ABSTRACT:
An extended stroke poppet valve particularly suited for handling caustic fluids and having features enabling an extended service life for the valve. The valve includes a two part primary diaphragm assembly with a wetted diaphragm made from highly fatigue resistant fluoropolymer material, and a diaphragm backer made from high strength fluoropolymer material designed to withstand the high stress loads imposed by an extended valve stroke. The combination of these two layers in a single primary diaphragm assembly yields a highly durable, caustic chemical resistant, diaphragm capable of use in a long stroke poppet valve and having a relatively long service life.
