TANK FLOOR CHECK VALVE/ PROTECT STRUCTURES FROM MECHANICAL DAMAGES IN THE EVENT OF RISING TABLES OR GAS PRODUCT ADVANTAGES •  Innovative: patented product, no moving parts. •  High-performance: flow rate up to 5000 l/h. •  Watertight: no backflow once the water table subsides. •  High resistance: backpressure, corrosion, mechanical compression, UV, sewerage, etc. •  Light and compact: easy and quick installation. •  Reliable: durable materials without moving parts. UNIQUE SOLUTION PATENTED PRODUCT N° 2687633 COUPLINGS & SEALS NON-RETURN & FLAP VALVES

TANK FLOOR CHECK VALVE/ PROTECT STRUCTURES FROM MECHANICAL DAMAGES IN THE EVENT OF RISING TABLES OR GAS The first FLO-PLUG® (FLO-PLUG® 1) was developped and patented by NORHAM in 2007 in order to propose a professional solution to protect structures from mechanical damages in the event of rising water tables or gas. FLO-PLUG® 2 is a major evolution of the first generation. 127 mm Still no moving parts and with a rethought design, the self-contained safety unit FLO-PLUG® 2 can withstand flows 10 times FLO-PLUG® 1. FLO-PLUG® 2 takes the FLO-PLUG® concept to a higher level. AREA OF USE • ...

TANK FLOOR CHECK VALVE/ PROTECT STRUCTURES FROM MECHANICAL DAMAGES IN THE EVENT OF RISING TABLES OR GAS CONCEPTION PP homopolymer with anti-UV protection+EPDM, materials chosen for their high resistance (backpressure, corrosion, mechanical compression, UV, sewerage, temperatures from -40° C to +95° C). Self-cleaning To minimise sticking of sediment. Bottom view. PP Homopolymer with anti-UV protection Anti-adhesive material to limit formation of deposits. Rethought and patented orifices opening To allow maximum through flow. New profiled membrane Optimised to allow maximum through flow but...

TANK FLOOR CHECK VALVE/ PROTECT STRUCTURES FROM MECHANICAL DAMAGES IN THE EVENT OF RISING TABLES OR GAS CALCULATING THE FLO-PLUG® QUANTITIES The number of FLO-PLUG® 2 to be installed is defined according to the following two criteria: 1. minimum 1 x FLO-PLUG® 2/150 m²; 2. depending on the rise rate*. Minimum 2 x FLO-PLUG® 2 per basin. The table below includes these two criteria. For a surface of 1000 m²: •  0,5m/day known maximum water rising for table: use 7 FLO-PLUG® 2; •  or 1m/day known maximum water rising table: f use 9 FLO-PLUG® 2. *If the rising velocity is unknown, take the usual...
