The WVBSS Vacuum Breaker is used on heat exchangers, air coils, jacketed kettles, pressing machines, boiler feed water tanks, sparge systems, water lines, or anywhere else an unwanted vacuum may occur. The WVBSS allows air to enter the steam or liquid system in order to “break the vacuum” caused by the condensing of steam or draining of liquid from a system. The elimination of vacuum is necessary to allow proper drainage of liquid from process systems.

How It Works

The Vacuum Breaker functions like a simple check valve. Outside air is allowed to enter the system through the air inlet. However, when steam or water try to escape, the vacuum breaker closes off tightly.

Installation and Maintenance

Unit must be installed in a vertical position and should be placed at the highest point in the system.
