What is a one stem no-pin wafer butterfly valve？

The pinless wafer butterfly valve is a kind of valve that is used to open, close and adjust the fluid channel by the reciprocating rotation of the disc type opening and closing parts about 90 degrees. The pinless wafer butterfly valve not only has simple structure, small volume, light weight, low material consumption, small installation size, but also has small driving torque and the operation is simple and fast. It can also have good flow conditioning function and closing sealing characteristics at the same time. It is one of the fastest developing valve varieties in recent decades.

Advantages of the one stem no-pin wafer butterfly valve：
1.Beautiful appearance
The pinless wafer butterfly valve has no obvious pin head protruding, the appearance looks more beautiful.
2.Convenient maintenance
Due to the way of transferring torque is different, the pinless wafer butterfly valve will be relatively complex in the structure process, but the maintenance and disassembly of the later period are more convenient.
3.Good sealing performance
The overall stem structure, disc and seat sealing spherical contact, so that the torque is greatly reduced. The disc is high precision, polished, and closely matched with seats. It has good sealing performance and has no leakage phenomenon between the stem and the disc.
4.No leakage
The disc adopts pinless connection and the bottom is transmitted to make the center position of the disc more accurate. There will be no leakage phenomenon.
