Product name：Soft Seal Butterfly Valves
Product Overview
The soft seal centerline buttress butterfly valve developed by our factory, double eccentric flange butterfly valve with compact structure, easy 90℃ rotary switch, reliable seal and long service life, is widely used in waterworks, power plants, steel mills, paper making, chemical industry, catering and other systems of water supply and drainage, as regulation and cut-off use.
Product features
1、The valve adopts double eccentric structure, has the sealing function that the more it is closed, the tighter it is, and the sealing performance is reliable.
2、Stainless steel and nitrile oil resistant rubber are used for the sealing surface material, with long service life.
3、Rubber sealing ring can be located on the valve body or on the butterfly plate, which can be applied to different characteristics of the media for users to choose. 4、The butterfly plate adopts the frame structure, high strength, large over-flow area, small flow resistance.
5、The whole baking paint, can effectively prevent rust and corrosion and can be used in different media as long as the sealing valve seat sealing material is changed.
6, the valve has a two-way sealing function, installation is not controlled by the flow direction of the medium, but also not affected by the space position, can be installed in any direction.
7、The valve has a unique structure, flexible operation, labor-saving and convenient.


Product name：Three eccentric butterfly valve
Product features
1、The elasticity of the composite metal seal makes the valve have zero leakage performance.
2、Torque seal ensures continuous two-way zero leakage of the valve.
3, The right angle rotation frictionless design is achieved by a unique triple eccentric principle which eliminates friction between the seat and seal in the 90 switch rotation.
4, STL one-piece hard face valve seat can meet many working conditions, service life and easy maintenance.
5, one-piece casting (plate welding) body, structure length in accordance with ISO5752, ASMEB16.10 and API609, can replace high-performance butterfly valves and other types of valves, simple installation, flexible all-metal structure plus zero leakage performance, so that the valve has 'intrinsic fire safety' characteristics.
6、Stem anti-blow-out design is safe and reliable, fully compliant with API609.
7、The valve position indicator on the stem and the top mounting flange are conducive to butterfly plate position indication.
8、The stem of the triple eccentric butterfly valve adopts a through-shaft structure, and the connection between the stem and the butterfly plate adopts a key or pin key set.
