Metal sealed ball valve is a specially designed valve that can provide reliable sealing performance in high temperature, high pressure, and media containing solid particles. The following are the key points for product selection of metal sealed ball valves:
1. * * Structural form * *: Metal sealed ball valves are divided into two structures: floating ball valves and fixed ball valves. Floating ball valves are suitable for small to medium diameters, while fixed ball valves are suitable for large diameter applications.
2. Material selection: Different materials such as carbon steel, stainless steel, alloy steel, duplex stainless steel, nickel based alloys, titanium alloys, etc. can be selected according to the properties of the medium and the requirements of the working conditions.
3. Pressure Temperature Rating: The pressure rating of metal sealed ball valves can range from Class 150 to Class 2500, suitable for different working pressures. The temperature range is usually between -46 ℃ and 600 ℃, depending on the temperature resistance of the selected material.
4. Sealing surface treatment: The sealing surface of the ball and valve seat is usually subjected to special hardening treatment, such as spraying nickel based hard alloy, tungsten carbide, chromium carbide or coating nitride and other hard surface materials, to improve wear resistance and abrasion resistance.
5. * * Drive mode * *: Metal sealed ball valves can be equipped with different drive modes such as manual, pneumatic, electric, hydraulic, and pneumatic hydraulic linkage to meet different automation control requirements.
6. * * Additional Features * *: Some metal sealed ball valves are designed with fire-resistant structures, anti-static structures, dual blocking and release functions, as well as stem anti flying design to ensure safety and reliability under extreme working conditions.
7. * * Standard specifications * *: When selecting, corresponding design, structural length, connecting flanges, and testing and inspection standards should be referred to, such as API 6D, API 608, GB/T 12237, GB/T 21385, etc.
8. * * Cooling System * *: For ultra-high temperature applications, metal sealed ball valves may need to be equipped with a cooling system to ensure the stability of the valve under long-term high temperature operation.
Miscellaneous, it is recommended to provide design drawings and detailed parameters for professional review and approval.
