The VB-060 is a normally closed full-bore vacuum breaker which is designed to open fully to allow the intake of air into the pipeline or system when vacuum conditions occur. The air valve protects the pipeline from negative pressure (vacuum) conditions caused by sudden shutoff of the pumps, pipe ruptures or the rapid draining of the pipeline.

Special Orifice seat/seal design
The combination of stainless steel and EDPM, assures long term maintenance-free operation.
