Newsway valve bellow sealed globe valve Structure of components of bellows globe valve are similar to common globe valve except that its valve stem seal structure is special.
When bellows globe 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.
The valve stem of bellows globe valve adopts double seal structure of bellows and stuffing to guarantee no leakage sealing at valve stem.
The valve is particularly applicable to industrial pipeline for flammable, explosive, toxic, strong penetrability, nuclear radiation, nuclear power project and ship confined space and other special medium and severe conditions.
