Making brand is a solid choice for valve company

"OEM narrower, must have the independent brand, but the transformation of the road is not easy." This is the recently held fifteenth session of Haijiao Hui channel brand culture forum, and said a foreign trade enterprises responsible person said to remember, human fight, fight cost "sweat economy" has failed, brand is the best choice.
Responsible for the foreign trade enterprise troubles caused by many foreign trade enterprises resonance, these enterprises generally face two difficulties: one is the appreciation of the renminbi, raw material prices, labor shortage caused by rising costs; two is from the surrounding low cost countries manufacturer's competition, these problems also plagued China AWWA C508 Water Check Valves company..
Shanghai Export Commodities Enterprise Association Feng Zhengzhou said: "the low price competition has not sustainable, foreign trade enterprises should walk out of predicament, to transfer from the sales price to the value of sales of product design, product function, brand culture, to completely reverse the heavy production, light brand marketing exchange ideas."
Overall, at present foreign trade enterprise transformation has three directions: first is the development of emerging markets in the Middle East, Latin America, Africa, Southeast Asia and so on; the second way is to create a foreign brand; three is to enter the domestic market, the three point is the future of China's Valve Factory go in the direction of.
"We try to create their own brands into the international market, but because the market marketing means and the lack of funding, foreign customers do not recognize us, so many enterprises always dare not to take a step. A company official said, "but even so, the enterprise must have its own brand, the direction of don't be afraid of the distance." Shanghai Ming Bao valve that it is worth China learning from the valve company, or that sentence future valve industry will be the enterprise brand competition.

The operation process of prior period opening pressure of safety valve

1.Flanged Safety Valves before delivery, should be by Taiwan to adjust its opening pressure to the user's setting. If users spring pressure level, according to the general should be adjusted by the lower limit of pressure level of the factory.
2. User before install the valve onto the protected equipment or before installing, adjustment must be installed on site, to ensure that the relief valve setting pressure value conforms to the requirements.
3. Within the scope of work indicated on the nameplate of the spring pressure level, by turning adjustment screw to change amount of spring compression, the opening pressure can be regulated. (4) before the rotation adjustment screw, valve inlet pressure should be brought down to the opening pressure is less than 90%, in order to prevent the rotation adjustment screw when the disc is driven to rotate, so that damage the sealing surface.
4. To guarantee the accuracy of the opening pressure value, should make adjustment when the medium conditions, such as type, temperature as close as possible to the actual operating conditions. Medium type change, especially when the accumulated state of the medium not (e.g., from a liquid into a gas phase) at the same time, the opening pressure is often change. Work at higher temperatures, the opening pressure is generally reduced. In room temperature adjustment and when used in high temperature, room temperature should be slightly higher than the setting pressure value of opening pressure value of the request. High to what extent and valves are relationship, structure and material selection should be according to manufacturer's instructions.
5. Regular safety valve used in fixed additional back-pressure occasions, when adjust the opening pressure after inspection (back pressure to atmospheric pressure) at this time, the setting value shall be the requirements of opening pressure value minus the superimposed back pressure value.

Special check valves in the passive core-flooding system

 Through an article titled “Resolve Koodankulam Issues” in TNIE (April 19, 2013), I had brought out certain serious safety issues emanating from the supply of substandard components and equipment imported and installed in the Russian VVER 1000 MWe Units 1 and 2 at the Koodankulam Nuclear Power Project (KKNP) under construction in Tamil Nadu, India. I had also pointed out that a major Russian government company, ZiO-Podolsk, might have supplied components and equipment of poor quality to KKNP, possibly impacting the reliability and safety of the two nuclear reactors there.
NPCIL, in an additional clarification released on April 20, admitted that “four valves in the passive core-flooding system, though initially tested in factory premises under simulated conditions, showed variations from expected performance during integrated testing at the KKNP site.” This underplays the gravity of the entire situation. These four are “special check valves”, and they are crucial to the long-term core-cooling under severe accident conditions, including a total loss of electric power. It is a fact that no adequate testing of these valves was done in Russia. How could this happen in spite of the highly-lauded, multi-tier quality control programme under which NPCIL claims that an inspection team of theirs, stationed in the Russian factory, has witnessed and signed off on this testing?

Plumbing valve companies attempt to expand the domestic market

Yuhuan plumbing valve industry in yuhuan county government's vigorously support, after years of development, now both product quality and sales has made great progress and have different pattern, believe in the near future yuhuan plumbing valve products will be a household name in China.
First contact yuhuan plumbing valve products of Beijing construction engineering material construction metal structure association branch deputy secretary-general HuoQingMin, in addition to carefully observe the showroom each product appearance, also inquired about the price. "Looked really good, I think in the future in addition to my personal will to purchase, I would actively recommend to the people around." HuoQingMin said.
According to understand, my county in addition to yuhuan plumbing sanitary ware famous brand exhibition hall was established in Beijing, is still in active preparation China valve city marketing center, and will be opened around end of September this year of linyi in shandong province. At the same time, our county in the future will also be other urban centres across the country gradually establish a plumbing valve unified marketing center.
ZhangYong, said the county government hope that through this a series of measures, prompted as a capital of China Forged Steel Valves, faucet production base in China yuhuan onto a new stage, and promote the transformation and upgrading of our county plumbing valve industry sustainable development, and health.

Globe valves different from ball valves are used for applications requiring throttling

A globe valve different from ball valve is a type of valve used for regulating flow in a pipeline, consisting of a movable disk-type element and a stationary ring seat in a generally spherical body.

Although globe valves in the past had the spherical bodies which gave them their name, many modern globe valves do not have much of a spherical shape. However, the term globe valve is still often used for valves that have such an internal mechanism. In plumbing, valves with such a mechanism are also often called stop valves since they don't have the global appearance, but the term stop valve may refer to valves which are used to stop flow even when they have other mechanisms or designs.

Globe valves are used for applications requiring throttling and frequent operation. For example, globe valves or valves with a similar mechanism may be used as sampling valves, which are normally shut except when liquid samples are being taken. Since the baffle restricts flow, they're not recommended where full, unobstructed flow is required.

Compounds of natural have been used for decades for gate valves and flange gaskets

There are numerous potential sources of contamination in potable water systems, not least of which is contact with the components comprising these systems. On its journey from the source to the tap, water typically passes through miles of pipe and various mechanical devices such as pumps, meters, and valves, all of which require seals.
Because of their resilient properties, elastomers account for a large portion of these materials. Compounds of natural , styrene butadiene , and acrylonitrile butadiene rubbers and Chloroprene (Neoprene) have been used for decades for pipe seals, gate valves, flange gaskets and O-rings.
Ethylene propylene diene rubber , with its superior hydrolytic stability and resistance to chloramines, is becoming more widely used in these applications. Even fluoroelastomers are being used in gaskets for CPVC piping, where leaching of plasticizers from other elastomers can compromise the piping.
Rubber-bound fiber sheet finds application in a variety of flange gaskets where, because of limitations on size or gasket stress, homogenous elastomers cannot be used. Polytetrafluoroethylene based materials are used in applications where chemical resistance or high levels of purity are required. Glass fiber reinforced epoxy is widely used in gaskets where mating flanges must be electrically isolated .

Valve casting industry should attach much importance to the development trend in the diversification

Although valve casting products have broad prospects, the per-capita consumption level of valve casting products in China is not high in the world at present. The valve casting industry belongs to rising sun industry, which has become the fundamental material industry that nips and necks with steel, cement, timber and other industries. Domestic far-sighted entrepreneurs, investors who invest in the safety valve casting industry believe that they must be smooth in days and get right time.

But it is highly significant that the threshold of investment in the valve casting industry has been rising. As the relevant industry has presented the development trend in the diversification and depth, the status of the valve casting products has gradually expanded from the commodity to a broader industrial area; high-tech field puts forward a higher requirements for valve products; at the same time, the environmental protection treatment, utilization and recovery of all kinds of discarded valves is becoming more difficult.

In the market environment of fierce competition, the pump valve manufacturing enterprises unceasingly change the development ideas of enterprises, comply with the development of the market and change marketing mode for pursuing the enterprise survival. Many enterprises will put their sights into the internet. The pump valve industry can either select to cooperate with the large-scope e-commerce company or choose to collaborate with network marketing outsourcing, to constantly strengthen the network marketing and stride forward the real sense of the e-commercial road.

Valve industry is a huge industry group which plays an important role in the national economic construction. According to the incomplete statistics from the pump valve transaction network, national pump valve manufacturing enterprises is not less than 200 thousand, the personnel engaged in the commerce of the pump valve is more than one million. It is reported that at present many pump valve manufacturing throughout the country have joined the electronic commerce circle. But relatively speaking, there is a certain difficulty in business plan that the enterprise is completely independent to implement; and there are bottlenecks existing in the manpower, resources and technology.

Increase more support to push forward the high-end development of the valve industry

The development momentum of China valve industry is fierce, but under the excellent background of industry situation, there are some problems worth worrying about, especially domestic valve enterprises focus on low-level, small-scale, family-owned enterprises, which is a big constraints and bottlenecks for the future development of China valve industry.

Along with the country accelerating the development of the equipment manufacturing industry policy, the priority will be further given to the development of the general basic manufacturing industry. China is faced with the arrival of the industrial era. The petrochemical industry, power sector, metallurgic industry, chemical industry and urban construction will increase demand on the valve products.

The competition of the valve market is heating up. Some of the ordinary valve markets have tended to saturate and presented excess supply, which makes the development of small and medium enterprises increasingly difficult. However, even products with high technological content, there is also a fierce competition in the international market. Still rely on imports in the field of the High Pressure Butterfly Valves, which the future China valve needs to break through so as to effectively push forward the development of China valve industry.

We have faith in the fact that in the wake of the pace accelerated by continuous of the valve industry restructuring, the competition between the valve industries in the future will be the competition between the quality safety and product brand of valve. Products develop towards high technology, high parameter, resistant to corrosion and long life. The domestic valve industry also will present a better development prospect under the vast demand conditions

The development trend and prospect of 2013 valve instruments

In 2013, due to China keep the good investment environment and infrastructure investment constantly, instruments and meters in China butterfly valves industry sustained growth will usher in new opportunities for development. Continuous self innovation, achievement the leading technology, all kinds of products are too many things to see, presents a picture of a booming development prospects. Just because of such technology, makes the Industrial Butterfly Valve Manufacturer instrument and meter industry can remain positive momentum.
Instruments and meters will be an unprecedented big development, the demand for instrumentation products in domestic market will remain at around 62 million sets. Power sector needs more than 5000 sets of other departments needs millions of sets. Shenzhen valve products demand also changes in the structure, proportion of electronic watt-hour meter of watt-hour meter products will gradually increase, from the "11th five-year plan" at the beginning of 5 million to the end of the forecast of up to 15 million units. Meter installation, portable electric meter, digital instrument technology will also increase, the level of products constantly upgrading. So, despite the product total annual demand in recent years won't have too big change, but sales have increasing trend, expected annual growth rate of 11%.
The valve 2013 instrument of development a long way to go, should need continuous efforts, need continuous in domestic product reliability, applicability and performance.
