FBGX (D342X) Worm Gear Drive Soft Seal Butterfly Valve
Product number:FBGX (D342X)
product description:

  The soft sealing centerline wafer butterfly valve developed by our company, the double eccentric flange butterfly valve has compact structure, easy 90° rotary switch, reliable sealing, and long service life. It is widely used in water plants, power plants, steel plants, papermaking, chemical industry, etc. It is used for regulation and cut-off in the water supply and drainage of food and other systems.

Features:


1. This valve adopts a double eccentric structure, which has a tighter sealing function as it closes, and its sealing performance is reliable.
2. The sealing material is matched with stainless steel and nitrile oil-resistant rubber, which has a long service life.
3. The rubber sealing ring can be located on the valve body or on the butterfly plate, which can be applied to different characteristics of media for users to choose.
4. The butterfly plate adopts a frame structure with high strength, large flow area and small flow resistance.
5. The overall baking varnish can effectively prevent corrosion and can be used for different media as long as the sealing material of the sealing valve seat is replaced.
6. This 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. This valve has unique structure, flexible operation, labor saving and convenient.
