OTTIMA Válvulas antirretorno
Non-return valves


A solution to flooding problems, with a completely new design.

Easy to install in reduced spaces thanks to its compact design.

The easiest and most economic solution to avoid flooding problem is the installation of a Non Return Valve.This will protect homes from costly damage, whose resolution are always the owners responsibility.

OTTIMA has to be installed on waste water pipes and allows the outflow to reach the municipal sewage network avoiding water backflows.

 It is highly recommended in cases of:

  • Fields which are under the water level
  • Areas closest to rivers, lakes, sea
  • When the sewage is linked to rainwater pipes (dangerous in case of heavy rain)
  • If a sewage network overload has already occurred
  • If an extension of the sewage network (with consequent overload) is probable
  • When the municipal sewage network includes pumping stations.

In a normal situation, sanitation water flows through non-return valve pressing to the internal flapes flow rate direction, to the valve outlet (male part).
In a torrential rain situation, when the suplly is subject to flow rates that filling it and this big underflow tends to penetrate in an opposite way than the usual, flape takes action, preventing from entering indoor.
