Our company is the production of Triple offset butterfly valve, and I am the designer of our company, although our work does not seem so busy, but do the design work the heart must be fine, otherwise to when Triple offset butterfly valve to produce a liability issues will find our design, because drawings are we out ah! So sometimes I often go to the workshop a turn, found the problem, if it is wrong we design department, so we just did not give the company before they cause greater losses to save it, or when the time came after the Group boss also angry, to the time that the design department manager I would not hold up ah.
