The difference between a fixed pneumatic ball valve and a floating pneumatic ball valve is that the ball of a floating pneumatic ball valve is floating, that is, only the top is equipped with a stem. Under the action of medium pressure, the ball can produce a certain displacement and press against the sealing ring at the outlet end to ensure that the outlet end is sealed, which is a unilateral forced seal. The structure of this pneumatic ball valve is relatively simple, and the manufacturing cost is low. The process pipeline is widely used in the process of use. Due to the pressure of the medium to compress the seat seal, the design of the floating pneumatic ball valve should focus on the material of the seal ring. If the pressure of the medium is too high, the life of the seat will be affected, and the ball can only have a slight offset, Therefore, the floating pneumatic ball valve is generally applicable to valves with a diameter of DN200 or below and a nominal pressure not exceeding CLASS600Lb (10.0MPa).

Cultivating a strong brand is a question that every stainless steel hose company needs to deal with. In the market environment of modern business types and quality convergence, the market competition is ultimately a brand competition. How to form a strong brand is a question that every stainless steel hose company needs to deal with.
In the modern market environment of "fast fish eat slow fish", the brand of stainless steel hose company cannot be formed by little by little as in the past, but it is necessary to form a good reputation in the industry within three to five years. Therefore, the promotion of brands is particularly important. What is the key of the brand centripetal force of stainless steel hose company? The key lies in the commodity advantages, market advantages and planning advantages of the stainless steel hose company. With strong brand centripetal force, the company has no reason not to prosper.
Although China has now become the manufacturing base of stainless steel hoses in the world, most of our stainless steel hose products are non branded or non branded, which is far from the stainless steel hose products in Germany, South Korea, the United States and other prosperous countries. The key reason is that we lack brand awareness, and even less famous brands with worldwide influence.
The brand demand of the stainless steel hose company itself has been widely promoted through various advertising media and promotion activities, and the merchants need to stop discontinuous promotion. Strong brand centripetal force can enable customers to build up the potential awareness of the brand and blind purchasing habits. For example, when buying threaded stainless steel hose, we first think of Tongfeng hose, which is the result of a long-term brand accumulation that has formed a potential understanding in the hearts of customers, and then the blind purchasing habit.
China's pneumatic butterfly valve industry shows three major trends in the world
As China moves forward in the world from time to time, the countries added from time to time in the world begin to use Chinese pneumatic butterfly valve products, which has affected the development of Chinese pneumatic butterfly valve products to a certain extent. As one of the largest producers of pneumatic butterfly valves in the world, and gradually becoming a major processing and exporting country of pneumatic butterfly valves in the world, China has a broad market and spending potential. With the development of social economy, the stainless steel pneumatic butterfly valve will present a new trend in the new situation.
