电动执行机构 electric actuators

　　电动执行机构可以应用在任何通径的阀门上，并在实践中在任何位置或地方对阀门执行操作。所有装置，无论是直接安装在阀门上，还是安装在地轴架上，都可以在出现电力故障时，进行手动操作。我们具有交流电，也有直流电执行机构，并可以根据所规定操作环境配置恰当的执行机构。电动执行机构可以选择配置限制开关和按钮控制以满足用户的需求。

　　motorized controls may be applied to valves of any size, for operation in practically any position or location. all units, whether installed directly on a valve or on a floor stand, can be manually operated in case of power failure. the units are available for either alternating or direct current and are sized for specified conditions of operation. motor units are available with limit switches and push button controls which can be se-lected to meet customers’ requirements
