Different applications for the Soft & Metal Seat of Ball Valve
Soft Seated Ball Valves
Soft seats are generally made of thermoplastic materials like PTFE. They’re great for applications where chemical compatibility is important, and where the tightest seal is the key.
However, soft seats are not recommended for process fluids that are dirty, or abrasive. Soft seats can break down in these conditions, causing the valve to leak.
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 538℃ . 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.
