The above form is our company bellows specifications of the part,Some specifications have many types of wave distance and the thickness of the material, Non-standard specifications according to the drawing or parameters can be customized.
Using Bellows instead of normal valve of the stuffing box or and stuffing box are used together,Can make valve rod position without leakage,Used to prevent radioactive substances or valuable substances leakage,or keep high vacuum . Bellows along with the valve rod rise and fall of stretch out and draw back,The bellows compression strength and fatigue strength decided the highest working pressure of the valve.
The excogitation of the Stop Valves introduce bellows seal,To completely eliminate the common valve stem packing seal of the aging fast, easy to let the cat out of the faults,Not only increased use of energy efficiency ,increase production equipment safety ,reduce maintenance costs and frequent maintenance ,and provide clean and safe work environment.
Batch quantity supply Bellows components valve rod and welding -use for Bellows valve (AD02010
