Valves are used for different kinds of functions in machines that we see around us and in industrial application. If we talk about check valves, we will see that they are mainly used in residential or less complicated usage applications as they are non-return valves allowing the movement of fluid in only one direction. On the other hand there are butterfly valves which find usage in industrial environments as they are used for regulating the flow in large pipe diameters. They are preferred by a number of clients as they aren’t just cost effective but are also light in weight. This allows them to be placed in a number of situations.
What are butterfly valves?
There are different kinds of butterfly valves including resilient seated butterfly valve, PTFE lined, high performance, triple offset, double eccentric and grooved. As discussed above, these valves are used for regulation of flow in case of pipes that have large diameters. So their construction process is also required to be different than the usual. Being lightweight you don’t have to think of an additional support for the valve when you are using it. A seat and a disc are the main components and how they are used depend on the specific purpose of the valve.
Use and range of check valves
In comparison to the other kinds of valves, especially the one discussed above, these valves are available in a comparatively lesser number of variations. There are only four kinds required to serve the function — cast iron, cast steel, forged steel and stainless steel. Cast steel valves allow flow in one direction and the valve closes as the flow reverses while in case of cast steel valve, it is used to prevent the reversal of flow in either horizontal or vertical lines. In case of forged steel valves you can get it in two variations — bolted and welded bonnet types. You can get four variations of stainless steel check valves including dual plate, single plate, wafer lift and threaded valves.
There are purposes for both of the above types of valves and there are manufacturers who supply all these different kinds of valves so that they can reach out to a maximum number of clients around the world. Check valves and butterfly valves find a wide range of applications and valve manufactures answer to the demand of a customer for quality valves priced reasonably.
It’s not too difficult to find the valves if you get to it, but the challenge lies elsewhere. When any product or service is widely available, customers have no dearth of choices. This means that they can depend on cheaper alternatives and often end up compromising with the quality of the product. The point is when you are buying valves, be it check valves or butterfly valves, there needs to be a balance struck between quality and price so that the investment is worth the effort. It should be ensured that the quality standards of manufacturing and raw materials are complied with. This will ensure that you get durable and efficient valves.
There are different kinds of butterfly valves and check valves available which you can source from one of the best manufacturers.
