Dual Disc Check Valves

The chief function of this type of valve is to avert backflow so as to prevent water in a pipe-line from getting contaminated. It is named so because it has two check valves arranged in a series in the device. It generally operates in two different ways. Either one of check valve operates while the other is packed wide open or one of the valves gets closed minimizing the differential pressure of the other thus seals up tight to prevent leaking.

Our wide range of Dual Disk check valves include fully Rubber lined Disk Valve, Unlined Body Disk Valve, and Dual Plate Non-Return Valves etc. They can be installed horizontally as well as vertically.

These valves are sturdily manufactured using quality raw-materials. They are precisely engineered for excellent performance and durability. They offer maximum safety and are very cost-effective.
