ABSTRACT:
A three-way poppet valve for directing the flow of a fluid that will permit precise, constant thickness patterns of fluid coating upon a moving surface and cause a minimum of after-drool when the coating process is ceased. The three-way poppet valve assembly is also provided with means to rapidly change the direction of fluid flow to create rapid on/off fluid deposition cycle times and facilitate the formation of minimum length coatings on a rapidly moving surface.
