    Valve standard number and name

    2014-08-13 Number of attention:

    Valve manufacturing enterprises have an implementation standard, implementation standards include national standards and enterprise standards, national standards are unified, enterprise standards can be based on the enterprise itself to do the specification. The main function of the implementation standards of commodities is to eliminate counterfeit and inferior products, ensure the quality of commodities, and have a supervisory role.


    Valve manufacturer belongs to the machinery manufacturing industry, such as gate valves, ball valves, butterfly valves and other valves have occupied an important position in the national economic construction. The following is the introduction of odd high valve to introduce the implementation criteria of the valve.
