Abstract
A valve assembly having a valve body, a hardened insert, a sealing insert, and a carrier. The hardened insert is cylindrical and comprises a primary sealing surface. The sealing insert is cylindrical and comprises an initial sealing surface. The carrier has an inside surface. The hardened insert and the sealing insert are coupled to the carrier. In a closed configuration of the valve assembly, the valve body contacts the primary sealing surface of the hardened insert and the initial sealing surface of the sealing insert to prevent fluid flow through the valve assembly, and in an open configuration, the valve body is separated from the primary sealing surface of the hardened insert and the initial sealing surface of the sealing insert to allow fluid flow through the valve assembly.
