Abstract: A method of manufacturing a valve with a corrosion-resistant barrier includes providing a valve body defining a first end, a second end, and a body bore extending from the first end to the second end, the valve body further defining a channel co-annular with the body bore, the channel comprising an outer edge defining a seat retention groove; and thermal spraying a corrosion-resistant barrier over the seat retention groove, the corrosion-resistant barrier defining a first edge and a second edge, the first edge oriented between the seat retention groove and the first end of the valve body, and the second edge oriented between the seat retention groove and the second end of the valve body.

Abstract: Example aspects of a valve are disclosed. The valve can comprise a valve body defining a first end, a second end opposite the first end, an inner surface, and an outer surface, the inner surface defining a body bore extending from the first end to the second end and a channel extending radially outward from the body bore, the channel defining a seat retention groove; a metal barrier applied to the inner surface and covering the seat retention groove, the metal barrier defining a first edge and a second edge, the first edge oriented between the seat retention groove and the first end, and the second edge oriented between the seat retention groove and the second end; and a valve seat positioned within the channel.

Abstract: Disclosed is a valve comprising: an annular body defining a body bore having a bore axis, the body further defining a channel coannular with the bore, the channel comprising an axially outer edge defining a seat retention groove, the seat retention groove comprising a metal barrier; an annular valve seat positioned in the channel, the valve seat comprising a radially inner surface; and a valve element positioned in the bore and coupled to the body, the valve element comprising a rotatable disc configured to rotate about and between a closed position, in which the rotatable disc is configured to prevent fluid from flowing through the valve, and an open position, in which the rotatable disc is configured to allow maximum fluid flow through the valve, the radially inner surface of the valve seat configured to seal against the rotatable disc in the closed position.
