Abstract:
A valve seat is provided for use in a rotary valve for use in highly corrosive and abrasive applications. The valve seat includes a seat body adapted to selectively engage a portion of the floating ball element. The valve seat also includes a sealing element disposed in a first groove formed in the seat body and adapted to prevent fluid flow between the seat body and the valve body. The valve seat further includes a first bearing disposed in a second groove formed in the seat body, and a second bearing disposed in a third groove formed in the seat body, wherein the second and third grooves are formed immediately adjacent the first groove such that the first and second bearings are disposed immediately adjacent the sealing element.
