This Standard Practice covers in-line, internally spring-loaded (a), center-guided check valves made of gray iron or ductile iron. These valves, having the feature of limiting fluid flow to one direction only, are intended for use with clean fluids (i.e., fluids that do not contain solids), including potable water (b), waterworks, and other industrial applications, in horizontal and vertical installations.
NOTES: (a) A spring-loaded, also known as spring-assisted, check valve incorporates a spring to assist in closing the check valve.
(b) Potable water is defined as safe and satisfactory for drinking and cooking.
