How it works
Construction
The Unique Vacuum Breaker Valve consists of stainless steel valve body, seals, actuator, an internal ball that moves up and down inside the valve chamber, and clamp rings.
Operating principle
The Alfa Laval Unique Vacuum Breaker Valve is operated in a manner similar to that of 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 downward, allowing 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.
