And, above all: What can we expect in the future? Here are some answers to these questions.

check valves

The role of check valves in piping systems

Check valves are vital fluid control components in piping systems that serve various critical applications. These devices prevent backflow and the numerous problems associated with it. In certain applications, they are also used as vacuum breakers. Check valves can be found in water, sewage, gas, chemicals, and other piping systems.
