butterfly type valves

Main Features: For the structure of the triple-eccentricity seal butterfly valve, when the valve is under the complete open state, its butterfly plate sealing face will break away from the valve seat sealing face completely; when it is opened from 0 to 90°, the butterfly plate sealing face will...

Product Details

Butterfly Type Valves

Valves size from 2" to 48", and connection ways can be lugged or semi-lugged wafer style, double flanged style, single flanged style, etc. Working pressures range can be from 150 to 250 psig. Body materials can be cast iron, ductile iron, stainless steel, wcb, etc, and the dis materials can be ductile iron (nickel coated cast iron and nylon coated cast iron are available). Valve seat materials consist of neoprene, silicone, hypalon, viton, buna n, and EPDM.


Sealing Form 

As a component used to realize the on-off and flow control of pipeline system, the butterfly valve has been widely used in many fields such as petroleum, chemical industry, metallurgy, hydropower and so on. In the well-known butterfly valve technology, the sealing structure of the sealing structure is a plurality of sealing structures, and the sealing material is rubber, polytetrafluoroethylene and the like. Due to the limitation of structural features, it is not suitable for industries such as high temperature resistance, high pressure, corrosion resistance and abrasion resistance.
