# Valve bodies having wear resistant inner cores

## 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.
