Does your day at work involve different liquids that shouldn't mix together? Then a non-return valve can help you avoid this. It acts as an intermediary in your system. For example, if you use a good centrifugal pumpit's best to separate the clean and dirty liquids. That way, there are no complications with an installation and you can continue to use the smart pump. That's why a non-return valve is suitable for different installations.
A non-return valve is designed to ensure that a liquid can only flow in one direction. This makes it particularly suitable for installations that deal with harmful media. This way, liquids such as water are not contaminated by acids or alkalis, for example. A good quality non-return valve can also prevent water hammer in the system as it ensures a smooth flow of the fluid in question. Water hammer can damage pipes and the installation itself.
Different check valves for different needs
Does your application require a specific type of non-return valve? Then you've come to the right place. At Alflow, we have several different types of check valves for different purposes. Check valves can be categorised into different types:
- Ball check valve has a spring-loaded ball that closes against a seat
- A check valve is mounted with a swivel disc
Both types basically work in the same way. The gas or liquid flows into the inlet side of the valve and out the outlet. If a backflow occurs in the installation, the non-return valve will shut off. A non-return valve is suitable for applications with high pressure, insufficient back pressure and high flow rates.
Find the right check valve
At Alflow, we have check valves for several types of liquids. Not all check valves are suitable for all purposes. At Alflow, you can buy non-return valves that work for, among other things:
- Water
- Gas

Remember to mount the valve correctly
When a valve is installed in the system, it is important that it is orientated correctly. If the valve is not installed correctly, the liquid or gas will not be able to flow through the installation. On the non-return valve it is indicated how to correctly mount the non-return valve on the pump or pipe.
An incorrect installation of a non-return valve can also cause backflow - and that can be a problem. This results in you having to spend more time and energy pumping the same liquid or gas multiple times.
Choose good quality check valves
All of our functional valves are made of good materials, and the same goes for check valves, of course. If you don't choose a good quality non-return valve, it can leak over time, which means that you have to maintain the system to a greater extent than if you choose a good quality model. Check valves are made of stainless steel, so the valve can be used for multiple purposes. If the valve is to transport acids or alkalis, you should look for a model made of acid-resistant steel. This minimises the risk of corrosion in the installation.

What is a non-return valve?
A non-return valve ensures that a liquid can only flow in one direction. It is therefore particularly suitable for installations that deal with harmful media.
A check valve can be a ball check valve with a spring-loaded ball that closes against a seat, or a check valve that has a swivelling disc.
Both types work basically the same way, with the gas or liquid flowing into the inlet side of the valve and out the outlet. If a backflow occurs in the installation, the check valve will shut off.
Where are check valves used?
Non-return valves can prevent backflow in the installation and thus avoid contamination and mixing of liquids. They are therefore particularly suitable for installations that deal with harmful media.
Check valves can be used for water, gas, steam, acids and alkalis, among others. A non-return valve is suitable for applications with high pressure, insufficient back pressure and high flow rates.
