Abstract
A double-walled shear valve that carries fuel from a branch or main fuel piping to fuel dispenser piping. The double-walled shear valve comprises a containment housing defining a shear groove on the outside circumference of the containment housing and an inner housing defining an inner housing orifice therein forming a fuel flow path. The inner housing is coupled to the containment housing, and at least partially surrounded by the containment housing, such that an interstitial space is formed separate from the fuel flow path between the containment housing and the inner housing. The double-walled shear valve further comprises a main poppet valve coupled to the inner housing that is adapted to close the fuel flow path to prevent flow of fuel.
