Valsir HDPE is a fusion welded system made up of pipes, fittings and accessories, suitable for all installation types, destined to waste and rainwater drainage.
Valsir HDPE is the ideal solution for installations above ground, thanks to its resistance to UV light; and below ground or embedded in concrete, thanks to its exceptional mechanical characteristics.
Wide range of diameters from DN 32 mm to DN 315 mm, available in SDR 26 and SDR 33.
High chemical resistance to substances dissolved in civil and industrial waste waters.
The pipes are stabilized to reduce dimensional variations and contain carbon black for UV lightresistance.
Resistance to intermittent discharges at temperatures as high as 95°C. High resistance to extremely rigid temperatures as low as -40°C.
Wide range of transition fittings for connection to other waste systems such as cast iron, PE, PP, PVC.
HDPE is completely recyclable and designed according to the principles of Green Building.
Just like our Triplus, HDPE is the only drainage system in the world to be awarded the VERY GOOD rating (double tick) by the prestigious Green Building Council of Singapore.
This certification highlights the very high level of sustainability of HDPE production process; thanks to an extremely careful management of energy, raw materials, water, and waste within a plant that is also certified to ISO 9001, 14001 and 50001 standards, HDPE is one of the most sustainable drainage systems on the market.
The wide range of pipes, fittings and accessories allows a complete waste system to be constructed, from the branches of the sanitary fixtures, to the soil stacks and soil manifold.
Thanks to the numerous jointing systems Valsir HDPE guarantees an easy and versatile installation also dueto the possibility of prefabricating system parts and assembling them on site.
Valsir can supply a waste system with a 110 mm and 160 mm diameter ventilation branch. This is the ideal solution in high-rise buildings where the simultaneous use factor of the sanitary appliances is high
HDPE is a flexible system that was installed all over the world.
The range is manufactured to European Standard EN 1519 and has been certified by the strictest certification bodes.
