●VMV forged bellows sealed globe valve, in addition to the advantages of ordinary bellows globe valves, its valve body has a more uniform structure, better density, smaller dimensional error, and better strength integrity compared to castings.
●The oriented structure has higher performance in terms of overall strength and stress than castings. In areas with severe stress and intergranular corrosion, this valve ensures a long service life and trouble-free performance.
●The valve adopts conical sealing, and no impurities remain on the sealing surface. When approaching closure, the sealing surface has a self-cleaning effect. The conical sealing surface can amplify the sealing force when the axial force of the valve stem is converted, resulting in better sealing performance.
●Bellows plus packing double seal design, with double insurance, makes the seal at the valve stem safer and more reliable, and complies with international sealing standards.
●All bellows are 100% tested for fugitive emissions according to ISO15848 Class A standard at the factory. All bellows components and valves are 100% tested to standard Class A to ensure zero leakage.
