Gear OP Double Flanged Ducitle Iron Butterfly Valve
Basic Info
- Butterfly valve with Worm Gear: Proper worm gear speed ratio can reduce the force required to open and close the valve.
- Ductile iron butterfly valve with DI body/disc: GGG50 butterfly valve is the most commonly used butterfly valve, which has high tensile strength and good anti-corrosion characteristic.
- Vulcanized valve seat: A special manufacturing process is adopted, in which the rubber and the double flanged valve body are integrated through high-temperature vulcanization. This method makes the valve seat and valve body tightly combined and difficult to separate.
- Two stems type：make the disc flat and allow more flow, less resistance to the flow and more mechanical resistance.
- Efficient Flow Control: This ductile iron butterfly valve with worm gear is designed to quickly and effectively control the flow of fluid when opening and closing. The butterfly plate inside the valve can rotate 90 degrees to fully open or close the valve. This design provides lower flow resistance, allowing for higher flow rates and more efficient fluid control.
- Simple Installation: The Flanged Butterfly Valve features a double flange design that can be easily installed between flanged pipe connections. This design makes installation of the valve easier and faster, reducing possible problems and delays during installation.
