VB14 Vacuum Breaker
The Spirax Sarco VB14 is a compact brass vacuum breaker for condensing steam and liquid systems. It admits air as equipment cools to prevent vacuum from restricting condensate drainage and operation.

Vacuum breakers are usually selected alongside venting and shutdown behaviour. If the same steam space also needs start-up gas removal or ongoing venting, compare air vents. Where the outlet arrangement also needs quieter atmospheric discharge, continue into blowdown diffusers.
For vessel duties influenced by heat-transfer equipment, this route also connects naturally with steam heat exchangers.
