Backflow is a common problem that can happen in any commercial and industrial facility. Backflow of any medium is discouraged because of the issues that it gives rise to. The use of an ideal backflow prevention device is installed in systems.

Check valves are one of the backflow prevention solutions that are used in applications where backflow is a concern. If you are interested to see this solution up close then you can visit the Dutco Tennant LLC exhibit at the ADIPEC 2022 this year. Starting from 31st October 2022, quality check valves that are suitable for Oil & Gas industries will be showcased in Abu Dhabi National Exhibition Centre where the event will be held.

But before you go and check out the exhibition, here’s a quick guide to learn about backflow and the importance of their prevention. Keep reading till the end to find out more about it.

How Does Backflow Happens?

Backflow happens primarily because of one of the two circumstances - back-siphonage and back-pressure. Back-siphonage situation occurs when the contaminated high-pressure media pulls into the system because of the low pressure area.

On the contrary, a back-pressure scenario happens when the media pushes into the system. Both of these circumstances are extremely undesirable and can cause several negative effects within the system.

The Importance of Backflow Prevention

The primary reason why backflow needs to be prevented is to avoid any contaminant or impurity to enter in the media flow because of the reverse flow. In potable water supply systems and water distribution networks the use of check valves are pretty prominent in order to keep the flow of water in one direction.

The reverse flow can cause contaminants to get mixed with the freshwater supply that has already travelled through the valve to transport into the distribution area. Additionally, backflow is also prioritised to be prevented in the systems as they are pretty aggressive in nature due to which they have damaging effects within the pipeline.

Check Valve for Backflow Prevention

A check valve, also known as a one-way valve, is a device that keeps the media flow movement only in one direction. The main purpose of a check valve is to prevent backflow in the system where it is installed. Check valves are effective, cheap and an overall easy solution to such potential issues.

Backflow can lead into a problem if the flow is contaminated and, therefore, ultimately contaminates the upstream media. For instance, a sewer line will have an installation of a non-return valve to make sure that waste can leave from the valve but not get into the system again from where it came from.

There are different materials, sizes and designs available to ensure there is a suitable check valve for every application. Most commonly the two-way check valves are used. Also, check valves equipped with vents are used as three-way check valves that help in protecting the incoming water supply from contamination caused by backflow.
