Alfa Laval’s Unique SSV Y-body valves for use in installations that involve flows with large particles and/or high viscosity, and where the focus is on particularly gentle treatment of products and flows.
The Alfa Laval’s Unique SSV Y-body 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, the Unique SSV Y-body provides uninterrupted flow and gentle handling of products that are highly viscous or contain large particles and require gentle product treatment.
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
This robust single seat valve is designed for uninterrupted flow and gentle handling of products that are highly viscous or contain large particles in hygienic applications across the dairy, food and beverage, brewery and many other industries.
Standard Designs
The Unique SSV Y-Body is available in a one-body configuration, with easy-to-configure valve bodies, plugs, actuator and clamp ring.
The valve seals are optimized for durability and long-service life through a defined compression. The actuator is connected to the valve body using a yoke and all components are assembled with a clamp ring.
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 makes it 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 (SSVs) are robust and reliable pneumatic seat valves that are 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 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 fine surface 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 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 the 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.
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 process air supply; for changeover valves, a third port is required. The valve can be controlled by using an Alfa Laval ThinkTop®.
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 Unique SSV Aseptic valve is available in both pneumatic and manual configurations.
