One of the key elements of the system is the Rainplus® outlet that has been designed and manufactured to meet the requirements and testing criteria set by the international standards EN 1253 and ASME A112.6.9.
The main components of the Rainplus® outlets are made of stainless steel or molded aluminium alloy, protected by a special resin making them long-lasting
These are the main features.
Wide range of drainage flows (up to 65 l/s with Rainplus® 110 and up to 14 l/s with Rainplus® 56);
reduced roof water levels required to trigger the siphonic action;
no swirls thanks to the special profile of the anti-vortex disk and reduced pressure losses at the inlet;
low noise levels and maximum operation stability;
easy installation thanks to the reduced number of components and compact size. For example, Rainplus® 56, in the version with horizontal connection, can be installed inside the roof slab thanks to a height of just 104 mm;
connection with the Valsir HDPE system is extremely reliable;
suitable for installation in gutters, even of small dimensions, or on roofs covered with any type of waterproofing material.
Rainplus® Overflow Kit
Local regulations or standards on the design of rainwater systems may require emergency systems (also known as overflow systems) able to drain unexpectedly intense rainfall exceeding the design rainfall level.
Valsir supplies a patented product that allows a Rainplus® siphonic outlet to be transformed into an emergency siphonic outlet by simply adding an Overflow Kit that is adjustable in height and capable of maintaining the same drainage performance.
Valsir offers a wide range of bracketing systemsand accessories to install the entire drainage network. The Rainplus® bracketing system, composed of special clips as well as support rails and relative accessories, is designed to resist the forces of heat contraction and expansion in the drainage network and is available in diameter 40 mm up to diameter 315 mm.
The Rainplus® system also includes clips with M10 expansion anchors, clips for M10 threaded rods for mounting on support rails, clips for 1/2” and 1” threaded rods for wall and ceiling mounting.
The bracketing system range allows:
rapid and simple ceiling mounting of long stretches of collector pipes;
mounting of the entire drainage network using a reduced number of bracketing pieces;
alignment of clips and Valsir HDPE pipes with the support rail;
capacity of absorbing heat expansion and contraction of the drainage network; installation without special tools;
the clips are anchored to the pipes and support rail using high resistance bolts
PIPES AND FITTINGS
The advantages of using the Valsir HDPE system
The Valsir HDPE product line has been developed conventional and siphonic drainage systems and
it is characterised by a wide range of fittings such as access pipes, elbows, reducers and reduced branches.
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.
Possibility of prefabrication to reduce assembly time on site and possibility of creating special pieces for particular applications and solutions.
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.
Excellent abrasion resistance and mechanical strength.
Highly versatile and easy to install thanks to its light weight and numerous connection methods that allow wastage to be reduced to a minimum.
Wide range of transition fittings for connection to other waste systems such as cast iron, PE, PP, PVC.
The completely recyclable product and the production processes used are all based on the Green Building principles, respecting the environment and conserving resources.
