CHQ Integration type Electric Actuator

1、Summary
"CHQ" series electric actuator is used for controlling 0°～270° rotation of the valves and other similar products, such as butterfly valve, ball valve, damper, flapper valves, cock valves, etc. It’s widely used in petroleum, chemical, water treatment, shipping, paper making, power plants, heating, building auto-contorl, light industry and other industries. It drives by 380V/220V/110V AC power. Control signal is 4-20mA current signal or 0-10V DC voltage signal, enables move the valve to the desired position, achieving its automation, maximum output torque is up to 4000N·M.
2、Performance Features
2.1 Shell
The shell is made of horniness aluminium alloy, pass through anodic oxidation treatment and polyester powder coating, so it has strong corrosion resistance. Protection grade is IP67, NEMA 4 AND 6, and optional IP68 type and explosion-proof model.
2.2 Motor
Fully enclosed Squirrel-cage motor, small volume, large torque, and small inertia force, F-class insulation rating, built-in thermal protection switch, avoiding damage the electric machinery.
2.3 Manual Structure
The design of handwheel ensure safe, reliable, labor-saving, small volume. When it don’t have electricity, it can be manually operated by clutch handle. When it has electricity, the clutch will reset automatically.
2.4 Indicator
Indicator installs in the center axis, so it can observes the valve position. It adopts convex mirror design, no cumulate water, more convenient to observe.
2.5 Space Heater
It is used for controlling temperature, avoiding internal moisture of electric actuator condensed because of the changing of temperature and weather, keep inner electric device dry.
2.6 Limit Switch
Mechanical, electronic double limit. Mechanical limit screw is adjustable, safe and reliable; electron limit switch is controlled by the cam mechanism, easy adjustment institutions can set the position accurately and conveniently.
2.7 Torque Switch
Providing over loading protect (Except CHQ-005/008/010),avoiding damage the valve and electric actuator.(It’s already setted up before leave the factory, please don’t change the settings)
2.8 Self-locking
Exact worm and worm gear can efficiently transfer large torque, high efficiency, low noise (max. 50 dB), long life, and it has self-locking function to prevent the inversion, transmission part is stable and reliable, no need to add oil.
2.9 Anti-off Bolt
When removed the shell, the bolt would be attached to the shell and didn’t fall off.
2.10 Install
The installation size of the bottom conforms to the international standard ISO5211 / DIN3337, The holes are double square so that it’s easy to fix the linear or 45°corner valves attached square bar, adaptable. It can be installed vertically, and also can be installed level.
2.11 Circuitry
Control circuit conforms to the single-phase or three-phase power supply standard, reasonably compact line layout, wiring terminals can effectively satisfy a variety of additional functional requirements.
