IWFa SERIES for potable water.

The NUVENT IWFa SERIES is a 3 function (single acting) air release valve. They combine high volume air release, anti slam and pressurized air release all in one compact tubular design.

The vacuum break function has been removed for this design. 

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