1. Why is there no sound or no sound after some rotary valves are welded?

This situation may be due to the excessive power density of the soldering iron that can be used during the soldering process (20-30W soldering iron is recommended) or the time may be too long, causing the solder joints between the pins of the rotary valve and the coil to be heated and melted.

2. Why do some rotary valves have a low, silent or sandy tone after welding?

This situation may be that the current to start the rotary valve is too small or too large, causing the rotary valve to fail to sound normally.

3. Why do some rotary valves change or become silent after being used for a period of time?

This situation may be that the continuous beeping time of the rotary valve is too long (the continuous calling time of the rotary valve should not exceed 8-10 hours, otherwise it will change the sound or burn) or may be affected by the environment.

4. Why does the rotary valve of some manufacturers not sound before installation?

This is because the quality of the rotary valve itself is poor. In this case, the split type uses soft encapsulation to start, and there are more chances of occurrence. The performance of this type of rotary valve is unstable and is obviously affected by the environment, such as vibration during transportation, welding on the production line, and high temperature ( 60 degrees) or too low (-20 degrees) environment; and poor anti-interference, such as surrounding magnetic components. These will affect the sound quality of the rotary valve.
