This process ensures a long working life of the pipe. The silanes method (PE-Xb) is used far crosslinking the two layers of Pexal. C0MPRESSI0N FITTINGS Compression fittings combine the positive feature of high reliability with a simple installation technique,in facı these fittings do not require special tools. The permanent pipejoint is achieved bycompression, in facı bytightening the nut againstthe coneshaped olive, the profiles of the two pieces are designed to cause a progressive shrinkage of the cone olive and to distribute the compression forces across all the contact surface. Pressfittings have been designed to further simplify the installation operations, by significantly reducing the time required tor assembly. This technique alsa causes the pipe to deform permanently by compression,which is achieved by the action ofa pressing machine fitted with suitable jaws; the machine operates by permanently deforming a ferrule suitably sized to ensure pressure is exerted even when temperature changes occur. r �exal easu Fruit of Valsir's vasi experience in the technology of multi-layer pipe and fittings, an advanced product, innovative both in its conception and its use. An even easier and safer system! PEXAL EASY is an advanced system of fittings in PPSU, a polymer, or more appropriately, a new generation "technopolymer", the numerous characteristics of which, make the new PEXAL EASY fittings comparable in performance and quality to brass fittings! valsiır® VALSIR S.p.A. - Localita Merlaro, 2 - 25078 Vestone (Brescia) ltaly - Tel. +39 0365 877011- Fax +39 0365 870820 - lnfo: valsir@valsir.it
