All Conditions For Selecting High Temperature Ball Valves Must Be Strictly

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, in the process of use, we 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, so that the valve plate is pressed 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 well, so as not to be a novice in selection and operation.

High-temperature ball valves are widely used in the pipeline industry and are generally recognized and indispensable pipeline components in the industry. Since this type of ball valve is so popular, do you know what are the advantages of this type of ball valve? Let's learn about it together.

1. The material used to make high-temperature ball valves is very powerful. The valve seat is made of polytetrafluoroethylene (PTFE). One of the advantages of this material is that it is very inert and almost does not react with any substance. Moreover, this material has the advantages of low friction coefficient and not easy to age. At the same time, it can show excellent sealing performance in a large temperature range.

Second, the high-temperature ball valve has the lowest flow resistance performance, and can even reach zero resistance. The advantage of this feature is that the pipeline machine valve will not get stuck when working, and it will move very smoothly even without lubricant, thus ensuring the normal use of the valve.

Third, it has a fast opening and closing function. A qualified high-temperature ball valve can achieve an opening and closing time of only 0.05 to 0.1s, which can ensure that the entire pipeline automation system can operate efficiently during operation without leakage and other problems.

Fourth, due to the strong inertia of the rejection, it can be sealed in dual media, and the sealing is very reliable. The high-temperature ball valve is not only inert, but also light in weight. It will not bring great pressure to the pipeline, but can resist the pressure in the pipeline.

The above are some of the advantages of high-temperature ball valves. It is precisely because of these advantages that it has an outstanding position in the industry. If there is a need, you can find a professional and regular manufacturer to purchase.
