1. General Safety Instructions
Do not open the upper shell when with main power
Check the specification on the nameplate is the same as order specification.
Pls reading the instruction book before using
Pls reset the limit switches when mounting the valve
Do not change the internal wiring
If the power supply is 3 phase, should to check the rotating direction.
2. Summary
"AOX-Q" 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 valve, cock valve etc. It widely applies to petroleum,
chemical, water treatment, shipping, paper making, power plant, heating, light industry and other industries.
Drived by 380V/220V/110VAC power or 24V/110VDC power, inputs 4-20mA or 0-10VDC control signal,
moves valve to the right position, and achieves to automatic control, maximum output torque is 6000N·M.
3. Performance Features
3. 1. Shell--The shell is made of aluminum alloy, with anodic oxidation treatment and polyester powder coating.

3.4. Indicator-- Installs indicator in the center axis and adopts convex mirror design, no cumulate water, more
convenient to observe.
3.5. Space heater-- It is used for controlling temperature to avoid condensing internal of housing and keep dry.
3.6. Limit switch--Mechanical, electronic double limit. Mechanical limit stopper is adjustable, safe and reliable;
electronic limit switch is controlled by cam. Set position accurately and conveniently, and not affected by
excessive handle.
3.7.Torque Switch-- (Except AOX-Q-005/008/010) Providing overload protection to avoid the damage of valve
and electric actuator when jammed by cutting power automatically.
3.8.Self-locking--Accurate worm and worm gear transfer large torque efficiently , high efficiency, low noise
(max. 50 dB), long life, with self-locking, prevent inversion, as stable and reliable transmission parts, no need to
refuel.
3.9. Anti-off bolt—The bolt attaches to the shell and be not off when remove the shell.
3.10.Installation--The installation size meets international standard ISO5211 / DIN3337.
3.11. Circuit--Controlling circuit meets the single-phase or three-phase power supply standard, circuit layout is
reasonable and compact, terminals meet various of additional functional requirements effectively.
3.12 The display of valve position—During the opening or closing movement of actuator, the change of valve
position on LCD is displayed with large numbers.
3.13 Adjust the phase sequence automatically—Intelligent actuator check and test the phase sequence for 3 phase
power supply automatically, users no need to consider about the phase sequence.

8、Installation of Electric Actuators
8.2 Mounting with Valve
8.2.1Turn valve by hand and check the situation, then turn to full-closed position
8.2.2 The drive shaft is removable and solid before leaving factory (picture 9)
(Note:the size of drive shaft can be machined according to user’s requirement in
square or round)
8.2.3 Before mounting,attention to keep correspondence with the rotate direction
between electric actuator and valve
8.2.4 Fix the bracket on valve
8.1 Installation Sites
8.1.1 Notes for interior installation
◎Pls don’t install non-explosion-proof product to the place with explosive gas
◎When installing in the submerged or outdoor, please inform to us in advance
◎Please reserve space for cable repairing , manual operation.
8.1.2 Notes for outdoor installation
In order to avoid rain, direct sunlight and so on, a protective cover or enclosure IP68 is available
◎
Please reserve space for cable repairing , manual operation.
◎
8.1.3 Ambient temperature
◎Ambient temperature at -30℃～+60℃;
◎When Ambient temperature is below zero, need to install space heater.
8.1.4 Fluid temperature
When equipped with valve, the heat of the fluid will transfer to the body, then the body temperature will rise.
◎Standard bracket: when the fluid temperature is below +65℃, with standard bracket or without bracket;
◎ Intermediate temperate bracket: when the fluid temperature is over +65 ℃ , with intermediate temperate
bracket;
◎High-temperature bracket:when the fluid temperature is over +180℃, with high-temperature bracket.
8.2.5Turn electric actuator to full-closed position, fix valve stem and electric actuator drive shaft
Picture 9
by coupling and screws.
8.2.6 Put the electric actuator on bracket, and screw lightly
8.2.7Turn valve by manual to full-closed position and confirm at right situation .
8.2.8Turn electric actuator by manual to confirm non-eccentric, smooth movement, and attention no over travel!
Note: Decrease hysteresis of the coupling as far as possible.
Page 14

8.3 Wire for Power
8.3.1 Remove the metallic plug and insert cables, pls use 3/4” explosion-proof joint in male thread or
explosion-proof flexible tube.
8.3.2 If the joint is mismatch to the actuator, will result in destroying the sealing that can not meet the enclosure
requirement.
8.3.3 Adopt water-proof arrangement when use wire pipe.
8.3.4 Take off shell cover,Press down the metallic dome in the hole of terminal by screwdriver, meanwhile, insert
the leadwire to lateral cavity. And then remove screwdriver.

9. Debug Description
9.1 Adjustment of Mechanical Limit
Loosen the mechanical limit stoppers and locknuts, turn handwheel one circle, one side move the clutch
handle in left until occlude, continue to turn the handwheel until the actuator move to the full-close position. Turn
nuts until touch the fan-shaped gear, then turn two circles in anticlockwise direction, tight the locknuts at lastly. It
is the way to set the full-closed position of actuator , the same way to set full-open position.
Picture 12 Picture 13
Page 15

9.2 Adjustment of Travel Limit(see picture14)
Potentiometer, as output feedback signal , with 3 terminals, ② connect to
the slide arm of potentiometer. ①connect to the terminal whose resistance
decrease between the slide arm when actuator in opening movement.
③ connect to the terminal whose resistance decrease between the slide arm
when actuator when actuator in closing movement.
(Note: The potentiometer resistance should be not subzero、jump phenomenon.)
Turn valve to the full-open position by manual until limit switch move,
Move the electric actuator to the full-closed position by manual. And loosen locknut, turn cam (yellow open, red
close) until touch close limit switch (CLS) , then screw locknut. It’s the way to set the full-closed travel limit
position of electric actuator. Full-open position setting is the same way.
Picture 14
9.3 Adjustment of Potentiometer
measure with a multimeter , adjust the resistance between ② and ① between 35 Ω ～ 60 Ω .If incorrect,
adjusting by turning the drive gear of potentiometer.
9.4 Adjustment of Over torque Protection Device
At nominal working pressure, adjust limit switch cam until touch switch contact roller. If actual torque to
drive valve over the rating torque, cam axle will rotate in clockwise/anticlockwise direction, and drive the cam to
process over torque movement.
9.5 Adjustment of Indicator Plate
Set valve to full-closed position, loosen screws on glass cover, turn the window glass to aline the indicator
direction mark with indicator hand. And then tight screws
(Note:the indicator plate has been set before leaving factory )

★NOTE
★ Note: Debugging description of modulating model, please refer to the specification of the actuator controller
①Check wiring diagram, power supply, control signal.
②Don’t change the internal wiring.
③If the power supply is 3 phase, check the rotating direction.
④Enable the electric actuator lies in a half on/off position by manual, turn on electricity and input open signal.
⑤If the electric actuator runs to the open direction, the wiring is correct.
⑥If the running direction is opposite, change 2 pieces wiring in 3.
11、Maintenance
Lubrication: Because special Mo-based grease is long life and well resistance, so no need to refuel;
Regular operation: Drive and check the device regularly when valve works infrequently.
