Metal Seated Ball Valve

Hard surface

HVOF Treatment & others

Metal seated valves are designed for harsh working condition, such as high working temperature or media contain hard particles. HVOF (High Velocity Oxy. Fuel) can offer different hard surface materials such as Tungsten Carbide, Cobalt, Chrome Carbide for various working condition. Except HVOF process, we can offer Hard Chrome or spread welding on surface.

Single direction or Bi-direction?

For floating ball design ball valve, the benefit is better sealing ability.  The contrary side is higher operation torque under pressure. Customers need to follow the document of ZIPSON Selection Guide For Metal Seated Valve to make sure the valve will operate under the recommended pressure differential.  The operating torque may be too high if the pressure differential is over the suggest pressure, the stem or ball groove could be damage by the high torque.

BAll valve for 500°C working condition

High Temperature Ball Valve

Due to the absence of plasticized sealing materials such as PTFE (Teflon) or O-ring, sealing in this design is achieved using graphite or welding methods. These high-temperature valves are suitable for high-temperature fluids below 500°C or for use in high-temperature working environments.

Common applications for these valves include high-temperature steam and thermal oil, making them a convenient and practical choice.
