International Valve Water Valves
Water Valve WTR
The Vent Tech Model WTR clean water valve combines thirteen years of manufacturing experience with advanced Patent Pending flow designs. The Model WTR was engineered to expand and improve the technological advances of the flat float air/vacuum valve.
Water Valve Model WZW
The Vent Tech Model WZW water valves are air release and vacuum break valves designed to provide surge protection and seal at zero hydraulic head (i.e. no reliance on a minimum pipeline pressure to achieve seal). If the HGL is expected to be consistently maintained above 3 psi then use a Model WTR valve, otherwise we recommend specifying the WZW.
Water Valve WZR
The Vent-Tech Model WZR Zero Pressure Sealing Series C, B, V and N potable water air release and vacuum relief valves are ruggedly constructed to provide years of trouble-free, low maintenance operation. These instructions provide the proper Op- eration and Maintenance information for use by personnel who are responsible for the operation and maintenance of Vent- Tech Models WZR Zero Pressure Sealing Series C, B, V and N water air release and vacuum relief valves.
Water Valve WTW
The Vent-Tech Model WTW clean water valve combines thirteen years of manufacturing experience with advanced Patent Pending flow designs. The Model WTW was engineered to expand and improve the technological advances of the flat float air/ vacuum valve.
