This Pressure Reducing Valve (PRV) CAD Block library provides a set of DWG-style symbols for PRVs in multiple sizes, with typical side and end views for clear documentation. PRVs are widely used in plumbing systems to reduce and stabilize water pressure, protecting fixtures, valves, and equipment from excessive inlet pressure.
The block set is useful for drafting:
-
Domestic water incoming mains and zone pressure regulation
-
Booster/pump room piping schematics and layouts
-
Mechanical room details and service risers
-
Shop drawings and as-built plumbing documentation
Because the library includes multiple sizes and valve body representations, it helps you keep symbols consistent across plans while selecting the right PRV size for each line.
