在运作效率及节省能源消耗方面，自动控制阀的运用是不可缺少的一环，传统产业界常用的手动阀、气动阀，在安装成本及效率上均不及电动阀。 业内有关人士表示，阀类在工业流程上，大多用来控制各种流体的行进及流量，如水、油、化学液体等，所依据的参数有温度、压力及流量等。而工厂常用的控制阀有减压阀、气动式定温阀、电磁阀定温系统、比例式控制阀定温系统、温度控制阀等几种类型。在选用各类自动阀时，应考虑热机的种类、要求的精度、控制阀的品质、压降、流量及其构造、故障率、厂家信用和售后服务等因素，才能达到经济实用的目的。 就产品本身而言，因电动阀具备装配容易、故障率低以及符合业界自动化需求的优点，是业者较划算的选择。因为使用一般传统气动阀，免不了要有配管、电磁阀及压缩机等才能匹配，而电动阀是以马达驱动，安装简易省事，且电动阀安装配合工厂原有的自控线路即可，可节省其他成本支出。此外，以马达驱动方式开闭较平顺，无瞬间冲力过大的缺点，故障率可大幅降低。 不少人都认为电动阀贵，使用成本高，其实不然，如果以整体计算，传统阀要加上许多配件及管路安装，价格并未占优势，反而要承担较多的保养费用。

The operational efficiency and save energy consumption, the use of automatic control valve is an indispensable part of traditional industry used manual valves, pneumatic valve, the installation cost and efficiency are not and electric valve. The industry concerned that the valves in industrial processes, the most used to control the road and flow of various fluids such as water, oil, chemical liquids, etc. based on the parameters are temperature, pressure and flow. The plant control valves are commonly used in valves, pneumatic-type fixed temperature valve, solenoid valve fixed temperature system, proportional control valve fixed temperature system, several types of temperature control valve. In the selection of various types of automatic valves, they should consider the type of heat engine, the required accuracy, the quality control valves, pressure drop, flow and structure, failure rate, credit and after-sales service manufacturers and other factors, in order to achieve economic and practical purposes. On the product itself, due to electric valve with easy assembly, the failure rate is low, as well as meet the industry's automation needs of the merit of being the industry more cost-effective choice. Since the use of conventional pneumatic valve, will inevitably have a piping, solenoid valve and the compressor in order to match, while the electric valve is a motor-driven, easy to install save trouble, and the installation of electric valve-controlled line with the original plant can be saved in other costs. In addition, motor-driven opening and closing means relatively smooth, non-transient momentum is too large disadvantage of the failure rate can be greatly reduced. Many people think that electric valve expensive, the use of high cost, it is not true, if the overall terms, the traditional valve to add a number of accessories and pipe installation, the price is not dominant, but have to bear more of the maintenance costs.
