Abstract
A gate valve for use in a high pressure line has a movable gate and a static seat within a valve body. The seat has a seat face which is in sliding contact with a gate face. The seat and gate faces are coated with an amorphic coating which hardens when the seat face and gate face are subjected to manufacturing processes or rubbed together during valve opening and closing. A leak resistant seal between the seat and gate faces results when the valve is closed and subjected to high line pressure.
