The principle difference between the check valve and the cut-off valve is that the non-return valve allows only one-way flow of liquid, allowing only one flow from one end to the other.

The biggest difference is the structure of the valve head and valve closing method is connected by the check valve is separated, the appearance of the cut-off valve import and export in a plane and the cut-off valve is a one-way valve, arrow shell stop check valve on the other.
