    1. Selection of valve seat seal

    Metal hard-sealed ball valve, that is, a ball valve in which the seat sealing surface and the ball sealing surface are metal-to-metal. It is suitable for high temperature, containing solid particles and requiring wear resistance. Soft sealing ball valve, the valve seat is made of PTFE, and the elastic sealing material of para-polyphenylene PPL has good sealing effect and can achieve zero leakage.

    The valve materials of stainless steel flanged ball valves are stainless steel 304, 304L, 316, 316L, etc., and the requirements of different working conditions are different.

    3. Selection of operating temperature and working pressure

    Only by knowing the working conditions of stainless steel flanged ball valves can select normal products. For example, in high temperature conditions, normal temperature ball valves of -40°C to 120°C cannot be selected. In high pressure conditions, high-pressure ball valves of ≥10MPa should be selected.

    4, the choice of structure

    The structural options of stainless steel flanged ball valve include: floating ball valve, fixed ball valve, V-shaped ball valve, eccentric half ball valve, rotary ball valve, etc.
