EconomyLine-CheckValve2

Inch ThreadsDescriptionThis miniature check valve line em-ploys a free floating stainless steel or elastomeric ball, which allows free flow in one direction; reverse flow is pre-vented.Thevalvesaresuitableforair,water, inert gases, light oil and liquids compatible with the materials of con-struction. The valves are fast acting and are suitable for long life applications.
