As an industrial automatic control instrument, pneumatic butterfly valve is used more and more widely with the development of industry. When buying pneumatic butterfly valves, many people do not know how to select and identify them, which will cause great trouble. Pneumatic butterfly valve is an industrial product with strong practicability and great extensibility. There are many product models and technical indicators of pneumatic butterfly valve. At the time of purchase, the following three indicators can be identified to obtain pneumatic butterfly valve products with good performance.
Product production qualification of serious enterprises
The first step is to select pneumatic butterfly valve products and identify the production qualification of the enterprise. Pneumatic butterfly valve is a national special equipment, and the relevant technical specifications and production qualification of the enterprise are strictly controlled by the state. Only by obtaining the relevant qualification certificate issued by the state, can we fundamentally protect our legitimate rights and interests, and avoid purchasing fake and substandard products that do not meet industrial requirements.
Enterprises engaged in manufacturing pneumatic butterfly valves must have the following production qualifications: explosion-proof product certificate, special equipment manufacturing license, national industrial production license, and the U.S UL Certification, EU CE Certification ISO9001 National quality management system certification. The first step of selecting correctly is to distinguish the small workshops that do not meet the production qualification, so as to ensure the product quality.
Review the R&D strength of the company
Pneumatic butterfly valve belongs to industrial automation precision instrument, and the use and working environment of the product are relatively complex. Naturally, an excellent product research and development team must be diligent and keep improving in product research and design.
The core of modern enterprise competitiveness is the enterprise's self-help R&D and innovation ability. The development of science and technology makes the product renewal cycle shorter and shorter, and the product quality more and more stable. The enterprise's R&D strength considers the enterprise's pursuit of products. The technology of pneumatic butterfly valve equipment is constantly updated. With more and more extensive industrial application, pneumatic butterfly valve products also have higher requirements on precision, applicability, reliability and service life. According to the research and development strength of the enterprise, the manufacturer of pneumatic butterfly valve with strong research and development strength is more secure in terms of products.
See the application of products in large projects
so-called "Practice leads to true knowledge". The products produced by enterprises should be able to withstand the test of the market and play a role in large-scale industrial projects. Therefore, when selecting products, we can learn from the side which large-scale industrial projects the enterprise's products have done.
Pneumatic butterfly valves are widely used in food machinery, petrochemical industry, biopharmaceuticals, military industry and national defense, etc. It can be seen that pneumatic butterfly valves are important in industrial production. Therefore, if the products of the pneumatic butterfly valve manufacturer are used in many large projects, it must confirm the stability and reliability of the products and can withstand the actual inspection.
At present, there are many manufacturers of pneumatic butterfly valves, ranging from national high-tech enterprises to small workshops. Among many manufacturers, Juliang Valve Industry Group is worth recommending.
