With the rapid development of industrial technology, China’s valves are more and more widely used in engineering, and their performance and quality directly affect the safety, reliability and economy of the entire project. Therefore, the selection of China’s valves has become a concern for many enterprises. This article will be from the Chinese valve selection standards, methods and other aspects of in-depth discussion, to help you better choose their own engineering needs of the Chinese valve.
First, China’s valve selection standards
1. Chinese valve types and specifications
The type and specifications of Chinese valves are the primary criteria for purchasing Chinese valves. The main types of Chinese valves are ball valves, globe valves, gate valves, butterfly valves, regulating valves, etc. Different types of Chinese valves have different performance characteristics. Therefore, when purchasing Chinese valves, we should choose the right type of Chinese valves according to the actual needs of the project.
In addition, the specifications of China’s valves mainly include China’s valve caliber, pressure rating, temperature range, etc. When purchasing Chinese valves, it is necessary to ensure that the selected specifications match the engineering needs to ensure the normal operation of Chinese valves.
2. Chinese valve material
The material of China’s valves directly affects the corrosion resistance, wear resistance, sealing and other properties of China’s valves. At present, the commonly used Chinese valve materials are cast iron, carbon steel, stainless steel, alloy steel and so on. In the purchase of Chinese valves, we should choose the appropriate Chinese valve material according to the environment and media characteristics of the project.
3. Chinese valve performance
The performance of Chinese valves mainly includes sealing performance, flow performance, adjustment performance and so on. When purchasing Chinese valves, we should focus on the performance indicators of Chinese valves to ensure that the selected Chinese valves can meet the engineering needs.
4. Chinese valve manufacturing process
The manufacturing process of Chinese valves directly affects the quality, service life and reliability of Chinese valves. When purchasing Chinese valves, we should pay attention to the manufacturing process of Chinese valves and choose Chinese valves with excellent manufacturing process.
Second, China’s valve selection method
1. Refer to industry standards
When purchasing Chinese valves, you can refer to the relevant national and industry standards, such as GB/T 12220-2015 “China valve type preparation method”, GB/T 12221-2017 “China Valve structure Length” and so on. These standards have clear provisions on the type, specification, material, performance and other aspects of Chinese valves, which can be used as a reference basis for the purchase of Chinese valves.
2. Understand the manufacturer’s reputation and product quality
In the purchase of Chinese valves, to choose a good reputation and product quality manufacturers. You can understand the manufacturer’s reputation and product quality through network inquiries, peer consultation and other ways to ensure that the purchase of high-quality Chinese valves.
3. Compare product price and performance
When purchasing Chinese valves, we should compare the price and performance of different manufacturers and different models of Chinese valves, and choose cost-effective Chinese valves. In comparison, we should not only pay attention to the price of the product, but also pay attention to the indicators of the material, performance and manufacturing process of China’s valves.
4. Pay attention to after-sales service
In the purchase of Chinese valves, we should pay attention to the manufacturer’s after-sales service. As engineering equipment, Chinese valves may fail during use and need to be repaired in time. Therefore, when purchasing Chinese valves, it is necessary to choose a manufacturer with good after-sales service to ensure the normal operation of Chinese valves during use.
Sum up
The purchase of Chinese valves involves many aspects, including Chinese valve types and specifications, materials, performance, manufacturing processes and so on. In the purchase of Chinese valves, according to the engineering needs, comprehensive consideration of these factors, choose the right Chinese valves. At the same time, in the purchase of Chinese valves, but also pay attention to the reputation of the manufacturer and product quality, compared product price and performance, and pay attention to after-sales service. Only in this way can we buy high-quality Chinese valves to ensure the safety, reliability and economy of the project.
