Bellows valve is a kind of valve that takes bellows as valve stem seal element. It is commonly used for application with strict valve stem sealing requirement, such as high vacuum application and nuclear industry. Replace stuffing box in common valve with bellows or use with stuffing box can make no leakage at valve stem part to prevent leakage of radioactive material or valuable material, or maintain a high vacuum. Bellows extends and retracts with lifting of valve stem. The maximum working pressure determined by compression strength and fatigue strength of bellows.

1. Structure of components of bellows gate valve are similar to common gate valve except that its valve stem seal structure is special. 2. When bellows gate valve is open, the bellows is compressed, the adverse sealing pair of valve stem and valve cover limits stroke of valve stem to prevent that deformation of bellows exceeds its own limits and causes damage. 3. The valve stem of bellows gate valve adopts double seal structure of bellows and stuffing to guarantee no leakage sealing at valve stem. 4. The valve is particularly appli..
