The quality standards and certification requirements for all types of valve products vary by industry and application. In general, valve products need to meet the relevant national and international standards, such as ISO (International Organization for Standardization), API (American Petroleum Institute), ASME (American Society of Mechanical Engineers), CE (European Conformity Certification) and local standards in various countries. These standards cover valve design, materials, manufacturing processes, performance testing, quality management and safety. Specific indicators include flow characteristics, pressure rating, temperature adaptation range, corrosion resistance and tightness.

Choosing valve products that meet high standards is an important part of ensuring industrial safety and production efficiency. First of all, choose brands and products with industry certification, different industries have specific certification standards, understand and confirm the industry standards of the required valves, you can choose products that meet these standards. Second, to look at the material and process of the valve, high-quality valves are usually made of durable alloys, stainless steel or high-strength plastics, and undergo rigorous testing and quality control. At the same time, choose manufacturers and suppliers with a good reputation, they usually provide technical documentation and test reports of the product to ensure that the product meets the relevant standards. In addition, considering the actual application environment, such as temperature, pressure and medium type, it is also very important to choose a valve that can meet these requirements.

The accidents that can result from substandard valves can be quite serious, with potential risks including leakage, explosion or fire, equipment damage, and loss of control. Poor quality valves are often defective in sealing performance, prone to leakage, resulting in material loss or environmental pollution, which will not only lead to production losses, but also may bring safety threats to workers and the environment. In liquid or gas delivery systems, valves that cannot withstand high temperature and pressure may lead to sudden system failure, resulting in an explosion or fire. Unqualified valves in the long-term use of the process may be due to lack of durability caused by internal wear, stagnation, etc., which affects the operation of the entire system, resulting in equipment failure and shutdown, resulting in economic losses. In critical process control, poor quality valves can lead to fluid flow instability, adversely affecting the production process, resulting in degraded production quality or damage to equipment.

Therefore, when selecting valves, it is important to ensure that their product quality meets industry standards. High standard valves can not only provide better security for the operating system, but also improve the reliability and stability of the system in long-term use.
