一、进口电动球阀概述

进口电动球阀（美国威盾VTON），Electric ball valve，也叫电动开关球阀，电动调节球阀，电动不锈钢球阀，是指由电动执行机构和球阀共同构成阀门，是工业自动化过程控制的一种管道压元件，通常用于管道介质的远程开、关（接通、切断介质）控制，也可配带定位器的智能型电动执行器，对介质进行智能型调节。主要产品有电动法兰球阀，电动对夹球阀，电动焊接球阀，电动丝扣球阀，电动铸钢球阀，电动不锈钢球阀。广泛应用于石油、天然气、医药、食品、水电、核电、电力、给排水、供热、冶金等行业中的空气、蒸汽、水、气体、石油和石化产品、腐蚀性介质。

Electric ball valve (VTON), also known as electric switch ball valve, electric regulating ball valve, or electric stainless steel ball valve, refers to a valve composed of an electric actuator and a ball valve. It is a pipeline pressure component for industrial automation process control, usually used for remote opening and closing (connecting and cutting off the medium) control of pipeline media. It can also be equipped with intelligent electric actuators with locators to intelligently adjust the medium. Our main products include electric flange ball valves, electric clamp ball valves, electric welding ball valves, electric threaded ball valves, electric cast steel ball valves, and electric stainless steel ball valves. Widely used in industries such as oil, natural gas, medicine, food, hydropower, nuclear power, electricity, water supply and drainage, heating, metallurgy, etc., as air, steam, water, gas, petroleum and petrochemical products, and corrosive media.

二、进口电动球阀产品特点

1、电动驱动、法兰连接形式、浮动球直通式，阀座密封面材料有氟塑料 (Q941F)、硬质合金，公称压力 PN16~PN63、公称尺寸 DN15~DN300、适用温度为 -29~450℃，阀体材料有碳素钢、不锈钢和合金钢。

2、调节型电动球阀电动执行机构内置伺服系统，无须另配伺服放大器，输入 4-20mA 信号及 220V AC 电源即可控制运转。和普通电动球阀相比具有结构紧凑，体积小，重量轻，阀座与端面法兰距离近，物料滞留少，密封性能优越等特点。

3、开关型电动球阀采用一体化结构，以单相电源AC220V和直流电源24VDC即可控制运转。
