Rückschlagklappen
Rückschlagklappen, also known as check valves or non-return valves, are mechanical devices designed to allow fluid to flow in only one direction. They prevent backflow, which is the reversal of fluid movement. This directionality is crucial in many industrial, domestic, and automotive applications to protect equipment, maintain system integrity, and ensure safety.
The fundamental principle of operation for most Rückschlagklappen relies on the pressure differential of the fluid.
There are various designs of Rückschlagklappen, each suited for different purposes. Common types include swing check
