Bellows control valve

The bellows control valves provided by Viti Industry can meet the zero leakage standard and are very safe and reliable. The service life is much longer than that of ordinary control valves. There is a layer of metal barrier at the valve stem seal, which can be used in high-demand working conditions where isolation is required inside and outside the valve, such as oxygen. Bellows have the function of expansion and contraction and are not affected by thermal expansion and contraction. They have very obvious advantages in situations where the temperature gradient of the medium changes greatly. The valve features double sealing. When the bellows is intact, the packing is completely isolated from the medium, which effectively protects the packing and significantly extends its service life.
