Sewage Defence

Passive and automatically deployed, Flood Angel Non-Return Valves protect from sewage & waste water

FLOOD ANGEL® 160/110mm Non Return Valve

  • Slide 1
  • Slide 2

The 160mm/110mm Non-Return Valve is a passive flood protection system and is the only rod-able backflow valve on the market.
The Non-Return Valve 160mm/110mm protects basements and ground floor rooms against flooding caused by return flow of sewage waters. Such risk occurs most often in sanitary drainage systems connected to combined sewerage systems and in rainwater drainage systems. It may be caused by intense rainfall, thaw or flood.

  • A passive flood protection system
  • The only rod-able backflow valve on the market
  • Virtually maintenance free
  • Available to fit 100mm diameter drainage pipe
  • It’s always open position allows unrestricted free flow
  • May be installed in main-drain or branch
  • Economic property protection – usually only one valve needed per household
  • Over 40,000 of these award-winning products have been successfully installed
  • 2 year manufacturer’s guarantee

BENEFITS

AUTO-CLOSES
The 160mm/110mm Non-Return Valve uses the power of the flood water to close itself. Once waters subside, the Backflow Valve opens again.

In normal operation the system is fully open allowing solids to flow freely and unrestricted through the valve, the efficiency of movement is also improved by in-built flow wings in the valve body.

Because of its fully open design the valve offers no restriction to cleaning rods, which facilitates drain maintenance and the clearing of blockages further down the branch. Air is allowed to circulate freely through the valve and drainage system eliminating the risk of gas build-up or smells.

In the event of water surging back through the pipes or in flood conditions, the backflow automatically lifts a gate within the valve which shuts against a neoprene gasket seal and prevents backflow past the valve.

MAIN or BRANCH
May be installed in main drain or at branch.
