The selection of stainless steel flanged ball valve should be selected according to the user's working conditions. If the selection is wrong, it will affect the use of the product and reduce production efficiency. The following 304 stainless steel flanged ball valve manufacturers will introduce the precautions for the selection of flanged ball valves in detail. !
The selection of stainless steel flanged ball valve should pay attention to the following matters:
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.
2. Selection of valve material
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.
5. Selection of runner form, etc.
The flow channel options of stainless steel flanged ball valve include: straight-through ball valve, three-way ball valve (L-shaped flow channel, T-shaped flow channel), and four-way ball valve.
The above are the precautions for the selection of stainless steel flanged ball valves, I hope to help you.
