Ball Check Valve: Non Return Valve

The ball check valve reliably prevents backflow of the medium and is also suitable for contaminated media thanks to the check ball, which clears the entire passage. For this reason, ball check valves or ball backflow preventers are often used in the wastewater sector. We carry these valves with different body materials and ball coatings (EPDM, NBR, PTFE, Viton). There is a wide range of check valves of different designs, materials, and applications.

Ball Check Valve

A ball check valve, also known as a non-return valve or backflow preventer, is a device used to prevent the backflow of liquids or gases in a pipe system. The ball check valve uses a ball or other moving mechanism to allow flow in one direction and prevent flow in the opposite direction.

Do you have questions about ball check valves?

Here you will find some answers to questions about the ball backflow preventer. If you need further help, please contact our customer service.

Question: What is a ball check valve and how does it work?

Answer: A ball check valve is a device used in pipework systems to prevent the backflow of liquids. It consists of a housing with a ball valve that can move freely. When the liquid flows in the desired direction, it pushes the ball away and releases the flow. However, in the event of a backflow, the ball is forced into position by the opposing pressure, blocking the flow and preventing a backflow.

Question: Where are ball check valves normally used?

Answer: Ball check valves are used in various areas, e.g. in drinking water supply, industrial processes, the chemical industry, food processing and in heating and air conditioning systems.

Question: Why is the use of ball check valves important?

Answer: The use of ball check valves is important to prevent contaminated water from entering drinking water systems or hazardous chemicals or contaminants from flowing back into production processes and causing damage. They also help to maintain the integrity of pipework systems and make operations safer.

Question: Are there different types of ball check valves?

Answer: Yes, there are different types of ball check valves that can vary depending on the application and requirements. These include spring-loaded ball check valves, pressure relief valves, double ball valves and others. Each type has specific features and areas of application.
