A
check valve is a
one-way valve designed to
prevent backflow and allow fluid to flow in only one direction. It automatically closes if the flow reverses, preventing damage to pumps, pipelines, and other equipment.
Common Applications of Check Valves:
·
Water supply systems – Prevents contamination due to backflow.
·
Pumps and pipelines – Protects against reverse flow that can damage equipment.
·
Compressed air systems – Ensures air flows in the correct direction.
