HYDRO SYSTEMS FOOT VALVES are designed to allow one-way flow of chemical concentrations. Water or diluted solutions are prevented from "backflowing" into any 1/4", 3/8" or 1/2" tube. Constructed of corrosion-resistant plastic and rubber materials for longer life.

Model 102 Valve is a foot valve only. It is standard with a step-down barb assembly that will work with 1/4", 3/8" or 1/2" tubing.

Ceramic Weights are used with the Model 102 Foot Valve. #113 Weight fits over 1/4" or 3/8" tubing. #114 Weight fits inside 1/2" tubing.
