Looking ahead, today: the new W830 range

The “W” in W830: Water, Compatibility, and European Standards

The “W” code is no coincidence: the initial letter “W” comes from Water and clearly identifies the range as designed for potable water distribution.

This choice highlights two key points:

• Already compliant materials – All CW724R brass used in this range is compatible with the positive lists of the European Drinking Water Directive (DWD), ensuring safety in water systems.
• Suitability for drinking water – The valves can come into contact with water without health risks, anticipating future requirements and providing continuity and reliability in installations.

In this way, Giacomini pursues a forward-looking design logic: the “W” is not just a code, it represents a concept of safety and compliance integrated into the range.

A valve designed for the new European Drinking Water Directive

The W831TH series is made of low-lead CW724R brass (Pb ≤ 0.1%), a material already included in the positive lists defined by the European Drinking Water Directive.

In this context, Giacomini chose not to wait for regulatory obligations but to immediately develop a range compliant with future requirements, protecting designers, installers, and commercial partners while ensuring continuity of investment.

Technical performance and reliability

Beyond regulatory compliance, the W831TH range offers high-level technical features:

• Ball valve specifically for drinking water
• Full port design to maximize flow
• Body and ends in low-lead CW724R brass
• DZR material resistant to dezincification
• Operating temperature: 5–110 °C (up to 120 °C for short periods)
• Maximum pressure up to 35 bar (depending on size)
• Extended butterfly handle for pipes with thick insulation

The range covers multiple sizes (from 1/2” to 2”), providing a complete solution for potable water distribution systems.

Lead-free materials: a technical and strategic choice

The transition to ultra-low lead brass is not only a response to legislative requirements.
It is a choice aligned with Giacomini’s sustainability path, aiming to:

• Ensure greater safety of materials in contact with drinking water
• Innovate products responsibly
• Reduce environmental impact along the supply chain
• Anticipate future European regulatory requirements

The W831TH range is fully integrated into the 2026–2028 Sustainability Strategic Plan, with measurable objectives and a structured roadmap. Innovating in materials means protecting people’s health and contributing to the quality of water resources.

Anticipating the market, creating value

In a context where European certifications for drinking water are becoming increasingly widespread, designing already according to criteria compatible with future regulations represents a tangible competitive advantage.

With the creation of the “W” code, Giacomini has taken a forward-looking step: building today a range ready for future requirements, compatible with positive lists and suitable for use with potable water.

Choosing this range means:

• Reducing the risk of future adjustments
• Ensuring design continuity
• Guaranteeing medium- to long-term compliance
• Adding sustainable value to investments

At Giacomini, innovation means anticipating the regulation, not chasing it.

Building the future of water, together

The quality of drinking water is a shared responsibility.
Designing safe, certifiable, and sustainable components is an integral part of our industrial commitment.

Giacomini takes a concrete step toward the future of water distribution in Europe.
Because foresight is not just vision: it’s action.
