Alfa Laval Unique SSV Aseptic Manually Operated Valve

Alfa Laval Unique SSV Aseptic Manually Operated Valve

The Alfa Laval Unique SSV Aseptic Manually Operated is a high-performance aseptic single seat valve designed to meet the rigorous hygiene demands of sterile process applications. By utilizing a single contact surface between the plug and the seat, this valve minimizes the risk of product contamination. At the core of its design is a one-piece diaphragm that provides a hermetic seal against the atmosphere, ensuring full protection against microorganisms. This manual hygienic valve offers a simple, reliable solution for operators who require precise control without the complexity of automated systems, all while maintaining the integrity of sensitive process media in regulated industries.

Engineering aseptic security with hermetic sealing

The aseptic single seat valve is built upon the globally proven Unique SSV platform, specifically engineered to eliminate the intrusion of atmospheric contaminants. The standout feature is the one-piece PTFE-faced diaphragm. This component creates a hermetic seal that separates the process medium from the environment, making it an essential tool for sterile production. Because the design is modular, the same high-standard diaphragm technology can be applied across tangential, two-step, and tank outlet configurations, ensuring consistency across your entire fluid handling system.

How defined compression extends seal life

Maintenance efficiency is a primary concern for process engineers. The Unique SSV Aseptic addresses this through optimized valve seals featuring a defined compression design. This engineering approach ensures that elastomers are not over-compressed during operation, significantly extending seal life and reducing the frequency of service intervals. The crevice-free, smooth inner valve body further enhances cleanability during CIP and SIP cycles, preventing the bioburden buildup typical of lesser manual valves.

Modular architecture for process flexibility

The valve is available in one- or two-body configurations, allowing for seamless integration as a shut-off valve with two or three ports, or a change-over valve with up to five ports. This flexibility is supported by the Alfa Laval Anytime configurator, enabling technical distributors to provide specific valve plugs and clamp rings tailored to unique system geometries. Whether you are managing simple fluid transfer or complex tank outlet requirements, the 1.4404 (AISI 316L) construction ensures compatibility with aggressive cleaning agents and high-temperature sterilization.

FAQ

Euroflow serves customers across southern and central Germany — covering postal code areas 66–99 and 07–08, spanning Baden-Württemberg, Bavaria, Saarland, Rhineland-Palatinate, Hesse, Thuringia, and Saxony. As an Alfa Laval Master Distributor for tank manufacturers, plant engineers, system suppliers, and end customers, we provide expert support in selecting and designing systems for viscous product handling and cleaning applications.

The valve uses a one-piece PTFE/EPDM diaphragm that creates a physical barrier between the process media and the atmosphere. This eliminates the risk of airborne microorganisms or contaminants entering the system through the valve stem area, which is critical for sterile processing.

Yes, while the operation is manual, the valve design allows for the installation of Alfa Laval ThinkTop V50 and V70 units. These sensing units provide real-time feedback on valve position to your control system, enhancing process transparency.

The standard EPDM gaskets and PTFE-faced diaphragm are designed to withstand flush housing sterilization up to 150°C (380 kPa / 3.8 bar) for durations of less than one minute during SIP cycles.
