1. A valve comprising:
a valve body having a fluid pathway defined through the valve body, the valve body being formed of a metal material defining a first seating surface;
a valve member received in the valve body and defining a second seating surface, the valve member being movable relative to the valve body in order to at least partially obstruct the fluid pathway when the second seating surface of the valve member contacts the first seating surface of the valve body; and
at least one flushing feature comprising another fluid pathway defined by the valve body that extends to a location proximate at least one of the first seating surface or the second seating surface and terminates in openings defined proximate the at least one of the first seating surface or the second seating surface, the openings of the at least one flushing feature configured to supply fluid to the at least a portion of the valve through the first seating surface along the another fluid pathway that is at least partially separated from the fluid pathway of the valve body, the at least one flushing feature configured to at least partially displace material from at least one of the first seating surface or the second seating surface.
