Abstract: A gas distribution valve including a body defining an inlet and an outlet passage, a central well containing a cylindrical plug disposed for arcuate displacement therein and including a transverse thru-bore that can be rotated into and out of axial alignment with the flow passages of said body for opening and closing the valve respectively. Overmolded elastomeric seat seals are provided for superior sealing that are urged against the well walls by an arcuate leaf spring intervening between the seals and the plug and extending in a direction concentric with the plug. A cover plate secures the plug within in the well and there is afforded a fire seal ring providing bi-directional contact sealing operative to restrict gas flow during and after exposure to fire or other high temperature environment.

Abstract: A pipeline strainer having a body defining a rectilinear flow passage between an inlet and an outlet and a cylindrical cavity centrally located therebetween. A removable cover of cup-like configuration is secured in a sealed relation to the body subtending the body cavity in which a dual layered strainer assembly is supported in the flow passage in a sealed relation between an interior surface of the cover and an interior surface of the cavity.
