This is an inquiry message about Question regarding valve drawing in the 108th China Canton Fair. (这是一条买家关于"Question regarding valve drawing"的询盘信息,来自第108届中国广交会。)Inquiry Message (询盘信息) Question regarding valve drawing We recently pulled a check valve apart during a routine inspection. After reassembling it was noted that the hinge pin fell out during inspection. After reviewing the drawing we noticed a call out for a set screw, which would indicate the pin should not have fallen out. The pictures taken of the valve could not determine if there was a screw installed or not. I was wondering if I could get more information about the set screw. Our drawing just calls it out and includes no other information. If needed, I can email the valve drawing. Valve# 6073W-59-008.
