产品概述
精小型阀门电动执行器用于控制0°~270°旋转的阀门及其他同类产品,如蝶阀、球阀、风门、挡板阀、旋塞阀百叶阀等。可以广泛应用于石油、化工、水处理、船舶、造纸、电站、供热、轻工等各行业中。它以380V/220V/110V交流电源为驱动电源，以4-20mA电流信号或0-10VDC电压信号为控制信号，可使阀门运动到所需位置，实现共其自动化控制，最大输出扭距达4000N·m.
Electric actuator is used for control 0° ~ 270" rotation of the valves and other similar productsSuch as butterfly valve, ball valve,damper, flapper valves,cock etc.lt"'s widely used in petroleum ,chemicalwater treatment, shipping, paper, making ,power paints ,heating,light industry and other industries,ltdrives by 380V1220V/110VAC power,Control signal is 4-20mA current signal or0-10vDC voltage signalenables move the valve to the desired position ,achieving its automation,maximum output,torque is upto 4000N.m..
精小型阀门电动执行器性能特点Perrormance Features
1 、壳体Shell
壳体为硬质铝合金,经阳极氧化处理和聚酯粉未涂层,耐腐蚀性强,防护等级为IP67.NEMA4和6,并有IP68型供选择.
The Shell is made ofhorniness aluminum alloy, pass through anodic oxidation treatment andpolyester powder coating ,so it has strong corrosion resistance.Protection grade is IP67, NEMA4 and6.and optionallP68 type.
2 、电机Electric Machinery
全封闭式鼠笼式电机，体积小，扭距大，惯性力小，绝缘等级为F级，内置热保护开关，可防止损坏电机.
Fully enclosed squirrel-cage electric Machinery, small volume,large torque,and small inertiaforce, F-class,insulation rating ,inside hot protection switch,avoid damaging the electric machinery.
3、手动结构ManualStructure
手柄的设计保证安全可靠、省力、体积小，不通电时，扳动手柄可进行手动操作，不用手动时，将扳手置于扳手夹内，方便使用。
The design of handle ensure safe, reliable, labor-saving, small volume,Whenit don't have electricityit can be manually, operated by handle When you don't operate by manus,you can put the wrench in thewrench folder.then you can easy to use it.
4、指示器Indicator指示器安装在中心轴上,可以观察阀门位置,透镜采用凸出镜设计，不积水，观察更方便。Indicator installs in the center axis, so it can observes the valve position, it adopts convex mirrordesign.nocumulate water, more convenient to observe.
5 、干燥器Space Heater
用来控制温度,防止由于温度和天气变化导致执行器内部水分凝结,保持内部电气元件的干燥It is Used for control temperature, avoiding internal moistuer of electric actuator condensedbecause of the changing changing oftemperature and weather,keep inner electricdevice dry,
6 、密封Sealing
密封性好,标准产品防护等级是IP67.并可选IP68防护等级.
Good sealing, performance,and the protection class ofstandard product is IP67, and optional lp68protection grade.
