Expanding a product range is not about adding new references to a catalogue. It is about responding to real conditions on site. The introduction of this new ball valve for multilayer systems strengthens the adaptability of the MT range across different installation scenarios.
What Ball Valves with Compression Connection for Multilayer Pipe Are
In many multilayer system installations, pressing tools are not always available. Ball valves with compression connections for multilayer pipe provide a reliable technical alternative, integrating a mechanical tightening system within a robust design engineered to ensure tightness and long term durability.
Specifically Designed for Multilayer Systems
This new series has been designed and tested in accordance with UNE EN ISO 21003, the standard applicable to multilayer piping systems for water installations. The valves are manufactured from CW617N brass in compliance with UNE EN 12165, featuring a reinforced body and internal components engineered to guarantee long term tightness and durability.
The compression connection incorporates a brass compression ring, a tightening nut also made of CW617N brass and double EPDM O rings certified to Kiwa Class III, ensuring reliable sealing at the most critical point of the system: the pipe to valve connection.
The result is a robust valve suitable for both hot and cold potable water installations, as well as compressed air systems.
Key Technical Features of the New Range
Certified materials, precise dimensional control and stable performance under pressure and temperature define these ball valves with compression connection for multilayer pipe, fully aligned with MT technical standards.
Materials and Components Focused on Reliability
The body and ball are manufactured from CW617N brass. The seats are made of PTFE, a material known for its low friction and excellent resistance to repeated opening and closing cycles. The stem incorporates NBR seals certified to KTW standards, while the sealing system is reinforced by double EPDM O rings certified to Kiwa Class III at the multilayer connection.
In addition, the valves include a nylon anti electrolysis ring, a technical feature designed to reduce potential risks associated with galvanic currents in certain installations.
The maximum working temperature reaches 95 degrees Celsius at 10 bar, comfortably meeting the typical demands of domestic hot water networks. Actuation is provided either by an ergonomic steel handle with high protection anti corrosion coating, designed for secure grip and resistance in humid or demanding environments, or by an aluminium butterfly handle depending on the model.
Each component responds to a clear objective: mechanical stability, long lasting tightness and predictable performance over time.
Compatibility with Multilayer Pipe and Typical Applications
Designed to integrate into standard configurations without complex adaptations, these ball valves with compression connection for multilayer pipe allow direct installation within the most common systems, maintaining dimensional consistency and connection security.
Diameters and Application Environments
The range is compatible with multilayer pipe in Ø16×2 and Ø20×2 dimensions, two of the most widely used sizes in plumbing installations.
This allows direct integration into residential internal distribution networks, technical rooms, water based HVAC installations and small industrial circuits. The toothed connector profile with an optimised chamfer facilitates pipe insertion and improves fitting accuracy during installation.
For installers, this compatibility reduces uncertainty on site. For specifiers, it provides confidence in working with a solution aligned with current market standards. For distributors, it simplifies stock management by covering high rotation sizes.
Differences Compared to Press Connection Multilayer Valves
With the introduction of the new compression connection multilayer valves, MT expands its technical offering.
Press or Compression: When to Choose Each System
Press connection provides speed and consistency in serial installations where dedicated tools are available. It is a well established solution in new build projects and large scale developments.
Compression connection, on the other hand, offers a key advantage: independence from pressing tools. In refurbishment works, maintenance operations, small interventions or environments where electric or heavy equipment is not available, this solution enables secure installation with controlled manual tightening.
The objective is not to position one system against the other, but to provide alternatives. With this extension of the range, MT covers different installation needs and working environments while maintaining equivalent quality and certification standards in both systems.
Added Value for Installers, Specifiers and Distributors
Ball valves with compression connection for multilayer pipe do more than expand the catalogue. They add operational flexibility and strengthen the technical proposition for those who work with them.
Greater On Site Flexibility, Same Technical Assurance
For installers, having access to both technologies, press and compression, means being able to decide according to actual site conditions. Greater installation flexibility reduces dependency on specific tools and improves responsiveness to unforeseen situations.
For specifiers, selecting a valve designed and tested according to UNE EN ISO 21003, with KTW and Kiwa certified materials, simplifies technical definition and regulatory compliance within the project.
For distributors, adding this reference broadens the coverage of the multilayer range and responds to customers who require immediate, reliable solutions without the need for additional equipment.
A Range Extension Aligned with Real Installation Needs
At MT, products are not conceived as isolated components. Each new addition forms part of a broader strategy: delivering complete, technically supported solutions designed for professionals who require clear and dependable answers. The new ball valve with compression connection for multilayer pipe is another step in that direction. More options, the same technical standards and the support of a team that responds efficiently and reliably.
