Abstract
A flow control valve apparatus is provided in which a main valve adjusts the flow rate of cooling water by operating a plurality of ports and a sub-valve that operates with the main valve adjusts the flow rates of the cooling water circulating through a cylinder block and a cylinder head. The flow rate of the cooling water is variously adjusted based on the operation conditions of a vehicle.
