一、进口角行程电动执行器概述

美国威盾VTON角行程电动执行器用于控制0°～90°旋转的阀门及其他同类产品，如蝶阀、球阀等，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0-10V DC 电压信号为控制信号，可使阀门运动到所需位置，实现其自动化控制，Z大输出扭距达4000N·m。

VTON angle stroke electric actuators are used to control valves and other similar products that rotate from 0 ° to 90 °, such as butterfly valves, ball valves, etc. They can be widely used in various industries such as petroleum, chemical, water treatment, shipbuilding, papermaking, power plants, heating, and light industry. It uses a 380V/220V/110V AC power supply as the driving power, and a 4-20mA current signal or a 0-10V DC voltage signal as the control signal, which can make the valve move to the desired position and achieve automatic control. The Z-axis output torque reaches 4000N · m.

3、手动结构;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，将板手置于板手夹内，方便使用。

4、指示器：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。

5、干燥器：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。

6、密封：密封性好，标准产品防护等级是IP67，并可选IP68防护等级。

7、限位开关：机械，电子双重限位。机械限位螺钉可调，安全可靠；电子限位开关由凸轮机构来控制，简单的调整机构能精确并方便地设定位置，且不受手轮过量的影响。

8、自锁：精密的蜗轮蜗杆机构可高效传输大扭距，效率高，噪音低（zui大50分贝），寿命长；有自锁功能，防止反转，传动部分稳定可靠，无需再加油。

9、防脱螺栓：拆除外壳时，螺栓附在壳体上，不会脱落。

10、安装：底部安装尺寸符合ISO5211/ DIN3337国际标准，孔成双四方形便于带方杆的阀线性或45°转角安装，适应性强。可以垂直安装，也可以水平安装。

11、线路：控制线路符合单相或三相电源标准，线路布置紧凑合理，接线端子可有效满足各种附加功能的要求。

1. Shell: The shell is made of hard aluminum alloy, which has undergone anodizing treatment and polyester powder coating. It has strong corrosion resistance and protection levels of IP67, NEMA 4, and 6. There is also an IP68 type available for selection.

2. Motor: Fully enclosed squirrel cage motor, small size, large torque, low inertia force, insulation grade F, built-in thermal protection switch to prevent damage to the motor.

3. Manual structure; The design of the handle ensures safety, reliability, labor-saving, and small size. When not powered on, manual operation can be performed by pulling the handle. When not in use manually, place the wrench inside the wrench clamp for easy use.

4. Indicator: The indicator is installed on the central axis and can observe the position of the valve. The lens adopts a convex mirror design, which does not accumulate water and is more convenient to observe.

5. Drier: used to control temperature, prevent moisture condensation inside the actuator due to temperature and weather changes, and maintain the dryness of internal electrical components.

6. Sealing: Good sealing performance, standard product protection level is IP67, and IP68 protection level is optional.

7. Limit switch: mechanical and electronic dual limit. The mechanical limit screw is adjustable, safe and reliable; The electronic limit switch is controlled by a cam mechanism, and a simple adjustment mechanism can accurately and conveniently set the position without being affected by excessive handwheels.

8. Self locking: The precision worm gear mechanism can efficiently transmit large torque, with high efficiency, low noise (up to 50 decibels), and long service life; It has a self-locking function to prevent reverse rotation, and the transmission part is stable and reliable without the need for further refueling.

9. Anti detachment bolt: When removing the casing, the bolt is attached to the casing and will not fall off.

10. Installation: The bottom installation dimensions comply with ISO5211/DIN3337 international standards, with double square holes for linear or 45 ° angle installation of valves with square rods, and strong adaptability. It can be installed vertically or horizontally.

11. Circuit: The control circuit meets the single-phase or three-phase power supply standards, the circuit layout is compact and reasonable, and the wiring terminals can effectively meet the requirements of various additional functions.
