RGXII Air Release Valves

The original “Anti-Shock” & “Anti-Surge” air release and vacuum break valves for water, sewage, and effluent pipelines.

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
More compact & shorter to accommodate existing installations and retrofits
Designed for low head sealing as well where line pressures are generally lower than normal
