Valve Production Industry is in a Favorable Development Opportunity

Now the machinery industry is developing more and more rapidly, as the industry’s valves are no exception, we all know that the valve industry is an important branch of our general machinery. Its products as a key equipment for fluid control is widely used in petroleum, chemical, metallurgy, electricity, urban construction, environmental protection and other industries. At present, the valve production industry is in a very favorable development opportunity.


The rapid development of the valve industry gradually exposed a lot of problems, and faced with serious challenges, it can be said that opportunities and challenges coexist, achievements and risks with, therefore, actively promote industrial transformation and upgrading, to achieve quality and efficiency breakthrough.

Sanitary valve industry in order to seek greater progress, we must strictly ensure that the valve product safety valve quality, pay attention to the valve process technology improvement and innovation, to produce truly meet customer demand for products. Profoundly analyze the problems and shortcomings in the product, and actively find solutions to the long-term development of the enterprise to prepare.


China’s valve manufacturing industry has been constantly bigger, but the strong road has not yet completed, transformation and upgrading, innovation and excellence is the valve industry bigger and stronger the inevitable choice. Many enterprises have started, entered a comprehensive resource consolidation period, and constantly improve the sector and product categories, give full play to human, material, financial and technological strength and other resources integration advantages, with minimal cost to create the best quality products and services , And constantly promote the adjustment of internal professional structure, to achieve enterprise system and cultural level of improvement, completed by the “can do” to “do” to upgrade and cross.

At present, China’s sanitary ball valve industry are undergoing transformation and upgrading, adjust the product structure, independent innovation, the development of new advantages of intellectual property products, in order to adapt to changes in the market, the supernatural powers, seeking a breakthrough, out of a successful development, In the changing market in the new advantages, and achieved some results. Not only won the market recognition, but also out of the “price war” vicious competition quagmire. Even in the context of the external economic downturn, companies still maintain a strong momentum of steady growth.

Valve Selection And Examples

The valve is a control component in the fluid delivery system, has many functions such as cut-off, regulation, diversion, prevent backflow, regulator, shunt or overflow relief.

Valves are widely used for fluid control systems, ranging from the simplest sanitary shut-off valves to a variety of valves, used in extremely complex control systems, with a wide variety of specifications. Sanitary valves can be used to control the flow fluids such as air, water, steam, corrosive media, mud, oil, liquid metal and radioactive media. Valves are also divided into cast iron valves, cast steel valves, stainless steel valves, chrome molybdenum steel valves, chrome molybdenum vanadium steel valves, duplex steel valves, plastic valves, non-standard custom valves.
Butterfly Valves
Valve selection steps:
1. According to the pressure of the valve, caliber, the media has been the temperature and the temperature can be selected to adapt to the valve model.
2. Know the way the pipe connection and the caliber of the valve can determine the way the valve is connected.
3. The use of the valve If you know and the conditions of the production process, then you can determine the valve drive device.
4. The general diameter of the valve is the diameter of the pipe, but also according to the pipe diameter to calculate the real use of the valve caliber.
5. To determine the sealing surface of the valve to know what the valve is the medium, temperature and pressure values, the maximum use of the valve body temperature must be greater than the medium temperature.
6. Valve nominal pressure to determine the body according to the material, the media working pressure and temperature.
7. Valve characteristics of the media, working pressure and temperature, you can choose the model and sealing surface.
valve fittings
Valve selection example:
Steam pipe working pressure is 13 kg, the temperature is 350 degrees Celsius, caliber is 100, to choose what kind of valve. From the above known conditions, first determine the material of the valve body, because the steam pressure is 13 kg, the temperature is 350 degrees Celsius, you can choose ductile iron or cast steel. However, from the temperature of 350 degrees Celsius to consider, then the ductile iron is more difficult to choose, so for safety reasons, should use cast steel valves. And then from the pressure to analyze, according to cast steel and long-term pressure temperature, the valve should choose 16 kg or 25 kg is appropriate. Next is the choice of sealing surface, to use stainless steel. And given the valve diameter is 100, diameter is relatively small, so the opening and closing time and torque are not large, then select the manual on it. Generally take the steam pipes are made of seamless steel pipe, and seamless steel pipe are used welding, but in order to make the valve easy to install and repair, it is recommended to use the flange connection.

Applications and Market Prospects of Stainless Steel Valve

Stainless steel valves are commonly used in chemical applications such as corrosive media, food, pharmaceuticals, oils, liquid metals and radioactive media. The valve ability is relatively limited by many factors.

Sanitary ball valves
Because of its long life, not rust, green and other advantages, stainless steel valves have many industrial applications, so the procurement of stainless steel valves must be required a variety of stainless steel valve production and factory certificate, you can also use the spectrometer for testing, spectrometer due to high precision, is widely used in the precious metals and stainless steel valve detection. The field of application has also been developed rapidly in recent years, some 304,316 L valves are mainly dependent on the equipment testing.

When the valve material such as sanitary ball valve, gate valve, globe valve and check valve are selected according to the nature of the working medium, the influence of the factors such as the concentration, temperature and heat treatment process of the material on the corrosion resistance must be studied at the same time. Good steel is 316L, 904 or titanium valves.

health grade valves
With the petrochemical industry technology and the continuous development of the petrochemical stainless steel valve, the requirements are getting higher and higher, in addition to continue to improve the quality of conventional valves such as J41W stainless steel globe valve, Z41W stainless steel gate valve, especially for corrosive materials Q41F stainless steel ball valves require an increasing amount, some PTA plants, polyester plants and polyester spinning units for chemical fiber production, to strive to develop corrosion-resistant technology, 316L stainless steel sanitary valves are featured with corrosion-resistant, high strength, light, long life and other excellent features.
The society progress of the industry is increasing, the use of stainless steel valve products industry is also increasing, new industries and new products will also slowly replace the cast iron valves, which for the stainless steel valve industry to bring new opportunities for market development prospects.
