Product Features

The valve body and valve plate are both made of ductile iron casting, and according to its advantages, the structural pressure bearing capacity exceeds that of ordinary gray cast iron. To avoid deformation, valves undergo pressure testing and other tests before leaving the factory. This way, the maintenance cost for customers is lower, which is conducive to establishing a good reputation. The valve body is combined with high-temperature vulcanization technology to prevent direct contact between the medium passing through the interior and the metal. The medium that can pass through can reach 80 ℃.

Worm gear can prevent valve position movement caused by water pressure impact. Key transmission components are immersed in oil for lubrication, while also adapting to harsh outdoor working conditions.

The installation efficiency is high, the labor cost is low, and the on-site design requirements are small, thereby enhancing the competitiveness of the product. The streamlined design of the valve plate can reduce water resistance, and when fully opened, the flow resistance approaches that of a straight pipe.

Application

This ductile iron flange butterfly valve has ultra-high cost-effectiveness and high applicability to working conditions.

Due to its strong resistance to pressure, it has become the best choice for waterworks and sewage treatment plants.

Due to its strong stability and resistance to deformation, flange connections can be used in high-rise fire protection pipelines, central air conditioning cold and hot water circulation, and other scenarios.

Due to its full diameter and low flow resistance design, it has a high transportation speed and can be used in agricultural irrigation, drainage systems, and other scenarios.
