A foam dispensing apparatus is capable of dispensing a mixture of a resin component and an isocyanate component. The foam dispensing apparatus includes a resin line and an isocyanate line connected to a manifold. A nozzle is connected to the manifold and the mixture is dispensed through the nozzle. The manifold defines a resin duct in communication with the resin line and the nozzle and an isocyanate duct in communication with the isocyanate line and the nozzle. At least one valve is connected to the resin and isocyanate lines and is moveable between an open position allowing flow through the resin and isocyanate lines and a closed position preventing flow through the resin and isocyanate lines. The valve is disposed exterior to the manifold and the flow is unregulated in the manifold for reducing maintenance of the manifold.
