Alfa Laval’s Unique SSV tangential valves for use in tank openings, horizontally mounted drains and for wherever space restriction make it difficult to install valves at other angles.
The Alfa Laval Unique SSV Tangential 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 demands in terms of hygiene and safety.
Build on the well proven Unique SSV platform, it provides complete drainability of the valve body near tank openings, on horizontally mounted ports, or wherever space restrictions, make it difficult to install valves at other angles.
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.
Application
The Unique SSV Tangential is designed to provide complete drainability of the valve body when space is limited in hygienic applications across the dairy, food and beverage, brewery and a variety of other industries.
Standard Design
The Unique SSV Tangential is available in a one- or two-body configuration, with easy-to-configure valve bodies, plugs, actuator and clamp rings. The valve can be configured as a shut-off valve with two or three ports or as a changeover valve with three to five ports.
To ensure flexibility, the valve seat that sits between the two bodies in the changeover version is provided for assembly. The valve seals are optimized for durability and long service life through a defined compression design. The actuator is connected to the valve body using a yoke, and all components are assembled with clamp rings.
The valve can also be fitted with the Alfa Laval ThinkTop V50 and V70 for sensing and control of the valve. Using the Alfa Laval Anytime configurator, it is easy to customize to meet virtually any process requirement.
Options
- Fully maintainable actuator.
- High-pressure actuator.
- Product wetted seals in HBNR or FPM.
- TR2 plug seal in PTFE for special applications.
- Valve sensing and control devices, inlu. ThinkTop, ThinkTop Basic and IndiTop
- Fittings in accordance with required standard.
- External surface finish 3-A bright.
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.
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, this ensuring production safety. The enhanced performance of the actuator makes operation safer and more efficient.
Exceptional valve hygiene
To ensure high sealing quality, the Unique SSV is engineered to provide excellent hygiene and cleanability. With a surface that has a fine finish, 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.
Greater value durability
To ensure high sealing quality, the Unique SSV range features defined compression of the O-rings with a metal-to-metal contact between plug and seat. 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 port 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.
Working Principle
The Alfa Laval Unique SSV Tangential is operated by means of compressed air from a remote location. The actuator smooths operation and protects process lines against pressure perks, while directing or diverting fluids. The valve can be controlled using an Alfa Laval ThinkTop®. The valve generally has two working ports for air supply in and for process air supply; for changeover valves, a third port is required.
