Bellows Valve

Description:

This product is often applied to the occasions where we have demanding requirements for stem seal, such as high vacuum and nuclear industry. The stuffing box on normal valves is replaced by the bellows on this new bellows valve. The stuffing and the bellows can be used together. This new design can ensure the stem no leakage. The leakage of radioactive substances or valuable materials can be prevented. It can also keep high vacuum. The corrugated pipe can rise and fall with the valve rod. The maximum working pressure of this bellows valve is determined by the bellows compression strength and fatigue strength.

Advantage:
1. This new valve adopts double seals design. If the corrugated pipe seal will be failure, the stem packing seal can also avoid the external leakage. This design is in accordance with the international seal standard;
2. The bellows valve can reduce the energy loss and improve the equipment safety;
3. This product has long service life and the maintenance time is reduced;
