The processing technology of Sanitary Valve is as follows:

1. Rolling method: generally no mandrel is used, suitable for the inner round edge of thick-walled tubes.

2. Roller method: place a core in the tube, and use rollers to push the outer periphery for round edge processing.

3. Punching method: use a tapered core on the punch press to expand the tube end to the required size and shape.

4. Forging method: use a forging machine to punch out the end or part of the stainless steel pipe fitting to reduce the outer diameter. Commonly used forging machines are rotary, connecting rod, and roller.

5. Bending forming method: There are three commonly used methods, one method is called stretching method, another method is called punching method, and the third method is roller method, which has 3-4 rollers, two fixed rollers, and one adjustment roller. Adjust the fixed roller spacing, and the finished pipe fitting is bent.
