RE: Definition of wear travel of gate valve
The amount of travel required to accommodate this seat wear is called the "wear travel," and the wider the seat, the greater the amount of travel possible. Therefore, the words in API 600 require the manufacturer to have seat widths that will accommodate a specified travel. Since the seat ring is chamfered on the inside and outside diameters, it is the width of the seating face on the disc that controls the amount of wear travel.
During final assembly, the valve disc is fitted to the valve body by grinding the seating surfaces. It is at this point in the process that the seat ring is verified as contacting the disc seating surface at the design location (closer to the inner edge of the disc seating surface at the stem end of the disc).
