Useful Guidelines on China Check Valve

We should start by saying that check valves flow in a single direction and they are designed to prevent back flow when fluid reverses its direction. This type of valve can be used without requiring any help to open or close. This means that your China Check Valve will continue to function even when there is no air, electricity or the possibility for manual operation in your plant. What most people do not know is that check valves are commonly used pretty much everywhere in residential as well as commercial and industrial applications.

As far as the media you can use check valves with, we should mention the following: liquids, air, other gases, steam, condensate and even liquids with fines or slurries. When it comes to applications, we should mention header lines, steam lines, condensate lines, chemical feed pumps, cooling towers, boilers, HVAC systems, utilities, pressure pumps, wash-down stations and injection lines. As you can see, they are used in an impressive selection of applications.

The China Check Valve is flow sensitive, it has a simple construction and its main components are body, seat, disc and cover. More complex designs have additional items such as stem, disc arm, spring, ball, bearings and elastomers. It is recommended to opt for valves with elastomers for applications with air/gas media with low-pressure sealing. What most people tend to ignore is that regardless of the type of valve they tend to opt for, what matters is that the valve they choose is of suitable size for its intended application. This will save you from unpleasant surprises and provide a long trouble-free service.

Also, it is important for the disc to be stable against the internal stop in the open or fully closed position to ensure that fluttering of the disc does not occur. The most common mistake most people make is that they choose their check valves based on the line size and based on the need of having a large Cv. With this type of valve, the flow condition is responsible for the performance of the check valve. In situations where there is not enough flow disc movement occurs and this leads to the wear of the valve and potential for failure.

Component failure will affect the overall performance of the valve and this is something you should avoid at all costs. It is best to contact your Check Valve Manufacturer and tell him what you need so that he can make adequate recommendations that meet your exact requirements. We should also mention that there are different types of check valves available on the market such as the ball, dual plate, spring-assisted in-line or nozzle or silent, piston or lift and swing check.

If you have special application requirements you should not hesitate to inform your Check Valve Manufacturer about them for, he will do his best to cater to your needs. Last but not least, when shopping for check valves you should consider the following: material compatibility with the medium, line size, valve rating, application data, installation, end connection, envelope dimensions, leakage requirements and special requirements if any. You can avoid check valve problems by choosing a suitable type of valve.
