A check valve having a faceplate and an insert assembly. The faceplate and insert assembly have a stepwise cross-section in the direction of a forward fluid flow through the check valve. The stepwise cross-section is designed for placement of the faceplate and insert into a complementary shaped valve body. The faceplate defines at least two sections through which the fluid flowing through the check valve flows. The moving parts of the check valve, doors and hinges, are mounted on the insert such that the parts are not impacted by the fluid flow, thereby reducing maintenance on the check valve. Maintenance on the check valve can be accomplished by simply removing the faceplate, thereby releasing the insert assembly from the valve body so that the insert assembly can be replaced with minimum downtime to a cooling system having this check valve installed.
