The main advantage of metal to metal seat check valve is their ability to withstand high temperatures and harsh conditions of use. Metal seats can withstand severe flashing, hydraulic shock, abrasive process fluids and high temperatures up to and exceeding 1,000 °F.
They are also ideal for high corrosion or corrosion applications. Metal seats can be hardened by ultrasonic spraying, hard surfaces such as satellite hard surfaces, chromium carbide and tungsten carbide.
