A novel valve assembly is provided. In one embodiment, the valve assembly includes a seat plate that includes a fluid conduit and an impact bushing that is coupled to the seat plate at a position adjacent to the fluid conduit. The valve assembly also includes a sealing assembly that is configured to form a seal with the impact bushing and to control flow of a fluid through the fluid conduit via relative displacement of the sealing assembly from the impact bushing. Systems and methods related to such a valve assembly are also disclosed. Data supplied from the esp@cenet database-Worldwide.
