Unique SSV Aseptic
The Alfa Laval Unique SSV Aseptic is a versatile, reliable pneumatic single seat valve with a single contact surface between the plug and the seat to minimize the risk of contamination. Its compact, modular and hygienic design meets the highest process requirements in terms of hygiene and safety.
Versatile and purpose-built manual and pneumatic valves with a single plug design.
- Durable, aseptic valve design
- Superior cleanability – smooth inner valve body without crevices
- Extended seal life due to the defined seal compression
- Enhanced product safety due to the static seal leak detection
- Protection against bacterial contamination
Built on the well-proven Alfa Laval Unique SSV platform, the Unique SSV Aseptic features a one-piece diaphragm that provides hermetic sealing to prevent intrusion of contaminants from the atmosphere, ensuring full protection against the effects of microorganisms during processing. The special diaphragm can also be used with the Unique SSV Standard, Tangential, Two Step, Manual and Tank Outlet. Few moving parts ensure easy maintenance, high reliability and low total cost of ownership. A wide range of optional features enables customization to specific process requirements. This Unique SSV Aseptic is designed for uninterrupted production in sterile and aseptic applications across the dairy, food, beverage, brewery, biotechnology, pharmaceutical and many other industries.
How does the Unique SSV Aseptic valve work
Unique SSV Aseptic
Fully modular with the proven design of the Unique SSV the aseptic single seat valve is equipped with a hermetic sealing diaphragm that ensures true aseptic conditions during operation. It hermetically seals against intrusion from the atmosphere and ensures full protection against the effects of microorganisms.
With a “sandwich construction” of PTFE on the product side, EPDM and an enforcing mesh, the aseptic diaphragm is optimized to guarantee reliable performance and long lifetime. In open position the one-piece diaphragm is mechanically supported by the valve to reduce wear and increase endurance.
The Alfa Laval Aseptic valve is available in both pneumatic and manual configurations.

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.
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.
Operating principle
The Alfa Laval Unique SSV is an air-operated seat valve that is remotely operated by means of compressed air. The valve generally has two working ports for air supply in and for process air supply; for changeover valves, a third port is required.

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.
