Comparison And Distinction Between High Temperature Ball Valve And High Temperature Stop Valve

The application range of 2PC Flanged Ball Valve is very wide. For example, it will be used in some fields such as chemical industry, metallurgy, hydropower, etc., but there are certain matters that need to be paid attention to during use. Let me introduce them to you below.

1. Because there are multiple layers of soft and hard stacked sealing rings fixed on the valve plate of the high-temperature ball valve, when the slide plate is in a normally open state, the medium will form a flushing force on the sealing surface of the high-temperature ball valve, and the soft sealing belt in the metal interlayer will directly affect the sealing after being flushed. Therefore, during use, you must pay attention to the sealing performance.

2. When making a high-temperature ball valve, the diameter should be greater than dn 200. If the overall structure of the valve plate is too thick, there will be a great flow obstruction, that is, the diameter is limited by structural conditions.

3. In fact, the sealing performance between the sealing surface of the valve plate of the high-temperature ball valve and the valve seat mainly depends on the torque of the transmission device, which makes the valve plate press against the valve seat. If it is in a positive state, the higher the medium pressure, the tighter the sealing extrusion will be. Therefore, when the medium flows back, as the medium pressure continues to increase, when the unit positive pressure between the valve plate and the valve seat is less than the medium pressure, the seal of the high-temperature ball valve will begin to leak.

The above are the precautions for high-temperature ball valves. In the process of daily use, you must pay more attention. In order to buy higher quality and avoid wrong operation during use, the editor recommends that every consumer should understand the relevant high-temperature ball valve knowledge and know it in mind, so as not to be a novice in selection and operation.

The application range of high-temperature stop valves is also very wide. For example, it is used in some industries such as chemical, pharmaceutical, water treatment, and electronic industries. The main function is in the pipeline, mainly for cutting off. So, what are the advantages of high-temperature stop valves? Why is it so widely used?

1. Good sealing and long service life

When opening and closing, the friction of the sealing surface is very small, so it has good wear resistance. In addition, its sealing performance is also very good, and the friction between the sealing surfaces is very small, so its service life is very long.

2. Good process and easy maintenance

The opening height is relatively small, and generally there is only one sealing surface, with good manufacturing process, and later maintenance is also very simple. In addition, the structure of the high-temperature stop valve is very simple, which is very convenient in both manufacturing and maintenance. At the same time, the working stroke is relatively small, and the opening and closing time is relatively short.

3. Wide range of applications

The application range is very wide, such as oil and gas, power plants, mechanical equipment and other fields can see the figure of high-temperature stop valve. Not only has the performance of high temperature and high pressure, but also its sealing is very tight and its service life is very long. However, the opening and closing torque is large, so its structural length is very long, which leads to a large fluid resistance loss, which also limits the scope of use to a certain extent.

In short, the application range of high-temperature stop valves is still very wide. With the above advantages, customers should choose those produced by regular manufacturers when choosing high-temperature stop valves. After all, the quality and after-sales of such large manufacturers will be more guaranteed.
