KOSEN Bellows sealed globe valve introduced advanced foreign technology, using double bellows design, welded to the valve stem to maintain stable operating performance, avoid the valve vibration caused by valve plug vibration. At high temperature, the stem does not touch the medium to ensure zero leakage of the stem. At the same time ensure enough strength and toughness, can switch tens of thousands of times. The handwheel is ergonomically designed, with longer service life and easy and convenient operation. The opening and closing of the bellows cut-off valve is a plug shaped valve. The seal face is flat or cone, and the valve is moving straight along the center line of the fluid. It is the most widely used valve. It is popular because of the small friction between the sealing surfaces in the process of opening and closing, which is relatively durable, the opening height is small, the manufacturing is easy, and the dimension is easy to make. It is convenient not only for medium and low voltage but also for high voltage. Widely used in food, medicine, petroleum, chemical industry, natural gas, iron and steel, environmental protection, papermaking and other transportation pipelines to cut off or circulate medium.
