Vacuum breaker in complete stainless steel construction. It is best suited on steam inlets to heat exchangers, jacketed kettles, liquid process lines, chilled water lines, boiler feed water lines and air coils, to admit air whenever vacuum condition is developed in the system.
Works like a check valve and allows air to enter the steam or liquid system, however, steam or liquid escape is shut off. Vacuum breaker is designed to allow air into condensing steam or liquid systems where creation of a vacuum would inhibit liquid drainage and decrease system performance and efficiency
- System connection: DN15
- Air inlet connection: DN8, 10, 15
Vacuum breaker should be installed in a vertical position with the cap at top and should be placed at the highest point in the system. An isolation valve should be fitted prior to vacuum breaker to facilitate servicing.
- Easy to operate
- Sight glass is maintenance free
- Very cheap
- Used to check flow of fluid easily.
After the vacuum breaker is isolated from the system, unscrew the top cap & examine for any wear/tear & debris on ball or seat and valve which could cause breakage of system pressure. Clean and refit. With the exception of possible cleaning, this device is maintenance-free. Vacuum breakers are not repairable on-line.
