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.
