Unique SSV Reverse Acting
Alfa Laval Unique SSV Reverse Acting is a durable, pneumatic single seat valve specifically designed to prevent pressure shock by reversing the flow direction. Built on the trusted Alfa Laval Unique SSV platform, it has a hygienic and compact construction, featuring a single sealing contact surface between plug and seat to minimize contamination risks. With fewer moving parts, it provides high reliability, lower maintenance costs and simple disassembly, meeting the strict hygienic requirements of the food, beverage, dairy and brewing industries.
Alfa Laval Unique SSV Reverse Acting Applications
Alfa Laval Unique SSV Reverse Acting valve is widely used across industries requiring strict hygienic controls, including:
- Dairy processing: Milk, cheese, yoghurt production.
- Food & beverage: Sauce, fruit juices, liquid food transfer.
- Brewing: Precise fluid management to avoid pressure peaks.
- General hygienic industries: Ideal where product safety and process cleanliness are crucial.
Key Benefits of Alfa Laval Unique SSV Reverse Acting
Superior Hygiene and Easy Cleaning
The valve’s smooth, crevice-free internal surfaces make CIP cleaning efficient, ensuring product purity and eliminating bacterial growth risks.
Extended Seal Life and Durability
Precisely defined seal compression significantly extends seal lifespan, reducing frequent replacements and lowering maintenance costs.
Enhanced Process Safety
Built-in static seal leak detection enhances product safety. The double lip seal feature protects against vacuum conditions, adding another layer of operational reliability.
Flexible Valve Operation
The reverse acting functionality effectively prevents pressure shocks, offering superior protection and flexibility compared to traditional valves.

How the Alfa Laval Unique SSV Reverse Acting Valve Works
The Alfa Laval Unique SSV Reverse Acting valve operates through pneumatic control using compressed air from a remote source. The reverse acting feature ensures smooth actuator operation, reducing the risk of pressure surges in process lines. Actuators, valve bodies, plugs and clamp rings can be configured in various combinations, enabling shut-off or changeover operations with two to six operational ports.
The valve integrates seamlessly with Alfa Laval’s ThinkTop V50 or V70 controllers, allowing precise sensing and valve control. The Alfa Laval Anytime configurator simplifies customizations, making it adaptable to virtually any processing requirement.
