What is a tilting disc check valve?

The disc of a tilting disc check valve has a pivot point at the center of it. It is desinged to overcome weaknesses of general type swing check valve.

Compared to swing type check valve, the tilting check valve could remain fully open and steady at lower flow rates. That is to say, the swing check valve needs a high velocity of fluid to keep disc open and a higher cracking pressure.

For low pressure situation, the pressure drop of a tilting disc check valve is much lower than the swing type. But at a higher flow rate, the tilting check valve has higher pressure drop than swing type.
