When designing holes at four corners, consideration should be given to hole spacing, hole center distance, and quality and safety

Attention should be paid to the distance between the opening edge and the oblique angle, as well as the length of the butterfly valve edge, which should be reasonable (not too close or too far apart, arranged reasonably)

The diameter and shape of the upper and lower holes on the four corners may not be consistent.

For example, if the side length is 160 and the distance between the centers of the two diagonal holes is 175, and the diameter of the hole is 18, then the radius is 9

The distance between the center of the hole and the side length is: 18.13-9=9.13MM

The lower hole is elliptical with a length of 35 and a distance of 3.12 from the side length

Being too close may result in quality issues

It should be designed with a side length of 175
