DESCRIPTION
The Vent-Tech Air Relief Valves work in many different types of environments, protecting
pipeline infrastructure against the effects of water hammering and vacuum. High quality

superior design elements, these materials ensure that the valve operates in highly corrosive
environments within a wide range of pressures and temperatures. Each valve body contains air
flow enhancements to maximize flow under vacuum conditions.
All Vent-Tech Model SWG Sewage valves consist of 4 primary assemblies. These are:
