Jet Flo Plastic Stock tank valve. Ritchie has made a metal version and a plastic version of a stock tank valve for years. As of February, 19th, 2014 they will no longer produce them. We still have stock so we’ll keep these on the website for now. The great price shown will be good till existing stock is depleted. Normal Ritchie list price for these is $80.00. These tank valves clamp on the side of a stock tank and you run a water line or garden hose to them to supply water to it. They use the same great and reliable valves as does the Ritchie fountains.
