Derivation clamp for multilayer systems.

connex-t

Connex-T is truly a revolution in the installation of multilayer systems. Developed by Valsir to create derivations on new or existing multilayer pipes with large diameters, it provides significant reductions in installation time and costs and facilitates maintenance work.

The solutions adopted have been studied so that margins of error are minimised and installation is facilitated: it is not always easy to intervene on existing pipelines due to the position and the limited space in which the job needs to be performed.

The particular profile of the connection with the pipe has been designed and engineered specifically to reduce pressure loss to a minimum.

Tested in accordance with the strictest international standards on multilayer systems and subject to the most rigid quality tests in Valsir, Connex-T has a guaranteed durability of at least 50 years in full observance of the standards; in this period a use at pressures of 10 bar and at temperatures up to 95°C is allowed.


The characteristics of the Connex-t clamp

Fast and easy installation

in every situation on existing pipelines.

Installable on existing Valsir multilayer pipes

On existing Valsir multilayer pipes Connex-T allows a derivation to be created with a significant reduction in costs as far as the material used and labour costs are concerned. In conventional systems, in order to create a derivation, quite a long piece of pipe needs to be cut and 2 fittings must be inserted. Connex-T can be installed without cutting the pipe and without fittings.

Body in technopolymer

with exceptional characteristics of mechanical resistance.

Special profiles that prevent screws loosening

The screw holes have special profiles that prevent screws loosening during installation.

Durability guaranteed for 50 years

when used at pressures of 10 bar and temperatures as high as 95°C.

Significantly reduced pressure loss

as compared with a conventional T fitting. Connex-T does not reduce the pipe bore section and the special profile of the insert minimises pressure loss.

Locknuts are incorporated in the rear half-shell

to simplify screws tightening. The housing where they are inserted is designed to avoid screws loosening during installation and to guarantee a greater tightening torque.

Quality test

Tested according to the strictest international standards on multilayer systems (DVGW W542, DVGW W534, EN ISO 21003 -2 -3 and -5).

The blocking nut of the threaded insert

is provided with an end-of-stroke lock system that avoids elevated tightening forces that would damage the multilayer pipe.

clasps placed on the sides to block the two parts keep the two pieces

the clasps placed on the sides to block the two parts keep the two pieces in place during assembly and prevent them from falling during the installation phase.

Wide range of diameters

Wide range of diameters from 50 mm Ø to 90 mm Ø with available derivations from ½” up to 1”.

Non-toxic materials

The system is composed of completely non-toxic materials certified to transport food liquids and drinking water.

Ecosostenibilità pexal

Recyclable materials

Connex-T are produced with materials that can be completely recycled, which, at the end of their service life can be recovered. The production processes used are energy efficient and are of a low environmental impact; in terms of the environment and conservation of resources, Pexal® and Mixal® are in line with Green Building principles.

Connex-T Installation in 6 steps

 

Step 1

Use the centring hole placed in the rear half-shell to create the guide hole (use a 6 mm Ø drill bit for metal).

 

Step 2

Create the hole through an appropriate hollow cutter using the centring hole as a guide for the cutting tip. While drilling, keep the drill perpendicular to the pipe axis.

 

Step 3

Remove any cutting burrs and sharp edges inside the hole using the fine sandpaper provided. Clean the hole in order to eliminate any residue on the edge and inside the hole.

 

Step 4

Put the threaded insert and the front half-shell inside the hole, positioning it over the pipe. Turn the blocking nut by hand in order to secure the half-shell to the pipe.

 

Step 5

Place the rear half-shell and secure it to the front shell using the special fastening clasps, in this way the two parts will remain attached to the pipe. Tighten using the provided screws with a 6 mm Ø socket wrench or a screwdriver.

 

Step 6

Fully Turn the locking nut on the threaded insert until end-of-stroke.


The details that make the difference

A number of innovative solutions have been designed for Connex-T to reduce installation time

and eliminate margins of error in order to help the plumber that must often work in tight spaces.

 

Blocking nut with end-of-stroke system

The threaded insert blocking nut has been designed for an easy and safe installation. It is provided with an end-of-stroke lock system that avoids elevated tightening forces that would damage the multilayer pipe.



 

Blocking system of the half-shells

Special clasps placed on the half-shells allow the two parts of the Connex-T to be blocked before they are fully tightened with the screws, thus preventing the two pieces from disconnecting and falling on the ground. 

 

Anti-loosening system of the screws

Special profiles have been created in the holes where the screws are inserted to avoid them loosening during installation. The screw head allows the use of both socket wrenches and screwdrivers for tightening.

  

 

Locknuts incorporated

Locknuts are incorporated in the rear half-shell thus guaranteeing improved screws tightening. The housing where they are inserted is designed to avoid screws loosening during installation and to guarantee a greater tightening torque.
