Choosing the right valve – Matching function & Application


Choosing the right valve for your system can be vital to which performance efficiency and longevity. Different valve types have different functionalities and suit specific applications.

Some of most important factors that decide valve’s suitability for a particular application include how the materials used interact with the particular substance to be conveyed the amount of substance and the desired flow rate, and the overall mechanical design of the system.

Here we will take a closer at some of the most common valve types and there suitability for particular application.

Gate Valve

Gate valves are a common type of on/off function valves, that allows the flow of fluid through the system to be shut on/off via the use of a sliding part, or gate, that can be moved in/out of the path of the conveyed substance.This is particularly useful for straight line flow and when you wish to isolate a particular area of a pipe line.

Depending on the materials used in its manufacture, gate valves can be used in applications involving the convenience of both neutral and corrosive liquids, slurry, fibrous suspensions, neutral or vacuum gasses and lubricating products such as graphite and talcum.

In some cases the rectangular or round gate can also be used to regulate flow by controlling the extent of the aperture through which the fliud can move, with a fully open gate allowing for maximum flow however most gate valves are not designed for this purpose and using them this way is not recommended.If precisely controlling flow rate is your desire there may be other types of valve that better suit your application.
