Pexal XL is the innovative modular fitting system produced by Valsir. Thanks to a diameter range up to 110 mm, it is possible to install multilayer system configurations never attempted before.

The material chosen for Pexal XL is PPSU. This is a technopolymer with exceptional mechanical and corrosion resistance, making it ideal for water supply, heating, cooling and industrial installations.

Therefore, the points of excellence of this system are its safety and modular structure.
Additionally, thanks to its easy, quick, and intuitive installation process, it provides value not only in terms of technology but also productivity and efficiency on the job site.

The Pexal XL® Difference.

The New Modular Technopolymer Fittings:

Safety

Pexal® XL fittings are made with a special hose barb using a profile with two seals to ensure maximum safety and

reliability over time. The system is completed by PPS collars, ensuring mechanical strength and system uniformity.

Hygienic Properties

Pexal® XL press fittings are certified for drinking water supply, therefore they can be used for domestic hot and cold water distribution systems. The material of these fittings ensures an outstanding level of hygiene, as well as an excellent resistance to the treatments against legionella.

Chemical Resistance

The polyphenylsulfone (PPSU) is a technopolymer featuring excellent resistance to oxidation, corrosion, and to the main chemical components dissolved in water, cement and lime.

Reduced pressure loss

The closure with collar allows the prefabrication of fittings directly on the counter resulting in great simplification of the assembly procedures, in case of installation at height, and a significant accident risk reduction

Barrier against oxygen and light

Pexal® XL is a simple and user- friendly system. The assembly of modules requires no special equipment, as sealing collars are closed manually. Moreover, the technopolymer lightweight is a further advantage.

Logistics

The modularity of Pexal® XL is a benefit also for logistics: the possibility of creating all the necessary set-ups with a reduced number of items, allows maximum efficiency even in case of little storage available.

Modularity

Pexal® XL modular philosophy ensures extreme installation flexibility while using just a few items. The assembly versatility allows wide system design freedom, and easily remedying the unforeseen events at the site.

Polyphenylsulfone

Pexal XL is made of Polyphenylsulfone (PPSU)a technopolymer that provides exceptional mechanical performance, used mainly in automotive applications, in the aerospace and medical industry, and which in recent years is now widely used in the plumbing industry.

This material stands out for its excellent mechanical resistance even at high temperatures and its resistance to the main chemical compounds. The mechanical characteristics such as tensile strength, modulus of elasticity and ageing resistance far exceeds those of normal polymers.

Characteristics

The Pexal XL® line of fittings combines the exceptional mechanical characteristics of polyphenylsulfone with the advantages of a pressed joint with stainless steel sleeve.

Just like the brass press fittings, & Bravopress® line, Pexal XL was designed to reduce installation times by using a portable pressing machine equipped with specific pressing jaws.

The insert of these fittings, equipped with two O-rings is characterised by a special profile which, in the event of a non-pressed fitting, allows the immediate identification of the leakage by dripping during pressure testing of the system.
