一、进口电动全焊接球阀概述

进口电动全焊接球阀（美国威盾VTON），Electric welded ball valve，也叫电动焊接球阀，电动控制球阀，电动焊接式球阀，电动碳钢球阀，是指由电动执行器和全焊接球阀组成，有电动执行器来对全焊接球阀进行开关控制，可实现远程智能化控制。电动全焊接球阀旋转90°即可全关全开，与相同规格的闸阀和截止阀比较。阀体通道和连接管径相等并成一直径，介质几乎可以毫无损失的流过，在石油化工和长输管线等领域有广泛应用。

Electric welded ball valve (VTON), also known as electric welded ball valve, electric control ball valve, electric welded ball valve, electric carbon steel ball valve, refers to a combination of electric actuator and fully welded ball valve, with electric actuator to control the opening and closing of the fully welded ball valve, which can achieve remote intelligent control. The electric fully welded ball valve can be fully closed and fully opened by rotating 90 °, compared with gate valves and globe valves of the same specifications. The valve body channel and connecting pipe have the same diameter and can flow almost without any loss, making it widely used in fields such as petrochemicals and long-distance pipelines.
