Valsir PP ensures a practical and rapid installation without the use of glues or special tools thanks to the jointing system with push-fit sockets.
The particular shape of the seal and the housing of the push-fit joint guarantee hydraulic tightness and allow the normal movements of the pipe including those caused by thermal expansion.
the thermal expansion of Valsir PP is extremely low compared to the most common plastic materials, a 3 m pipe will expand in length by just 13 mm when the waste liquid flows at a continuous temperature of 60°C.
It is thanks to this low coefficient of thermal expansion that the push-fit joints are capable of absorbing the variations in length of the pipe without taking any particular precautionary measures; it is enough to follow the installation instructions in the Valsir technical manuals.
To allow the use of leftover pieces of pipe, Valsir supplies a bi-joint sleeve. This is a special fitting that allows two pipes without sockets to be connected guaranteeing hydraulic tightness without compromising flow rates.
The range is composed of pipe lengths from 150 mm to 3 m with one socket, two sockets or smooth pipes without sockets. It features a wide choice of fittings and accessories that allow the most diverse system configurations to be constructed.
Diameters range from the smallest such as 32, 40 and 50 mm for the installation of branches on each floor to larger diameters such as 160 mm for the waste manifolds.
The range is made complete with accessories for connection to other Valsir waste systems, accessories for connection to sanitary appliances and anchor brackets.
Wide range of diameters from DN 32 mm to DN 160 mm.
Surface mounting of pipes requires the use of suitable brackets that must withstand the weight of the pipe, the weight of the waste water and the forces that are generated by expansion and contraction.
In relation to the type of bracketing chosen, the so-called guide points and fixed points (or anchor points of the pipeline) must be provided. In all cases, if the waste system is required to reduce noise then sound reducing brackets with anti-vibration rubber must be used.
Valsir PP is a waste system made up of pipes, fittings and accessories for the construction of waste and rainwater drainage systems.
Valsir PP is an extremely light system and thanks to the push-fit socket with hydraulic seal it represents the most simple solution for the construction of waste and drainage systems.
Valsir PP is manufactured to European Standard EN 1451 and can be used for waste systems at low and high temperatures, ventilation systems for waste networks and for rainwater drainage systems inside buildings for civil and industrial use, hospitals and hotels.
The wide range of pipes, fittings and accessories allow the entire waste network to be made, from the branches to sanitary appliances to the stacks and waste manifolds.
Light weight and extreme ease of installation on site without the aid of special tools, thanks to the push-fit connection. Furthermore, the push-fit socket does not require the use of harmful glues or solvents.
Corrosion and abrasion resistance.
Resistance to intermittent discharges at temperatures as high as 95°C.
High chemical resistance to the substances dissolved in civil and industrial waste waters.
Wide range of diameters from DN 32 mm to DN 160 mm.
Wide range of transition fittings for connection to other waste systems such as cast iron, PE, PVC.
The product, its recyclability and the production processes used are based on Green Building principles, in respect for the environment and forthe conservation of resources.

The advantages of the PP system installed in great buildings all over the world.
The range has been certified by the strictest certification bodes.
Surface mounting of pipes requires the use of suitable brackets that must withstand the weight of the pipe, the weight of the waste water and the forces that are generated by expansion and contraction. In relation to the type of bracketing chosen, the so-called guide points and fixed points (or anchor points of the pipeline) must be provided. In all cases, if the waste system is required to reduce noise then sound reducing brackets with anti-vibration rubber must be used.
If the waste system is constructed using Triplus® or Silere® then the employment of sound insulating pipe brackets is essential.
Guide points are created using brackets which, as well as supporting the weight of the pipe, they also allow the axial movement of the pipe, preventing it from flexing due to the increases in length caused by heat expansion, following increases in the temperature of the room and the waste water.
Guide points are created when the bracket is not tightened completely around the circumference of the pipe, giving it free axial movement
Fixed points are also called anchor points and are created in order to prevent any movement of the pipe in the area where the bracket has been fixed. The aim of the fixed point is to divert the variations in length of the pipe in the desired direction, that is, towards the ring seal sockets, the expansion sockets or towards the compensation deflection arms.
Fixed points are usually achieved by using suitable brackets that are closed tightly around the circumference of the pipe.
Valsir Collarwings is the new range of fire-stop sleeves produced in compliance with the most recent standards and suitable for different types of plastic pipes. Collarwings fire-stop sleeves are made of steel that is painted using polyester powder, coupled with special intumescent elements that, in the presence of fire, expand and squeeze the pipe thus preventing the passage of flames, vapour and combustion gas and acting as a form of thermal insulation.
The seal is completely inaccessible thanks to the particular shape of the housing.
The joint guarantees total bore passage thanks to the absence of reductions in the section.
