Inspection and measurement disciplines are embedded throughout our processes



We create a detailed valve inspect report based on the specific requirements. The best overall of a valve achievement, carefully combining the appearance, technology, and budget. Reliability and durability are our goals.

Being part of the process from beginning to end is very fulfilling and makes quality control exciting, and meaningful. The AMO, a valve manufacturer based in China, practices quality management framework concentrated on overall product quality control, including valves,valve cores,valve repair tools. It is an advanced management approach that works across a company, involving all departments and workers, and extending to include both valve manufacturer and customers. This is the reason why, the development of our valve includes not only the material resources and fundamental equipment, but also the control of practical processes, and documentation to accomplish your requirements.

From material sourcing to final outgoing inspection, quality control is carefully monitored. At AMO facility, in-process checkup is an overall effort performed at each stage of valve manufacturing. A well-equipped workshop in China is here for conducting special tests according to international standards or specifications. Thereby, a high level of customer satisfaction cannot only be achieved, but also be extended. There are 3 stages in the AMO quality control system.

Incoming Inspection


Raw material specifications and inspection program with precisely defined parameters and approved criteria are golden rule for all brass & rubber raw materials going as valve components.
The main checking methods are shown as below:
•Spec testing
•Hardness testing
•Composition testing


Process Quality Control


Process quality control is carried out with all major machines, by employing control documentation which is exercised at each and every process. The regular inspection practices are shown as below:
•Structure testing
•Thread testing
•Pull force testing
•Hardness testing
•Viscosity testing
•Aging testing
•100% Air-tightness testing
AMO 100% Air-tightness testing
AMO 100% Air-tightness testing
AMO Pull force testing

Finished Valve Testing


Valves are subjected to final tests for verifying compliance with international TUV standard as well as customer’s specific requirements. Customers will have our test certificates for reassuring them of the product quality.
