What do you need to know to choose a thin-type ball valve? For a thin-type ball valve, use a stud bolt to connect the valve between the two pipe flanges. The flange ball valve has a flange on the valve and bolts the flanges on both ends of the valve. Connected to the pipe flange.

What do you need to know about choosing a thin ball valve?

1. The choice of the thin-type ball valve should first look at the material. The valve with metal seal is generally longer than the valve with elastic seal, but it is difficult to completely seal. Metal seals can accommodate higher operating temperatures, while elastomeric seals have temperature-limited defects.

2. If the ball valve is required to be used as flow control, the main reason is to correctly select the size and type of the valve. The structural principle of the ball valve is especially suitable for making large diameter valves. The thin-type ball valve is widely used not only in the general industries such as petroleum, gas, chemical, water treatment, but also in the cooling water system of a thermal power station.

3. Commonly used thin-type ball valves have two types of clip-on ball valves and flange ball valves. The clip-on ball valve uses a stud bolt to connect the valve between the two pipe flanges. The flange ball valve has a flange on the valve and bolts the flanges on both ends of the valve to the pipe flange.

The thin-type ball valve is suitable for various types of tubes of Class150, PN1.0～2.5MPa, working temperature 29~180°C (sealing ring is reinforced polytetrafluoroethylene) or 29~300°C (sealing ring is para-polyphenylene). On the road, the medium used for cutting or connecting the pipeline is made of different materials, which can be applied to various media such as water, steam, oil, nitric acid, acetic acid, oxidizing medium and urea.
