Second, the main features of soft sealed pneumatic flanged butterfly valve:
1. The valve adopts a double eccentric structure, which has a tighter sealing function and a reliable sealing performance.
2. The sealing accessory material is matched with stainless steel and nitrile oil resistant rubber, and has a long service life.
3. The rubber sealing ring can be located on the valve body or on the butterfly board. It can be used for different characteristics of the medium for the user to choose.
4. The butterfly plate adopts a frame structure with high strength, large flow area and small flow resistance.
5, the overall paint, can effectively prevent rust and can be used for different media as long as the sealing seat sealing material is replaced.
6. The valve has a two-way sealing function. It is not controlled by the flow direction of the medium during installation, and is not affected by the spatial position. It can be installed in any direction.
7. The valve has unique structure, flexible operation, labor saving and convenience.
