Flat backwater valves
 To
protect against these accidental backflows in public or domestic
sewage lines there are BACKWATER VALVES, which as an exclusive
characteristic constantly remain open while the flow is normal,
but close automatically when they detect any backflow that
may cause overflowing of the sewage at the places, which do
these valves, protect.
While these valves remain open to the flow of liquid discharges,
whether they are contaminated or not by solid loads, the evacuation
is carried out freely, without the valve interfering with the free
circulation of the contents, whatever its pressure or volume of
flow. |
At
the user's will, these FLAT VALVES may be provided with a
manifold top to connect them to an submersible pump, a cleanout
and an access for pressurized water to clean the sediments
when the discharges to be evacuated require it.
