Check valves are commonly used armatures that can be applied for liquid, gases and steam applications.

Check valves provide the flows just one way. When liquid flows through to flowing direction, check valves open and let it pass. But liquid tries to flow opposite direction of flowing, check valves close and prevent passing.

Ayvaz lift check valves have big importance for all installations. They are the most important precautions against shock pressure which may cause of damage in steam lines and armatures.
