A wafer check valve is a type of check valve that has a butterfly or wafer-type disk used to open and close fluid flow. A wafer check valve has two ports that is the inlet and outlet port. The valve opens when the inlet side pressure becomes more than the cracking pressure.

The Duo-Chek wafer valve design is generally stronger, lighter, smaller, most popular sizes, making them less expensive than a swing check valve.
