    A control valve is a power operated device capable of modulating flow at varying degrees between minimal flow and full capacity in response to a signal from the controlling system. Control valves may be broadly classified by their function as “on-off” type or “flow regulating” type.   Brief description about sizing consideration of valves in process industries & selection as per control strategy.

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.
