Unique SSV Tangential

The Alfa Laval Unique SSV Tangential pneumatic single seat valve is versatile and dependable, with only one point of contact between the plug and the seat, lowering the risk of contamination. Its hygienic, versatile and space-saving design meets the strictest process safety and cleanliness requirements.

Constructed on the tried and true Unique SSV basis, it allows the entire valve body to drain when fitted near tank openings, on horizontally positioned ports, or in other situations where there is insufficient space to install the valves at other angles. The minimal moving parts assure ease of maintenance, high reliability and a low total cost of ownership. Its comprehensive range of supplementary features allows it to be adapted to the needs of certain procedures. When floor space is limited in sanitary environments such as the food, beverage, dairy and brewing industries, this one of a kind SSV Tangential provides full body drainability.

Application

When space is restricted in sanitary applications throughout the dairy, food, beverage, brewing, and many other industries, this unique SSV tangential is made to provide complete drainability of the valve body.

Benefit

1. Superior cleanability
2. Smooth inner valve body free of cracks
3. Longer seal life because of the defined seal compression
4. Improved product safety because of the static seal leak detection
5. Protection against full vacuum because of the double lip seal

Standard Design

With its user-friendly valve bodies, plugs, actuator, and clamp rings, the Unique SSV Tangential valve is offered in either a one- or two-body configuration. Two or three ports allow the valve to function as a shut-off valve, while three to five ports allow it to function as a changeover valve.

The valve seat, which is assembled between the two bodies in the changeover version, is supplied to ensure flexibility. The valve seals’ predetermined compression design maximizes their durability and service life. Clamp rings secure the actuator to the valve body, and a yoke connects the two. For additional sensing and control options, the Alfa Laval ThinkTop V50 and V70 can be attached to the valve. The Alfa Laval Anytime configurator makes it simple to tailor to almost any process need.

Working Principle

Compressed air is used to operate the Alfa Laval Unique SSV Tangential from a distant place. By guiding or diverting fluids, the actuator makes operations more smooth and prevents pressure peaks in process lines. An Alfa Laval ThinkTop can be used to control the valve.
