Description

Alfa Laval Unique Vacuum Breaker Valve

The Alfa Laval Unique Vacuum Breaker Valve is a high-performance pneumatic check valve engineered to prevent vacuum conditions in high-temperature short-time (HTST) pasteurization systems. This hygienic, clean-in-place (CIP) capable vacuum breaker valve helps maintain positive pressure, protecting pipelines and processing equipment from vacuum-related damage. Built on the trusted Alfa Laval Unique SSSV platform, this Alfa Laval vacuum valve offers reliable, automated performance for sanitary applications in the dairy, food and beverage industries.

How does Unique Vacuum Breaker Valve work?

Functioning as a control check valve, the Alfa Laval Unique Vacuum Breaker Valve operates similarly to a ball check mechanism. During processing or CIP, when the system is pressurized, the internal ball is pushed upward against its seat, effectively sealing the vent port. If the pressure drops and a vacuum condition begins to form, the ball descends, opening the vent and allowing air to enter, thereby preventing vacuum formation. For cleaning, the pneumatic check valve actuator can be pulsed to dislodge the ball from the seat. This allows CIP fluid to flush the valve chamber and exit through the vent port, ensuring the internal surfaces remain hygienic and contamination-free.

FAQ

What is a vacuum breaker valve for HTST pasteurization?
A Alfa Laval vacuum breaker valve for HTST (High-Temperature Short-Time) pasteurization is used to prevent vacuum conditions that could disrupt the pasteurization process, ensuring product quality and safety.

What is the function of a pneumatic check valve in vacuum protection?
A pneumatic check valve like the Alfa Laval Unique Vacuum Breaker Valve automatically responds to changes in system pressure. When a vacuum begins to form, the internal actuator and ball mechanism allow air in, preventing damage caused by negative pressure. This makes it an essential component in CIP capable and hygienic process lines.

What makes the vacuum breaker valve suitable for food and beverage applications?
The unique vacuum breaker valve is constructed with a stainless steel body, fast-acting actuator, and hygienic sealing. Designed for sanitary applications, it ensures clean processing in industries such as dairy, food, and beverages, and it is certified to carry the 3-A symbol.
