Small, simple and inexpensive, that are some of the key attributes with which you can describe the non return valves. The primary function of these valves is to enable fluid to flow only in one direction.

They are extremely in demand and used within the industry. One thing that needs to be kept in mind is that there are different types of non return valves available in the marketplace and not all of them look and work in the same way. They are used under varied circumstances.

We at Dutco Tennant LLC supply high-performance non return valve solutions that are designed to assist expansive potable water projects and more. If you are interested to know more about this project solution then make a stop at this year’s WETEX 2022 where Dutco Tennant shall exhibit.

You can find this product at Hall H7, Stand no. 7-B12 of the exhibition. But before you visit the event, here’s a quick guide for the selection of a non return valve. Keep reading till the end to find out more.

Non Return Valves - What are they?

Non return valves are valving solutions that are designed to prevent backflow of fluid flow. While there are many types of non return valve, their function at the core happens to be the same.

As they work to keep the fluid flow in one direction, they are also known as One-Way Valves. They are commonly categorised under two-port valves as they typically have two openings - one to act as exit for the fluid and the other for their entering.

Most non return valve solutions don’t require manual assistance for operating and are automatic. Therefore, they are mostly available without any handles or stems.

Different Types of Non Return Valves

Lift Check Valves

This type of valves are frequently used in high pressure service applications and when there is high-speed fluid flow. Here the piston disc is accurately target-hunting by the thick walls of it and long contact and dashpot are more or less equal.

Folding Disc Check Valves

These are made in a wafer-body pattern and are known for having lightweight compact structure. These characteristics make them the suitable choice when acreage and convenience is required for the applications.

There are other various types of non-return valves in the marketplace with varied designs and operating mechanisms.

Importance of Selecting from Varied Types of Non-Return Valves

As we see that non-return valves come in different shapes and sizes, they also happen to be inexpensive and small compared to other valving solutions. The use of an ideal non return valve helps in defending the compressor equipment and pumps from harm. 

Reverse flow or backflow fluids can impact the components within the system and can also contaminate if the system carry’s potable water. These can be minimised with the use of suitable type of non return valves only.

For more information on non return valves make sure to stop by the Dutco Tennant LLC exhibit at WETEX 2022 this year. Event starts from 27th September where you can get the chance to witness and explore this valving solution up close.
