Since the application and the process fluid characteristics are given by the customer are the main factors in selecting a valve type and construction materials, this is considered very important in designs. While clean fluids generally allow a wide range of valves and materials, for dirty fluids and high-risk applications the choice is limited to a few valve types and selected materials.
The Control and Quality Guarantee System:
All input and output equipment of the factory are examined by the control and quality guarantee team of the company and tested and verified by the existing apparatuses. In this respect, some services are outsourced, and thus we appreciate our cooperator laboratories for their partnerships.
Due to the fact that valves have a direct impact on the proper operation of infrastructure and the continuous production process in the industry, quality control and inspection of industrial valves is considered an important issue. Leaks or problems in this sector can disrupt the production or service cycle in these industries or cause accidents. Industrial valves reduce pressure, regulate flow or protect the transmission process. Therefore, it is obvious that the efficiency of sensitive centers such as petrochemicals, refineries, power plants and other industries, whether in terms of output, reliability or proper operation, are directly affected by the performance of valves.
For this reason, different standards for testing and inspection of industrial valves have been introduced by various organizations. These standards are necessary to ensure compliance of valves with technical requirements, process conditions and environmental regulations. These standards also help engineers in the selection process on items such as material, pressure classification and temperature. The following are some of the essential and optional tests in the production of valves:
