INTROUTION P VVS The principle applications for flap valves are for surface water drainage associated with river, estuary and sea water outfalls to prevent backflow into the sewer and for final effluent outfalls from wastewater treatment works to prevent flood damage within the works. NON-RTURN VVS Non return valves or backwater valves are used within sewerage and drainage systems to eliminate the risk of flood damage by the backflow of sewage or flood water into properties through low level entries such as low level drain gullies, toilets and washing machine outlets. The nvironment gency in their publication on damage limitation for properties at risk from flooding and the Government guidance note Preparing for loods both recommend the installation of non-return valves (anti-flooding devices) on all such drains and sewers. The uilding Regulations 2000, pproved ocument, recommends the installation of non-return valves on drains from basements in low risk areas and on all drains in areas with a high risk of flooding or sewer surcharge. These valves are also used in commercial and industrial application where non-pressure flow control is required (e.g. fish farming) MTRIS P VVS ody & flap - Glass reinforced plastic using a isophtalic polyester resin with surface isophtalic gel coat inge - Self lubricating rtacetal plastic Seal - thylene Propylene iene Monomer (PM) to S N 1-1 Optional nitrile (NR) seal available ittings - Grade 1.01 (31) austenitic stainless Steel to S N 100-2 NON-RTURN VVS RI (N100 to 00) ody & lap - PVu Seal - thylene Propylene iene Monomer (PM) to S N 1-1 Norham (N to ) ody & flap - Glass reinforced plastic using a isophtalic polyester resin with surface isophtalic gel coat inge - Self lubricating rtacetal plastic Seal - thylene Propylene iene Monomer (PM) to S N 1-1 Optional nitrile (NR) seal available ittings - Grade 1.01 (31) austenitic stainless steel to S N 100-2 2 RUR UK The Original and est - Rubber lexible ouplings and ushes
NON RTURN VVS RI N100 to N00 range of PVu non return valves complying with the requirements of S N 135 - nti-flooding devices for buildings. Sizes N100 to N200 are certified by the German Institute G. These valves are watertight to a pressure of 0.5 bar (5m ead). These valves have a spigot and socket with integral seal as standard for direct connection to solid walled PVu pipe but double spigot versions are available to special order for sizes N00 and above. They can be connected to other pipe material using Mission Rubber lexible couplings (see separate technical brochure).

GNR OTIONS lap valves should be fixed so as to avoid the accumulation of debris around the invert which could prevent the valve operating correctly. TI OTIONS Turbulaence of flow due to severe wave action will shorten the working life of a flap valve. Therefore it is recommended that careful consideration is given to the positioning of valves and they are installed within an outfall bay or otherwise protected from direct wave action by baffles. or more information please contact us Tel: +(0)11 257 000 ax: +(0)11 257 1122 mail: sales@missionrubber.co.uk Mission Rubber (UK) imited, Units +5, tlas usiness Park, Starnhill lose, cclesfield, Sheffield, S35 9TG www.missionrubber.co.uk
