Valves - Flow Management:
From revolutionary advances like weld-free construction to fine enhancements that reduce fluid and energy consumption, Alfa Laval has led the way in hygienic valve development. Our valve portfolio today offers a strong mix of security and simplicity.
A Seal of Quality:
In their role as flow directors and necessary safeguards, valves are of critical importance to any hygienic process. Even small differences in their operation make a major difference, especially when they are used together in large numbers.
As the market leader in valves and valve clusters for hygienic industries, Alfa Laval has an uncompromising commitment to valve quality. Over the years, our dedicated research and development team has not only optimized valve function, but also improved valve economy by simplifying construction, cleaning and maintenance.
In addition to seat valves in single-seat and double-seat models, our broad valve portfolio comprises diaphragm valves, butterfly valves, ball valves, check valves, regulating valves and sampling valves. Furthermore, we offer special valves intended for specific purposes, including a growing portfolio of valves for biopharm use. Because each aspect of these valves has been carefully thought through, each valve is assured to deliver optimal performance and a maximum amount of uptime.
Perhaps the clearest hallmark of Alfa Laval valves is their astonishing simplicity. The valve bodies in our Unique single-seat series, for instance, are created from a single disc of stainless steel and possess no welds where bacteria can accumulate.
In fact, all valves from Alfa Laval are constructed with a minimal number of elements. This means fewer moving parts to break or malfunction, but it also means far easier maintenance. In contrast to 30 or 40 steps, a valve from Alfa Laval can be disassembled in as few as 10.
Furthermore, our valves are designed without loose springs, which means they pose no safety risk when the valve body is opened.
Built to Adapt:
Additional simplicity is created by modular valve design, which is specific to Alfa Laval and can be found throughout most of our valve portfolio. Our Unique mix proof and single-seat valves, for example, are constructed from a series of base parts that allow valves to be configured for different application requirements. This enables quick changeovers between standard and aseptic milk production, for example, or a move from juice to juice concentrate. By keeping the valve body but exchanging stems, actuators and other elements, conversions can be made in just a few minutes per valve without removing the valve body from the system.
Of course, modularity has advantages beyond construction and conversion. Because modular thinking allows features to be chosen as needed, it also does away with unnecessary frills and provides a quicker return on investment.
Strengths Great and Small:
While creating modular systems requires a good deal of overview, Alfa Laval also puts considerable effort into valve details. This includes the development of gasket compounds for greater strength and resilience, as well as the use of surface finishes that combine good appearance with maximum hygiene and cleanability.
In addition, we look for every way possible to limit the consumption of resources and energy. By reducing the fluid required for CIP, for example, we decrease the associated needs for both heating and pumping.
While the results may seem negligible when looking at a single valve, the combined effect of all valves in an installation can amount to significant savings and reduced environmental impact.
