Brass Spring Check Valves

Brass check valves are typically used as backflow preventers for water, air, oil and other media compatible with the materials of construction. Concentric design, lead-free check valves can be used in vertical and horizontal applications. Spring loaded design reduces water hammer. Suitable for non-viscous, smooth-flowing non-particulate media. Certified to NSF 61 and NSF 372 as lead free and suitable for potable water.
