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.
