Pneumatic valve electric actuator specifications and troubleshooting

Pneumatic valve electric actuator instructions:

pneumatic valve electric actuator when using, must, in accordance with normal use, if you don't understand operating at random, will lead to harmful pneumatic valves. Is recommended at the time of use, through professional training in the use of, this is advantageous to us. So how to maintain this machine?



1. The way we see it maintenance is need long-term, not short-term. After using the machine, shall check the machine if there is any damage.

2. If damage to the machine, it will affect our use, and we shall have to do is, in a timely manner after the discovery of the problem of maintenance, which can avoid more failure.



here simply under its maintenance way, at the time of maintenance, first of all, pay attention to the use, and our voltage is normal or not.



1. Pneumatic valve electric actuator to voltage also to have certain request, if the voltage is not enough, will damage to the machine, then check voltage, preventing the harm of the machine have you must be aware of this.

2. Under the condition of voltage is not enough to drive the machine, don't go to casual use, it is bad for us.

3. Also, should check the machine whether have noise, or electronic components is a day. If it is found that the two problems. To timely check, don't not to heart. The reason is very simple, because small problems often lead to big trouble, we need to do is check in time, timely maintenance.



in this way, timely notice any produced by pneumatic valve electric actuator dynamics, once has the fault in time to repair, there is no problem.



pneumatic valve electric actuator fault handling methods:


a. Electric actuator motor fixed
the reason: 1. The power cord release, and 2. 3 control circuit malfunction. Travel with torque control mechanism failure.

elimination method: 1. Check the power cord, 2. Out of line fault, 3. Excluding travel or torque control mechanism failure.


2. Output shaft rotate to do not conform to the regulations,
reason: power supply meet the phase sequence.

elimination method: changing any two power cords.


3. Motor overheating
reasons: 1. Continuous working time is too long, 2. A phase is broken.

elimination method: 1. Stop running, make the motor cooling, 2. Check the power cord.







四. Run the motor stalling
reasons: 1. Pneumatic valve is defective, 2. Electric equipment overload, torque control mechanism.

elimination method: 1. Check the pneumatic valve, 2. The torque increases.


5. Electric pneumatic valve in place after the motor does not halt or
light not on reason: 1. Travel or torque control mechanism is faulty, 2. Improper adjustment stroke control institutions.

elimination method: 1. Check the schedule or torque control mechanism, 2. To adjust the stroke control mechanism.


6. Far no pneumatic valve position signal
reasons: 1. Potentiometer gear set screw loosening, 2. Far eastone potentiometer failure.

elimination method: 1. Tighten the potentiometer gear set screws, 2. Check the replacement locator.
