Valve Ball Seats

Overview

For service with severe flashing, hydraulic shock, high temperature or abrasive media. Typically we hard face a stainless steel seat with Stellite then lap the ball to the seat for tight shut-off. Depending on the valve and trim we can achieve temperatures in excess of 500°C for metal seated ball valves.
