Soft Seat Low Pressure Concentric API609 4 inch Butterfly Valve For Water
Concentric wafer butterfly valve, manufactured by TEKO, can be rotated to 90 degree to open or close valve, having the advantages of compact construction, reliable seal and long service life. The valve is widely used for water supply and drainage system to regulate or cut-off medium, in chemical industry, food and other industries.
Key Features
1. Adopting stainless steel and oil-resistent nitrile rubber, having long service life.
2. Seal ring can be used on the valve body and disc, which is applicable for different medium as required.
3. Frame structure disc, having the advantages of high strength, large flow area and low flow resistance.
4. The whole valve uses baking finish which can resist corrosion effectively. Otherwise, changing seal materials, the valve can be applicable for different medium.
5. It can be installed in any position without the limitation of medium flow and space.
6. Unique structure, convenient utilization.
