Unique SSV

Alfa Laval Unique SSV valves are robust, reliable and versatile pneumatic single seat valves designed for uninterrupted production in a broad range of hygiene-critical applications. Valve bodies, plugs and actuators of these pneumatic control valves can be configured to meet virtually any requirement resulting in cost-effective solutions that meet high hygiene and aseptic compatibility standards.

Designed for ease of maintenance and low cost of ownership

Few moving parts reduce service requirements and inventory costs
Superior cleanability – smooth inner valve body (surface finish of Ra ≤ 0.8μm) eliminates crevices
Extended seal life due to defined seal compression
Static seal leak detection helps ensure product safety
Double lip seal provides protection against bacterial contamination

Tried and tested valve safety: The Unique SSV single seat valve 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. In addition, the enhanced performance of the actuator makes operation safe and efficient.

Exceptional valve hygiene

The Unique SSV range of food grade valves 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 (CIP) capabilities, and a double-acting lip seal that minimizes any risk of cross-contamination.

These single seat 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 of Alfa Laval valves 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, this range of single seat valves 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.

How does the Unique SSV single seat valve work?

Operating principle

The Alfa Laval Unique SSV is an air-operated seat valve, that can be remotely controlled. The valve can be configured as a shut-off or change-over valve with various actuators NO, NC or Two-step for smoother operation to avoid pressure peaks and/or over filling of a tank.

The range of single seat valves has a number of options:

Fully maintainable actuator
High-pressure actuator
Product wetted seals in HNBR or FPM
TR2 plug seal in PTFE for special applications
Valve sensing and control devices, incl. ThinkTop, ThinkTop Basic and IndiTop
Fittings in accordance with required standard
External surface finish 3-A bright
