Waterra SS-16 Stainless Steel Foot Valve – Standard Flow

DescriptionA Waterra SS-16 Foot Valve (316 Stainless Steel) threads into Standard Flow Tubing  for sampling narrow diameter piezometers.The SS-16 Foot Valve is best used for narrow diameter wells as the Outside Diameter of the Valve is 16 mm (5/8 inch). It would fit nicely in a 1 inch ID well for instance.The Waterra SS-16 Foot Valve is recommended when there is concern about chemical inertness.An Acetal Thermoplastic (Delrin) alternative is the D-16 Foot Valve which also threads into the ID of the tubing.For 2 inch wells we would normally recommend a D-25 Foot Valve.The Standard System with an SS-16 Foot Valve can provide lifts of 150 feet (45 m). Flow rates can be as much as 1 gallon per minute (4.5 lpm).
