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.
This innovative waste system guarantees excellent ventilation of the waste stack and branches on each floor, limiting pressure fluctuations in the system.
This system also offers significant advantages in terms of money savings thanks to the possibility of constructing single stacks (therefore without installing parallel ventilation) in one single diameter, either 110 mm or 160 mm with double the draining capacity as compared to systems with primary ventilation.
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.
The pipes are stabilized to reduce dimensional variations and contain carbon black for UV light resistance.
Wide range of transition fittings for connection to other waste systems such as cast iron, PE, PP, PVC.
High chemical resistance to substances dissolved in civil and industrial waste waters
Resistance to intermittent discharges at temperatures as high as 95°C.
High resistance to extremely rigid temperatures as low as -40°C.
