Vacuum Breaker Valve VBV Series

This HorizonPSI vacuum breaker valve is utilized to allow for free air to be drawn into a vacuum system.  It utilizes a rubber disc that seats against the valve body and when in the retracted position allows air to be drawn into the system at that location.  This valve is typically utilized to “purge” the conveying line when the feed point into a vacuum system cannot be isolated (e.g., rotary airlock, screw feeder, etc.).

  • Fabricated housing
  • Fabricated line adaptor
