WVBSS Series — Stainless Steel Vacuum Breakers

The WVBSS Series Vacuum Breakers are stainless steel devices designed to prevent unwanted vacuum conditions in steam and liquid systems. Installed on heat exchangers, air coils, jacketed vessels, and piping systems, they protect equipment from collapse, flow interruption, and condensate drainage problems.

Technical Specifications

Operating Principles

When system pressure falls below atmospheric, the internal valve opens automatically to allow air in and equalize pressure. Once normal pressure is restored, the valve closes to prevent steam or fluid leakage. No external controls or manual intervention required.

Model

Applications

• Heat exchangers
• Air coils and steam coils
• Jacketed vessels and tanks
• Steam and condensate piping systems
• Liquid pumping and drainage systems

Note: Install at the highest point of the system or vessel for proper vacuum relief.
