WVBSS Vacuum Breaker

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

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

Air Vents (AV2000)

Air vents are used in steam systems for the removal of air and other non-condensable gases from process equipment, vessels and piping. Place at end of steam main and directly on process equipment.

Vacuum Breaker (WVBSS)

Vacuum breakers allow air to enter a system in order to “break the vacuum.” In a heat exchanger, the vacuum is caused by condensing steam which inhibits condensate drainage.

Drainage of liquids from storage tanks will also cause an undesirable vacuum which inhibits flow or can possibly collapse tank or vessel.

The WVBSS Series Vacuum Breaker is used on heat exchangers, air coils, jacketed kettles, pressing machines, boiler feed water tanks, sparge system, water line or anywhere else an unwanted vacuum can occur. It is a very important item in any steam system as it allows for the proper drainage of condensate by releasing or "breaking" vacuums that may be formed during steam condensation. It is also important to use on a tank when liquid is being pumped out. An unwanted vacuum can stop the pumping action as well as collapse a tank.
