Need a consistent butterfly valve symbol for a piping plan, riser, or HVAC coordination drawing? This Butterfly Valve CAD Blocks library provides reusable DWG-style representations for common drafting situations, including manual and actuated operator arrangements.
Use the blocks as drafting aids rather than as a substitute for the project valve specification. Before issuing a drawing, confirm the selected symbol reflects the valve arrangement, service, connection detail, and control requirements shown in the approved design documents.
This Butterfly Valve CAD Block library provides a DWG-style set of butterfly valve symbols in multiple sizes and configurations. The collection includes common representations used in mechanical drawings, including different operator styles (hand lever/gear) and actuated options where required for BMS-controlled systems.
Butterfly valves are widely used for isolation and flow control in larger diameter piping because they are compact, cost-effective, and easy to operate. These CAD blocks help you draft faster while keeping valve symbols consistent across your piping plans, risers, and schematics.
Use these blocks for:
-
Chilled water / hot water / condenser water piping systems
-
Plantroom headers, pumps, and equipment connections
-
HVAC shop drawings and coordination sets
-
Valve schedules and as-built documentation
Tip: Add your project tags (e.g., BV-01, size, service) next to the block so commissioning and maintenance teams can identify each valve quickly.

How to use the butterfly valve DWG blocks
Insert the appropriate block into the drawing, orient it to match the pipe run, and position the operator graphic so it remains clear at the intended drawing scale. Keep the valve symbol visually distinct from nearby fittings, equipment, and linework.
Coordinate the symbol with the valve schedule
A CAD block identifies the drafting representation; it does not by itself define the valve’s complete engineering data. Coordinate the symbol with the valve schedule and project specifications for items such as service, nominal size, connection type, materials, operating conditions, and actuation.
- Use a consistent block name and layer convention across the drawing set.
- Show the hand lever, gear operator, or actuator that matches the selected valve arrangement.
- Place the project tag beside the symbol so the drawing, schedule, and field documentation can be cross-referenced.
- Check that the block remains legible in plans, risers, schematics, and as-built documentation.
Related piping drafting references
For a complete piping layout, pair this valve-symbol resource with references covering pipe dimensions and schedules, flange dimensions, pipe fittings, and piping terminology. These resources help distinguish the graphical valve symbol from the dimensional and specification data required for coordination.
Before issuing a drawing
- Confirm the valve location and flow-control or isolation function with the design.
- Verify clearance for operation, maintenance, and actuator access.
- Check that the selected symbol agrees with the mechanical, controls, and BMS documentation where applicable.
- Review tags and references against the latest valve schedule before exporting or issuing the DWG.
Frequently asked questions
What is included in this butterfly valve CAD block library?
The library provides DWG-style butterfly valve symbols in multiple sizes and configurations, including hand-lever, gear, and actuated operator representations.
Where can these butterfly valve symbols be used?
They can be used in piping plans, risers, HVAC shop drawings, plantroom layouts, equipment connections, valve schedules, and as-built documentation.
Does the CAD block define the valve specification?
No. The block is a graphical drafting resource. Confirm the valve’s technical and project-specific requirements against the approved specification, schedule, and design documents.
How should the valve block be identified on a drawing?
Add the project tag and relevant identifying information beside the symbol. The source recommends including a tag, size, and service so commissioning and maintenance teams can identify the valve efficiently.
Are actuated butterfly valve symbols available?
Yes. The collection includes actuated options for applications where the valve is represented as part of a BMS-controlled system.
