What’s the advantage of the metal seat ball valve?
Metal Seated Ball Valves :
The primary advantage of metal seated valves over soft seated valves is their ability to withstand high temperatures and severe service conditions. Metal seats can endure severe flashing, hydraulic shock, abrasive process fluid, and high temperatures up to and exceeding 1,000° F. They are also ideal for high erosion or corrosion applications.
Metal seats can be hardened by coatings like ultrasonic spray coating, satellite hard facing, chromium carbide and tungsten carbide.
