Unique SSV aseptique
Unique SSV aseptic valve for sterile process applications. A one-piece diaphragm provides hermetic sealing against intrusion from the atmosphere, ensuring full protection against the effects of microorganisms during processing. The special diaphragm offers modularity as it can be used with a broad range of the Unique SSV configurations – including standard, tangential, two-step, manual and tank outlet valves.
Versatile and reliable single seat valve
Alfa Laval Unique single seat valves (SSVs) are robust and reliable pneumatic seat valves that are supremely reliable and versatile.
Modularity provides cost-effective and nearly endless possibilities for purpose-built seat valves that meet high standards of hygiene and aseptic compatibility. Configure the Unique SSV valve bodies, plugs and actuators to meet virtually any requirement.
Our Selection Guide illustrates the many combinations of features and types available with the Unique SSV valve range.
In the US and Canada the Unique 7000 corresponds to the Unique single seat valve.
Superior valve process safety
The Unique SSV range is built on a proven modular platform used on more than a million valves in service worldwide. Pressed from a single stainless steel disc, the valve body is extremely strong and durable, thus ensuring production safety. The enhanced performance of the actuator makes operation safer and more efficient.
Exceptional valve hygiene
The Unique SSV range is engineered to provide excellent hygiene and cleanability. With a surface finish of Ra ≤ 0.8μm, the smooth, weld-free valve body eliminates crevices that can trap bacteria. The design of the plug supports enhanced cleaning-in-place capabilities, and a double-acting lip seal that minimizes any risk of cross-contamination.
Alfa Laval Unique SSV valves meet most hygienic standards requested in the dairy, food and beverage, and personal care industries. The Unique SSV range is EHEDG-certified and authorized to carry the 3-A symbol. The range also provides full traceability in compliance with the EU Food Regulation 1935/2004.
Please refer to Documentation for more information.
Greater valve durability
To ensure high sealing quality, the Unique SSV range features defined compression of the O-rings with metal-to-metal contact between plug and seat. This significantly reduces wear and extends valve service life. The standard Unique SSV is supplied with a semi-maintainable actuator that has a five-year warranty.
Low total cost of ownership
Thanks to its straightforward, reliable design, the Unique SSV range provides long service life, reduced product loss, greater product safety and more processing uptime. Few moving parts reduce service requirements and inventory costs. More effective CIP procedures with reduced cleaning cycles and, subsequently, the reduced use of cleaning fluids, water and utilities also contribute to the Unique SSV’s low total cost of ownership.
Construction
The Alfa Laval Unique SSV range consists of one, two or three valve bodies, plug, sealing, actuator and clamp ring.

Fonctionnement
Principe de fonctionnement
L'Alfa Laval Unique SSV est une vanne à clapet à commande pneumatique, contrôlée à distance avec de l'air comprimé. La vanne possède généralement deux orifices de fonctionnement, pour l'alimentation en air et pour l'arrivée d'air de traitement. Sur les vannes d'inversion, un troisième orifice est requis.

Unique SSV aseptique
Entièrement modulaire avec la conception éprouvée Unique SSV, la vanne à clapet simple aseptique est équipée d'une membrane d'étanchéité hermétique qui garantit de véritables conditions aseptiques pendant le fonctionnement. Elle assure une étanchéité hermétique contre les intrusions venant de l'atmosphère et garantit ainsi une protection totale contre les effets des micro-organismes.
Avec une « construction en sandwich » en PTFE côté produit, en EPDM et un maillage de renforcement, la membrane aseptique est optimisée pour garantir des performances fiables et une longue durée de vie. En position ouverte, la membrane d'une seule pièce est supportée mécaniquement par la vanne pour réduire l'usure et augmenter l'endurance.
La vanne Unique SSV aseptique est disponible en configuration pneumatique et manuelle.
