Alfa Laval’s Unique SSV reverse-acting valve for use in applications where the flow direction does not allow the use of a standard Unique SSV valve to eliminate the risk of pressure shock.
The Alfa Laval Unique SSV Reverse Acting 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. Built on the well-proven Alfa Laval Unique SSV platform, it provides multiple solutions where the direction of the flow does not allow the use of a standard Alfa Laval Unique SSV to eliminate the risk of pressure shock.
Few moving parts ensure easy dismantling, high reliability and low maintenance costs. A wide range of optional features enables customization to specific process requirements.
Application
The Unique SSV Reverse Acting is designed for use in a broad range of hygienic applications across the dairy, food and beverage, brewery and many other industries.
Standard Design
The Unique SSV Reverse Acting is available in a two- or three-body configuration, with easy-to-configure valve bodies, plugs, actuators and clamp rings. The valve can be configured as a shut-off valve with two or four working ports as a changeover valve with three to six ports.
To ensure flexibility, the valve seat that sits between the two bodies in both the shut-off and 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, incl. 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 (SSV) 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. Alfa Laval’s Selection 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.
Exceptional valve hygiene
The Unique SSV range is engineered to provide excellent hygiene and cleanability. With a surface finish that is fine, the smooth, weld-free valve body eliminates crevices that can trap bacteria. The design of the plugs 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 fully traceability in compliance with the EU Food Regulation 1935/2004.
Greater valve durability
To ensure high sealing quality, the Unique SSV range provides long service life, reduced product loss, greater product safety and more processing uptime. Few moving parts, 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.
Working principle
The Alfa Laval Unique SSV Reverse Acting is operated by means of compressed air from a remote location. The actuator smooths operation and protects process lines against pressure peaks. The valve can be controlled by using and 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.
