Imported intelligent regulating electric actuator
Brand: Weidun V TON
1、 Overview
Imported intelligent regulating electric actuator For control 0 °~270 ° rotating valve and other Similar products, such as butterfly valve 、 globe valve , Wind door , flapper valve, plug valve, shutter valve, etc. It is widely used in petroleum, chemical industry, water treatment, shipping, paper making, power station, heating, building automation, light industry and other industries. It uses AC380V/220V/110V AC power supply as the driving power, 4-20mA current signal or 0-10V DC voltage signal as the control signal, which can make the valve move to the required position to achieve its automatic control, and the larger output torque can reach 5000N · m.
II Imported intelligent regulating electric actuator Performance characteristics
2.1 Housing
The shell is made of hard aluminum alloy, anodized and coated with polyester powder, with strong corrosion resistance and protection grade of IP67, NEMA 4 and 6, and IP68 for selection.
2.2 Motor
Fully enclosed squirrel cage motor is adopted, which has the characteristics of small size, large torque, small inertia force, etc. Insulation class is Class H, built-in overheat protection switch, which can prevent overheating from damaging the motor.
2.3 Manual structure
The design of the handle ensures safety, reliability, labor saving and small size. When the power is off, pull the handle for manual operation. Put the wrench in the wrench holder for easy use when manual operation is not required.
2.4 Indicator
The indicator is mounted on the central shaft to observe the valve position. The lens is designed as a convex mirror, which does not accumulate water and is more convenient for observation.
2.5 Dryer
It is used to control the temperature, prevent moisture condensation in the actuator due to temperature and weather changes, and keep the internal electrical components dry.
2.6 Sealing
Good sealing, standard product protection grade is IP67， IP68 protection grade is optional.
2.7 Limit switch
Mechanical and electronic double limit. The mechanical limit screw is adjustable, safe and reliable; The electronic limit switch is controlled by a cam mechanism. A simple adjustment mechanism can better and conveniently set the position, and is not affected by excessive handwheel.
2.8 Self locking
Accurate worm gear mechanism can transmit large torque, with high efficiency and low noise (large 50 dB), long service life; It has self-locking function to prevent reverse rotation. The transmission part is stable and reliable, and no need to refuel.
2.9 Anti falling bolt
When removing the housing, the bolts are attached to the housing and will not fall off.
2.10 Installation
The bottom installation dimension shall conform to According to ISO5211/DIN3337 international standard, the holes are double and square, which is convenient for linear or 45 ° angle installation of valves with square stem, and has strong adaptability. It can be installed vertically or horizontally.
2.11 Line
The control circuit meets the standard of single-phase or three-phase power supply, the circuit layout is compact and reasonable, and the terminal blocks can effectively meet the requirements of various additional functions.
