’s define the type of valves we are discussing.
