Vacuum Breakers

  • Protects piping & systems associated with HTST process
  • Robust & simple to CIP
  • Cost-effective way to meet stringent sanitary standards
  • Compact, fast-acting & fully automated

Protect pasteurization piping and systems from vacuum conditions with vacuum breakers from Rodem and our manufacturing partners.


The Alfa Laval Unique Vacuum Breaker Valve is a pneumatic check valve that stops vacuum conditions in high-temperature, short-time (HTST) pasteurization systems. Effortlessly configured to fit nearly any requirement, this robust easy-to-clean-in-place valve is a cost-effective way to meet high standards of hygiene and aseptic compatibility across the dairy, food and beverage segment.


Protect Your Process


  • Designed for convenient and effective CIP
  • Compact, fast-acting and fully automated valve
  • Exceptional valve hygiene and cleanability
  • Authorized to carry the 3-A symbol


The Unique Vacuum Breaker Valve delivers safe, efficient and cost-effective operation of HTST pasteurization piping and systems by preventing vacuum during all phases of production.


Built on a established modular platform of the Unique SSSV small single seat valve, it is easy to select, easy to operate and easy to clean, requiring only a single air connection for Cleaning-in-Place (CIP) capabilities. It can also be fitted with the Alfa Laval ThinkTop® V50 for sensing and control of the valve.


Design & Use


The Unique Vacuum Breaker Valve is made up of stainless steel valve body, seals, actuator, an internal ball that moves up and down inside the valve chamber, and clamp rings and operated similarly to a ball check valve. When pipelines are pressurized during a process or CIP, the internal ball is forced upward against its seat and closes the vent port. When pipeline pressure drops, the ball is drawn down, permitting air to enter the vent, thereby preventing vacuum in the system.


During CIP, a pneumatic actuator is used (pulsed) to force the ball off the upper seat, enabling the seat and the interior of the vacuum breaker valve to be cleaned. CIP fluid is discharged during the actuator pulse and is drained through the vent port.
