IWN SERIES for anti-theft, brackish water and potable water.

The NUVENT IWN SERIES is a 4 function (triple acting) air release and vacuum break valve. They combine high volume air release, anti slam air release, pressurized air release and vacuum break all in one compact tubular design. 

Only WRAS / NSF 61 approved materials are used in our valves, thereby ensuring no contamination occurs when used with potable water. 

As the IWN is made from robust nylon, there is very little worth at the scrap dealer. This ensures that the valve will remain installed for the lifespan of the air valve.
