AWWA C504 Ductile Iron Double Eccentric Butterfly Valves
Basic Info of Awwa C504 Butterfly Valve
- AWWA C504 is designed to ensure the reliability and functionality of rubber seated butterfly valves used in water supply systems.
- Good sealing performance: The double eccentric design of awwa c504 butterfly valve keeps the contact surface between the valve seat and the valve plate at one point, effectively avoiding friction and wear between the valve seat and the valve plate, thereby providing excellent sealing performance and preventing medium leakage.
- Corrosion resistance: The eccentric butterfly valve body and valve plate of the electric double eccentric flange butterfly valve can be made of corrosion-resistant materials, which can adapt to the requirements of various corrosive media and extend the service life of the valve.
- High flow capacity: Due to the characteristics of the double eccentric design, the valve plate of the electric double eccentric flange butterfly valve will not cause friction with the valve seat during the opening process, and can provide a large flow capacity and is suitable for systems requiring large flow rates.
