Kindly let us know the 2 new nos of APL valve have received?
Are both units fix?
We look forward hearing from you again.
As for the faulty valves, our factory engineer has already evaluated the root cause.
They tested the dimension of the APL base and found out the APL base has an eccentricity of 0.3mm.
It resulted in the not-so-smooth rotation of the APL knob.
However they are sure it is a single case fault. They will make sure it won’t happen again.
Thanks for your feedback earlier on.
