Features :

Bellows sealed globe valve is simple in structure and good in performance.
The stem nut adopts surface nitriding to improve the surface hardness .
The medium flange bolt is made of high-strength alloy steel, with the ability to resist high temperatures.
Double sealing of packing and bellows to achieve zero leakage.
The bellows is designed in the inner cavity of the valve cover, which avoids direct flushing with the medium and improves the service life of the bellows.
The bellows adopts 2~4 times overlap to prevent the valve leakage due to the damage of the single layer of the bellows, and prolong the service life of the valve.
