Under normal operating conditions the Flood Angel® 160mm/110mm Non-Return Valve is fully open allowing solids to flow freely and unrestricted through the valve. In flood conditions when water surges back through the drainage system the gate is automatically deployed by the hydraulic pressure of the water. The gate is sealed against a neoprene gasket and this prevents backflow past the gate.
Inspection and maintenance is made easy with a fully rod-able system and a clear inspection lid. Sewage backflow can cause untold damage resulting in long term consequences and high clean up expenses. This can be prevented using this simple yet effective product.
The Flood Angel® 160mm/110mm Non-Return Valve uses the power of the flood water to close itself. Once waters subside, the Non-Return Valve opens again.
Easy installation and virtually maintenance free.
May be installed in main drain or at branch.
