A control valve body includes a valve seat containing multiple metal pipes and valve chamber; both ends of each pipe being respectively disposed with a water inlet and a water outlet to connect through those chambers; one or a plurality curvature being provided to the pipe between the water inlet and the water outlet; and the valve seat being clad with an outer layer to provide a hard-wearing and production cost saving control valve body construction due to the inherited heat resisting and durable properties of metal pipe.
