Vent-Tech Model WZW water valves are air release and vacuum break valves designed to provide surge protection and seal at zero hydraulic head.
The Vent-Tech Model WTR clean water valve combines thirteen years of manufacturing experience with advanced Patent Pending flow designs.
The Vent-Tech model SZG sewer valves are air release and vacuum break valves designed to provide surge protection and seal at zero hydraulic head.
The Vent-Tech Model SWG sewer valve combines thirteen years of manufacturing experience with advanced Patent Pending flow designs.
The Vent-Tech Model SSG sewer valve is essentially a shorter version of the Model SWG air/vacuum relief valve, but with improved flow performance, less weight and better self-cleaning. In applications where clearance height is ample or valve weight is not a factor, specify the Model SWG valve, otherwise we recommend specifying the Model SSG.
Vent-Tech Model SDG sewer valve is essentially a shorter version of the zero pressure sealing Model SZG combination air/vacuum relief valve.
