Brass Valves and Fittings: Maximum-Reliability Solutions for Irrigation and Plumbing
At Grupo Almagro, we know that the reliability of an installation depends on the quality of every component. That is why we offer a complete catalogue of brass valves and fittings for demanding professionals. Whether for agricultural irrigation, commercial plumbing or industrial networks, our products guarantee superior performance and exceptional durability. Brass is the experts' choice for its high corrosion resistance and mechanical robustness, ensuring watertight joints even under high pressures.
Our Product Range
Our selection is designed to cover all the technical needs of your projects.
- Ball Valves: Essential for quick, effective flow control, allowing the flow of fluid to be shut off or resumed instantly.
- Check Valves: Indispensable for protecting your installation, these (non-return) valves prevent backflow, allowing the fluid to travel in one direction only. They thus protect equipment such as pumps and meters.
- Gate and Foot Valves: Gate valves are ideal for gradual closure, while foot valves are installed on pump suction lines, combining non-return function with a strainer that prevents solids entering.
- Threaded Fittings and Adaptors: The basis of a leak-free installation. We offer elbows, tees, sleeves and reducers that guarantee a perfect seal.
- Fittings for Polyethylene (PE) Pipe: We use a compression system that ensures a firm, watertight mechanical joint, ideal for potable water service connections and buried irrigation systems.
Applications by Sector
The versatility of brass makes it perfect for a variety of professional sectors.
- Agricultural Irrigation and Landscaping: Its durability is key to withstanding the weather and intensive use.
- Residential and Commercial Plumbing: Brass is the standard for potable water and heating installations thanks to its reliability and hygienic properties.
- Water Supply Networks and Industrial Installations: Our components withstand high pressures and temperatures, minimising maintenance.
Quality Guarantee
Our customers' trust is based on the quality of our products. We distribute only components that meet the highest standards, such as European standard EN 12165 (CW617N alloy). This guarantees maximum corrosion resistance, high mechanical strength to withstand elevated pressures (PN25 or PN30) and safety for contact with potable water. Investing in certified quality reduces the need for costly repairs and replacements in the long term.
Frequently Asked Questions
Here we answer some common questions about these components:
- Why is brass used? For its ideal balance between corrosion resistance, durability and cost.
- How long does a brass valve last? A high-quality one can last between 20 and 30 years, depending on use and water quality.
- What is the difference from bronze? Bronze (copper and tin) is harder, but brass (copper and zinc) offers a better balance between performance and cost for most fresh-water applications.
- What is Nominal Pressure (PN)? It is the maximum working pressure in bar that a component can withstand continuously.
- How do I choose a high-quality ball valve? Look for one manufactured in certified brass such as CW617N, with an internal ball in chrome-plated brass with PTFE seats, and a handle that operates smoothly.
