Abstract
A valve assembly includes a valve body, a seal, and a supplemental material. The valve assembly configured to reduce the effects of wear and erosion of the seal and valve body by including material with increased hardness. The supplemental material has a higher hardness level than the valve body and is inserted on the contact surface of the valve body. The seal can include a plurality of materials, each having different hardness levels. The location of the supplemental material can vary and the overall radial distribution on the contact surface may vary.

A valve assembly, comprising:
- an annular valve body having a first hardness and formed of an upper surface, a bottom surface spaced apart from the upper surface, a lower contact surface extending from the bottom surface and angled towards the upper surface, and an outer peripheral edge formed between the upper surface and the lower contact surface;
- an annular seal disposed on at least a portion of the peripheral edge;
- at least one cavity formed in the annular valve body along the angled lower contact surface;
- and
- a supplemental material insert disposed in each cavity formed in the lower contact surface, the supplemental material insert having a second hardness that is greater than the first hardness.
