The importance of using check valves stays strong always in various types of applications ranging from water supply to industrial ones. The main reason for using check valves in the systems is to avoid fluid backflow that can otherwise contaminate the fluid upstream or even damage your equipment. Before you make any decision to purchase check valves, try to get information about the valves and use them as per your need and application. This blog can help you to offer you the details of check valves and how they work.
What are check valves and why are they vital?
When the fluid flows in the reverse direction, the users need to install check valves. These valves can enable the fluid to flow in one direction and help in preventing fluid backflow. You must know that reverse backflow in water supply system projects or many other treatment plants can have serious and adverse effects. For this reason, the instalment of check valves becomes extremely vital for these systems. Check valves are one of the most used self-automated valves which can be easily closed or opened without help. Check valves will always remain to be a major component in the plants as they do not need any kind of external electricity for operation due to their dependence on the loss of pressure induced by the flow of fluid.
Why are check valves used?
Check valves are used majorly in those types of applications where the fluid backflow is one of the greatest issues. As check valves are non-return valves that are effective, simple and less costly for this big problem, people prefer check valves as compared to other valves when they want to avoid reverse backflow. Backflow of fluid can be a disaster if the fluid is contaminated and that can contaminate the particular fluid upstream. You can get check valves of different designs, materials and sizes in the market.
What are the major applications of check valves?
As mentioned earlier, backflow can be prevented well with the help of check valves. These valves are installed frequently as support in those events when the pump fails, to reciprocate pumps, to aid compressors, or when the system’s pressure increases the capacity of your primary equipment. You can find check valves used in different sectors which mainly include water supply systems, water management projects etc. This type of valve is also used in multiple sectors like petrochemical, refineries, oilfield operations, stream fluids and many more. When we talk about wastewater treatment and related industries, check valves are very predominant there too. Another sector that is not far away from the usage of check valves – is the food & beverage sector. Even in maintaining the safety issue of industries, check valves need to be deployed.
Do you want to acquire more information about check valves and attend amazing seminars relating to this type of solution? You are welcome to the WETEX exhibition 2022. Dutco Tennant LLC will be showcasing top-class products which can be the best and unique for potable water project needs. Do not miss this chance to meet us from 27th to 29th September 2022 at Hall: H7, Stand no. 7B12.
How do the check valves work?
Now let us, deep dive, into the working principle of “check valves” in detail. Check valves operate on the differential pressure between the outlet and inlet of valves. In order to open the check valve, they need a high pressure on the input side as compared to the output side. The closing mechanism of check valves varies. It depends on the kind of valves you are using. Unlike other types of valves, they do not need any lever actuator, handle or persons to operate properly.
Take into account:
Cracking pressure: The cracking pressure of check valves is the minimum upstream pressure when the check valves open. Particular cracking pressure can vary depending on the design & sizes of check valves.
Closing of check valves: Check valves close when the upstream pressure decreases than the cracking pressure or there is any back pressure. You can assist the closing mechanism process through gravity or spring.
Installation process: Usually, one arrow on the check valves is always there to indicate the direction of fluid flow and if not, you can inspect these valves.
Conclusion
So we hope you have got an idea about the check valves. If you want to prevent the reverse flow of fluid and provide protection to the compressor devices, pumps, meters and other tools from severe reverse flow, then use check valves. These valves can help in reducing the production loss and downtime caused by unsuitable valves. Get in touch with any best suppliers of check valves in the UAE.
