Abstract: Example valve bodies having resistant inner cores are disclosed herein. An example method includes forming a monolithic inner core of a valve body using a first material. The monolithic inner core defines a flow path of the valve body. The monolithic inner core has a thickness that varies between a first wetted portion of the flow path and a second wetted portion of the flow path different than the first wetted portion. The monolithic inner core provides erosion and corrosion resistant characteristics against process fluids. The method further includes overmolding an outer shell of the valve body to the monolithic inner core, the outer shell including a second material different than the first material.

Abstract: A test device and method of this disclosure maintain stable bath temperature of a calibration bath. The test device includes a base that introduces vortex flow of liquids from the calibration bath into a hollow interior of a cylinder containing a reference and a test thermometer, the vortex flow of liquids then exiting a cap at the upper end of the cylinder and returning to the bath. The test device is partially surrounded by the liquids of the calibration bath. In some embodiments, the calibration bath is a circulating calibration bath. The test device and method of its use maintain bath temperature within at least ±0.01° F. (±0.0056° C.) about a predetermined bath working temperature.

Abstract: Example valve bodies having resistant inner cores are disclosed herein. An example valve body comprises a metal core including a fluid inlet, a fluid outlet, and a fluid passageway extending between the fluid inlet and the fluid outlet, and an exterior shell overmolded with the metal core, the exterior shell bonded to the metal core, the exterior shell to provide a pressure-boundary of the valve body.
