A flow control valve which does not utilize any moving components in the valve is disclosed. In the flow control valve, a valve housing that has a cylindrical-shaped wall is first provided. Inside the valve housing, is then provided a first and a second end plate for sealingly engaging an inner periphery of the valve housing. The first and the second end plate are positioned spaced-apart in a predetermined distance while each of the end plates has at least one aperture therethrough for the passage of a fluid flow to be controlled. Inside a valve cavity formed between the two end plates and the inner periphery of the valve housing is positioned an inflatable bag such that when a fluid is flown into the inflatable bag, the bag inflates to either partially block or completely block the fluid passageway through the valve cavity.
