Unique SSV Two Step Valves
Alfa Laval Unique SSV Two Step Valve
The Alfa Laval Unique SSV Two Step is a versatile, reliable pneumatic Single Seat Valve with a single contact surface between the plug and the seat to minimise 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 is ideal for dosing and two-stage filling to ensure an exact volume or for draining of two pipes at the same time while reducing the risk of pressure shocks. Adjustable lifting height makes it possible to match specific volumes and quantities. A wide range of optional features enables customisation to specific process requirements.

Unique SSV Two Step Valve Key Features
Versatile and Reliable Single Seat Valve
Alfa Laval Unique Single Seat Valves (SSVs) are robust and reliable pneumatic solutions that are supremely 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, thus ensuring production safety. The enhanced performance of the actuator makes operation safer and more efficient.
Exceptional Valve Hygiene
The Unique SSV range provides excellent hygiene and cleanability. A weld-free, Ra ≤ 0.8μm Valve body eliminates bacteria-trapping crevices. The Valve’s design supports enhanced cleaning-in-place, and a double-acting lip seal minimises risk of cross-contamination. Alfa Laval Unique SSV Valves meet hygienic standards in the dairy, food and beverage, and personal care industries. The range is EHEDG-certified, authorised to carry the 3-A symbol, and provides full traceability in compliance with 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 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 range’s low total cost of ownership.
How the Unique SSV Two Step Valve Works
The Alfa Laval Unique SSV Two Step is operated by means of compressed air from a remote location. The actuator smooths operation and an intermediate step protects process lines from pressure peaks while dosing and filling. The Valve can be controlled using an Alfa Laval ThinkTop® V50 or V70 for sensing and control of the Valve.
