High resistance pipes with triple layer wall in high modulus polypropylene (PP-HM) for non-pressure underground sewage applications, internal walls are RAL 8023, internal are RAL 9003.
Molded and thermoformed fittings in compact PP-HM, brick colour RAL 8023. The use of PP-HM allows the production of a high performance system in terms of resistance to loads, buckling and internal and external abrasion.
The PP Ecoforte system complies with European Standard UNI EN 13476-2:2008.
The system provides a wide range of accessories to achieve an efficient sewer system.
Long service life of the entire system composed of pipes and fittings.
Breakage and crushing resistance due to dynamic stress. Flexibility that allows the pipe to withstand the intense pressure caused by burial in the ground and the passage of vehicles.
The system’s mechanical resistance even at low temperatures (resilience) -10°C +95°C intermittent, allows handling of pipes and fittings without breakages, as prescribed by European Standard EN 1411.
The wide range of diameters (from 110 to 500 mm) allows use in all types of constructions: residential, road and industrial. Ring stiffness classes SN4, SN8, SN12, and SN16.
Socket coupling system with blocked Forsheda Din-Lock® for the entire series.
The PP Ecoforte sewer fittings for non-pressure underground pipes are designed to convey:
The Valsir fittings are produced with compact PP-HM with the addition of mineral loads.
The pipes and fittings are connected using push-fit couplings with elastomeric triple-lip bi-component seal (TPV-E and PP) Forsheda 582 Din-Lock® type.
The PP Ecoforte sewer fittings for non-pressure underground pipes are designed to convey:
The Valsir fittings are produced with compact PP-HM with the addition of mineral loads.
Measurements and geometrical data of the products are guaranteed according to UNI EN 13476.
The majority of fittings are made using molding technologies, whereas the larger diameters are made using thermoforming.
The pipes and fittings are connected using push-fit couplings with elastomeric triple-lip bi-component seal (TPV-E and PP) Forsheda 582 Din-Lock® type.
The jointing system with blocked seal allows for an easier insertion and guarantees stability of the seal during the connection of large diameter pipes.
This coupling system absorb movements in the ground.
When two pipes are pushed together, the sealing element is designed to deform, creating a seal by acting both on the joint and on the socket.
Climate change and the increasing urbanization of land can cause overload problems in sewer networks with the consequent risk of flooding.
To prevent such risks it is necessary to install non-return single or dual plate valves.
The valve is installed outside the house, along with a trap, and positioned inside a gully to guarantee an easy inspection. It is made of a resistant ABS and is available in diameters 110 to 200 mm.
The range of traps with dual inspection cap is available in diameters from 110 to 400 mm.
The trap should be installed together with a non-return valve positioned inside a gully. The dual cap allows for simple access and cleaning.
The manholes allow the inspection of the sewer pipes in order to collect samples or to clean when necessary. The manholes in this range do not allow access to people.
The inspection chambers have a diameter of 1100 mm and an inlet from 640 mm allowing the access of qualified personnel for inspection.
The chamber contains steps as established by the standards to facilitate access; they are made of HDPE and are monoblock, they ensure a rapid and safe installation, as well as simple handling during transport.
Available in different heights, up to 5080 mm, they allow the inlet and outlet of pipes of different diameters. The larger diameter chambers are triple layer to guarantee greater resistance to pressure created by the surrounding earth.
Valsir provides complete support both during the planning phase and on site, thanks to a first-class technical office made up of a team of highly experienced engineers, capable of dealing with the most complex system requirements.
