What are the specific systems of the valve electric device

阀门电动执行器标准体系是指将全行业面对市场需求和针对行业企业产品生产及新产品开发中,有利于制造与使用双方所需全部标准的综合,使各项标准之间在适用对象、范围和内容等方面相互关联、相互协调、相互制约。标准体系是合理覆盖全行业生产和技术的科学有机体,同时也要考虑到与各相关领域的衔接与配合。

The valve electric device standard system refers to when the whole industry facing the demand of the market, for the production of enterprises and the development of new products in the industry, in this way can benefit all the standards required for the manufacture and use of both parties. To interrelate, coordinate and restrict each other in the applicable objects, scope and content. The standard system is a scientific organism that reasonably covers the entire industry's production and technology. It also needs to consider the convergence and cooperation with related fields.
