Air Release

RBXc Air Release Valves

Vent-O-Mat Series RBX c

The original “Anti-Shock” & “Anti-Surge” air release and vacuum break valves for water, sewage, and effluent pipelines in FUSION BONDED EPOXY POWDER COATED ductile iron.

Vent-O-Mat Advantages & Key Features

  • 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
  • NSF61 approved
