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
Available Configurations
- Standard – 4 functions
- Biased
- Flanged/Threaded Outlet
