Features & Benefits

 
  • High capacity air discharge during pipeline filling
  • High volume air intake for vacuum break purposes, both during draining of water pipelines and/or column separations
  • Independent third-party tested
  • Controlled pressurized air discharge releases air when pipelines are fully-charged
  • Surge relief prevents pipeline bursts during pump trip & rapid pipeline filling
  • More compact & shorter to accommodate existing installations and retrofits
  • Designed for low head sealing as well where line pressures are generally lower than normal
