17-4ph 630 butterfly valve stem

Stem

Although the stem is a very small item when compared to other parts of butterfly valve, it is crucial for the function of the valve. The stem is used for connecting the disk inside the valve to the handle that is positioned on the outside. It enables the butterfly valve to open or close.

Stems are available with two different designs related to the protection of the stem:

·         Wetted

Wetted stems are vulnerable to corrosion and erosion and don’t contain materials in their design to protect them from such problems. That is why it should be made of materials that are compatible with the media that are going to flow through the line.

·         Non-Wetted

This stem has been designed in a way that is protected from erosive or corrosive liquids that are running in the line.
