The bellows valve is often used in locations where the sealing performance of the stem is severely required without any external leakage permitted. The bellows valves of CSV Company include bellows gate valves, bellows globe valves and bellows ball valves. The bellows valve can enhance the sealing performance at the stem part, eliminate the looseness and leakage caused by rotation movement of the stem and protect the stem from being corroded by the medium and endow the stem with the feature of dual packing sealing. It is suitable for such industries as polyester, chemical fiber, heat medium pipe, high vacuum and nuclear industry.
