This Check Valve CAD Block library provides DWG-style symbols for non-return valves (NRV) in multiple sizes and configurations. The set includes typical valve representations used in mechanical and plumbing drawings, helping you draft faster and keep valve symbols consistent across plans, risers, and schematics.
Check valves are essential for preventing reverse flow in piping systems—commonly installed on pump discharge lines, equipment branches, and vertical risers to protect pumps, maintain system stability, and avoid backflow issues.
Use these CAD blocks for:
-
Chilled water / hot water / condenser water hydronic systems
-
Pump rooms and mechanical plant piping details
-
Domestic water and utility piping schematics
-
HVAC shop drawings and as-built documentation
Tip: Add tags like CV/NRV-01, pipe size, and service (CHW/HW/CW/DW) next to the block to support commissioning and maintenance teams.
