Explosion Proof Electric Actuator

Processing and customized: Yes Brand: TOYI
Type: TCHQ Material: Stainless steel
Connection form: Flange DN: DN15_DN300(mm)
Applicable medium: Water, steam, oil, a variety of highly corrosive chemical media, weak acid medium, ammonia, nitrogen, oxygen, hydrogen, liquefied petroleum gas, air"TCHQ" series electric actuator can be used to control the 90 ° Rotation valves and other similar products such as butterfly valve, ball valve, damper, baffle valve, plug valve and shutter valve with the latest Korean technology, which can be widely applied in various sectors such as petroleum, chemical, water treatment, papermaking, power plants, heating, light industry and so on. It takes 380V/220V/110V AC power as the drive power, 4-20mA current signal or 0-10V DC voltage signal as the control signal, to enable the valve movement to the desired location and achieve auto-control, finally, the maximum output torque up to3000nm.

The main performance characteristics:
1. The shell is made by hard alloy with anodic oxidation and polyester powder coating treatment, which made it has the characteristics of highly anti-corrosion, moreover, it has the ingress protection rating IP67, NEMA4 and 6 and the choices of IP68 and explosion-proof.
2. Motor _ totally enclosed squirrel cage, small size, big torque and small inertia force. To in-set the thermal protection switch that can prevent the motor from damage.
3. Manual structure_ it is safe, reliable, labor-saving and small size. When the power fails, you can operate the clutch handle manually, on the contrary, the clutch will reset automatically.
4. Indicator_ it is installed in the center axis so that you can observe the valve. The lens is designed the same as convex, making it no water logging and observe easily.
5. Dryer_ it is used to control the temperature and prevent the water in the actuator from condensation due to temperature and weather changes, in order to keep the internal electrical components dry.
6. Limit switch_ it is a double limit for machinery and electron. Mechanical limit screw is adjustable, safe and reliable; Electronic limit switch is controlled by the cam mechanism, which can set position accurately and easily by a simple adjustment mechanism without hand wheel excessive influence.
7. Torque switch (TCHQ-010 is excluded)_ it can provide overload protection to prevent the motor from damage. (The manufacturer has set it properly, please do not change it arbitrarily).
8. Self-locking_ the precise double worm gear mechanism can transfer large torque efficiently. It has the features of high efficiency, low noise (maximum of 50 dB), long life, self-locking, anti-reverse, stable and reliable and no need to refuel.
9. Anti-loosing bolt_the bolt will not drop when you remove the outer covering.
10. Installation_ the bottom installation dimensions in line with ISO5211 international standards, and the drive shaft can be removed for processing as requested, either vertical installation or horizontal installation is acceptable.
11. Circuit_the control circuit in line with single or three phase power supply standard, arranging the line compactly and reasonable, the terminals can effectively meet the requirements of a variety of additional features.
12. Worm gear_ it adopted the concave wheel design with the traits of large transmission torque, balance and wear resistance, long service life.
13. PCU board_ compact and reasonable structure, the PCU board is set in the chassis.
