1. Overview

Q series electric valve actuator is suitable for small and medium diameter butterfly valves, ball valves and other valves with 90° rotation and other similar equipment. As a stable and reliable angle stroke actuator, it can be applied to different control systems and different working environments. The integrated design of transmission mechanism makes the product with smaller volume and simple appearance. Safe and reliable manual design, fully automatic manual/electrical switching without switching handle. Good protection level can meet the needs of a variety of designs: explosion-proof, integral switching type, integral regulating type.

2. Technical Parameters-Q40 type valve electric actuator

1. Power supply: three-phase AC380V/50Hz for motor, two-phase AC220V/50Hz (ExdⅡBT4) for control. Optional power supply: AC220~660V, 50, 60Hz (to be specified when ordering)

2. Ambient Temperature：-20℃~+60℃，Optional Temperature：-40℃~+70℃

3. Relative humidity: not more than 95% (at 25℃)

4. Operating environment: ordinary type is used in places without flammable, explosive and strong corrosive media; explosion-proof type is used in ⅡA,IIB class T1-T4 group of explosive gas mixtures

5. Protection level: IP65/67 (special order IP68)

6. Motor for the work system; rated running time of 10 minutes. class F insulation.

7. Anti-corrosion coating: high temperature baking paint

3. Installation and disassembly

Allow the valve electric actuator installed in any position, but must pay attention to the motor as far as possible in a horizontal position, the electrical box cover is horizontal or vertical upward state for the recommended installation, which is conducive to lubrication, commissioning, maintenance and manual operation.

4. Wiring precautions-Q40 type valve electric actuator

Allow the valve electric actuator to be installed in any position, but must pay attention to the motor as far as possible in a horizontal position, the electrical box key corresponds to, if it is not consistent immediately press the stop button, cut off the three-phase power supply, switch to any two-phase three-phase power supply.

5. Adjustment of travel control mechanism

1. Turn the handwheel to make the valve “fully closed”, loosen the screw on the output shaft, turn clockwise to turn off the cam, so that it is just to press the off to the microswitch, and then tighten the screw.

2. Turn the hand wheel to make the valve “fully open”, loosen the screw on the output shaft, turn the open cam counterclockwise so that it just presses the open micro switch, and then tighten the screw.

3. Manually or electrically open or close the valve, check whether the valve open or close to meet the requirements, if not, according to the above steps to fine-tune, until it meets the requirements.

6. Mechanical limiting mechanism adjustment-Q40 type valve electric actuator

The purpose of the adjustment is to limit the valve switching parts (disc, ball, etc.) in its working stroke (generally 90 °), so that it can not rotate at will.
1. So that the valve is in the “full off” position, screws and limit the position of the body as shown in the figure, turn into the off position of the mechanical limit screws to the top of the screws to contact the limit of the body, and then return the screws to 1 ~ 2 turns, and then tighten the lock nut.
2. So that the valve is in the “fully open” position, according to the above method to adjust the open position of the mechanical limit screws.

7. Torque control mechanism adjustment

The torque control mechanism has been adjusted to the ^maximum output torque on the product nameplate at the factory, and the user generally does not make adjustments.

8. Troubleshooting-Q40 type valve electric actuator

serial number	malfunctions	rationale	Methods of elimination
1	The motor doesn’t work.	1. Power cord disconnection 2、Control line failure 3、Stroke or torque mechanism failure	1、Check the power cord 2. Troubleshooting lines 3. Troubleshooting travel or torque faults
2	Output shaft orientation not in accordance with regulations	Reverse power cord sequence	Swap any two power cords
3	Motor overheating	1. Continuous working time is too long 2、Motor and actuator mismatch 3. Lack of phase	1、Stop running to cool the motor 2. Checking the supporting situation 3、Check the power cord
4	Motor stops during operation	1、Torque control action 2. Valve failure	1、Increase the set torque 2、Check the valve
5	Motor won’t stop or light won’t come on when in place	1. Failure of travel or torque mechanism 2、Improperly adjusted travel controller	1、Check the travel torque mechanism 2. Re-adjustment of the travel mechanism
