This is the modern copy of the old 1/4" Turn Valves (Zwickle). It has a ledge to attach a pigtail or a CO2 checker. The valve is designed to clean in place as long as the valve remains open for the cleaning cycle.

Note: The valve has a small pocket in the moving part that traps wort when closed so we don't recomend these for active fermentations.

This is a replacement option for the sample valve for MB conical fermenters and brite tanks.
