5 features about fixed ball valve that you have to know

Ball valve is widely used in the field of food, medicine, petroleum, chemical, natural gas, iron and steel, environmental protection, paper and other transfer line medium cutting or circulation. It is the type which has a sphere with the fixed shaft, the fixed shaft are connected together by the two sections with the ball bearing; when it is closed, and together with the function of the medium pressure, the ball will not produce displacement.

Shafts are connected together with the ball, the upper and lower shaft is equipped with rolling bearings or sliding bearings, in order to reduce the open and close when the journal of the frictional force, and to reduce the operating torque. Therefore, the fixed ball valve is suitable for high pressure and large diameter valves. Fixed type ball valve usually are equipped with the activities of the valve seat ring, which can produce a displacement under the action of the pressure of the media, and the seal ring is pressed tightly on the sphere, so as to ensure the sealing performance of the valve.

The features of Fixed ball valve are listed as follows:

1. labor-saving operation: the ball sphere is supported by fluctuation of bearings up and down, which reduces friction and eliminates the inlet pressure promote sphere and sealing seat form the great seal load caused by excessive torque.

2. Reliable sealing property: PTFE unisexual material sealing ring is embedded in stainless steel seat, and the metal seat end is equipped with spring which guarantee enough pre-stressing force of seals, so that the valve continues to ensure good sealing performance under the action of spring, even though the sealing surface wears out during using process.

3. Fire resisting structure: in order to prevent the sudden heat or fire appearance which will lead to PTFE ring burning or large leakage to encourage the fire, there are fire rings set in the place between ball sphere and valve. If the ring burned, the seat ring is rapidly put to the sphere under the force of spring, and forms the metal to metal seal, so as to have a certain degree of sealing effect.

4. Automatic relief function: when the medium abnormal pressure stagnated in the valve mid-plane rises to more than the spring preliminary force, the seat back from sphere to achieve automatic relief effect.

5. Drain line: drainage hole is set both on the upper and lower side of the ball body, which can check whether the valve seat leakage occurs, in the work, when the valve is in fully open or seated, after uninstalling mid-plane pressure, it can directly replace the packing, as well as discharge mid-plane retentate to reduce the pollution of media.

What Adjustment Valve Products Need to Do In The Future?

Like other industries, under the depression of the world economic, valve products are facing to the huge “shuffle”. If enterprises want to survive from bad market environments, they need keep pace with the times to adjust strategy of valve development, operation and research.

The whole industry chain adjustment
As a mechanical device, Butterfly Valves production in the whole industry chain downstream, including steel, sealing materials, and machining industry level of development of technical data will have a major impact. Steel strength, ductility, corrosion resistant high-pressure direct impact on the valve, corrosion resistance; sealing material determines the production level of the applicable media and the valve can withstand the pressure; machining accuracy is affected sealant the valve head and valve seat seal level an important factor.
Enhancement on the degree of specialization
 As a general plumbing Ball Valve, are widely used in many fields, including water utilities, distribution network, petroleum, water treatment, and so many industries. As different industries, different conditions in the project, media, and other aspects of the different sealing conditions, type of valve equipment, materials, pressure rating, etc. are not the same technical requirements, which also caused a valve device for different industries further market segmentation.

How long can Chinese Labor and Raw Material Advantage of Valve Last?

Affected by raw material and labor costs and other factors, in recent years China's valve industry rapidly develop in the international market. Exports and expanding market share has gradually become an important industry base of production and the main sales market. Many valve companies in China, with small size, lack of core competitiveness, difficult to influence in the international market, largely restricted to the healthy development of the valve industry.

At present, China's valve industry is labor-intensive industries, mainly depend on the amount. In order to have long-term development, China's valve industry must adjust and optimize industrial structure. It is necessary to continue to full play to the advantages of traditional valve industry, such as globe valve, ball valve, control valve, but also vigorously develop the knowledge, technology-intensive industries and emerging industries to boost the upgrade of the valve industry. Only in this way can China shorten the gap between the valve industry in China and developed countries as soon as possible.

In recent years, the relief valve market is increasingly competitive. Excessive competition in the market is difficult for enterprises to get healthy and orderly development. Innovation is not only for pursuing high value-added products to get rid of the marginal profit of the relief valve industry, but also can give enterprise new economic growth point. To maintain their survival and development, enterprises are necessary to carry out a series of innovative development of a major leading role and meet the needs of the market high-tech for industrial development to provide strong support. Change the manufacturing into creates.

Companies should adhere to the concept of innovation. In product development and technological innovation aspects, companies positively joint with research institutes, colleges and universities to develop new products, efforts to develop domestic and foreign markets. Thereby these enterprises can overcome the quantitative growth, enhance product quality, and improve the added value of the products, focus on building their own brands to enhance the position of the valve company in China in the global division of labor, improve the ability to resist risks with their own bargaining power, thus enhancing the sustainable development of the valve industry competitiveness.

Clean Energy and Other 3 Factors Will Further Promote the Development of the Valve Industry

Though the global business is going through “the winter”, there are still some favorable factors affecting the development of the valve industry. In China, the favorable aspects are mainly summed up in the following areas:

National industrial policy to promote the development of the valve industry
Chinese "The 11th Five-Year” Outline of the Plan clear point out that we should vigorously develop the equipment manufacturing industry, breakthroughs in core technologies and improve the design of major technical equipment research and development, supporting the core components, the overall level of manufacturing and system integration. Equipment manufacturing industry restructuring and revitalization plan also proposed "basic manufacturing level increased, the general parts basically meet domestic market demand, the key to automated monitoring and control components fill the gaps, special materials to achieve breakthroughs in key areas of planning objectives.

Multinational global procurement and industrial transfer of the valve industry

Procurement activities are the largest cost area in business activities, the quality and efficiency of purchasing largely determines the value and competitiveness of the final product. Global sourcing, companies can achieve procurement cost reduction to enhance the quality of products and suppliers to reduce overall costs while increasing customer satisfaction to gain a global competitive advantage. Today, global sourcing has become an important means of multinational companies to take full advantage of global resources, reduce production costs, enhance core competitiveness, and maximize profits which is an important part of the multinational's global development strategy.

 In recent years, with the industrial upgrading of United States and the European Union and other countries and regions, industrial transfer of the global valve industry trends become apparent. China as a big manufacturing country and emerging market countries, the development of the manufacturing sector has a very high cost advantage which has developed into one of the most important production base in the global valve industry.

Moreover, the technical strength of the domestic valve business is rising, and basically been able to adapt to the requirements of the technical parameters of the global multi-level valve applications. Therefore, more and more multinationals list China as one of the most important countries of global procurement of valve products that creates a lot of business opportunities for domestic strength valve enterprise.

 Clean Energy Has Been Further Development

Under the background of the current global responded to climate change, the development of low-carbon economy has gradually become the consensus of the global economy. Clean energy will be an increasingly important area of ​​the valve industry and applied in butterfly valve, control valve and ball valve. At present, the major global economic bodies and industrialized countries to promote greenhouse gas emissions, develop clean energy to reduce fossil energy consumption through a variety of ways. Nuclear power and natural gas as a worldwide recognized form of clean energy, their future will be in a wider range of applications, and has broad prospects for development. Can be expected that the valves in the field of clean energy will also achieve rapid growth, the valve needs of clean energy will become the new engine of the valve market.

Production processes and material technology continues to mature

After years of development and accumulation, in addition to some special areas, gap between domestic manufacturers and foreign manufacturers in the production process is ever-shrinking. Moreover, with the improvement of the overall technological level of domestic manufacturing, the domestic valve industry in the production of machine tools, production materials and other fields has also achieved a certain amount of technical support. Not only the domestic valve industry has improved in product quality, product variety, the corresponding, but also reduces the cost of the internal valve, contributing to the improvement core competitiveness of the domestic valve enterprises.
