Whether Sanitary Valve complies with the standard is a comprehensive assessment involving multiple aspects, mainly including design specifications, material selection, production process, test verification and certification mark. So do you know what are the production processes and test verification methods for industrial-grade valves?

Production process
Process documents: Review process regulations, operating instructions, etc. to confirm that the production process is reasonable and has no obvious defects.
On-site inspection: Visit the factory on site to understand whether the actual production process is in line with the regulations and whether the production equipment is in good condition.

Test verification
Factory inspection: Check whether the valve has undergone routine tests such as pressure test, sealing test, action test, etc. to ensure that all performance indicators meet the standards.
Third-party inspection: Sometimes it is necessary to entrust an independent third-party testing agency to review to increase the objectivity and fairness of the results.

Certification mark
Quality system certification: Confirm whether the manufacturer has quality management system certification such as ISO 9001, indicating the company's quality management capabilities.
Product certification: Whether the valve has obtained professional product certifications such as PED (Pressure Equipment Directive), CE, API, etc., especially for export products, must meet the relevant regulatory requirements of the importing country.
When selecting and applying industrial-grade valves, in addition to considering cost factors, it is also necessary to comprehensively evaluate the quality, performance, and whether the valves can meet specific industrial needs.
