Control Valve CAD Blocks help engineers, designers, and drafters represent modulating valves consistently across HVAC and mechanical documentation. This ARI DWG resource focuses on reusable valve symbols, body configurations, and actuator or handwheel views for coordinated piping drawings.
Use the block library as a drafting reference rather than as a substitute for valve selection, control-sequence review, or project-specific engineering. The symbol should communicate the intended valve arrangement clearly while the design documents establish service, connection requirements, control function, and equipment coordination.
This Control Valve CAD Block library provides a wide set of DWG-style symbols for control valves in multiple sizes and configurations. The collection includes typical valve body views and actuator/handwheel variations, making it useful for HVAC and mechanical drawings where modulation and automatic control are required.
Control valves are commonly used to regulate flow and temperature in systems such as chilled water, hot water, condenser water, and sometimes steam/process lines. With multiple sizes shown, these blocks help you keep drawings consistent and quickly select the correct valve representation for your piping schematic, riser, or mechanical room layout.
Use this CAD block set for:
-
AHU/FCU coil control valves (2-way / 3-way applications depending on design)
-
Heat exchanger and plantroom control piping
-
BMS/controls coordination drawings and valve schedules
-
Shop drawings and as-built documentation
Tip: Place these blocks on a dedicated “VALVE-CONTROL” layer and add tags (CV-#, size, service) to speed up coordination and commissioning.

How to use the ARI control valve DWG blocks
Before inserting a block, identify the drawing purpose: a schematic, riser, mechanical-room layout, shop drawing, or as-built record. A schematic may need a clear flow-control symbol, while a layout may also require an actuator orientation that can be coordinated with access and nearby equipment.
Choose the representation that matches the control function
The source library includes valve body views and actuator or handwheel variations. Select the representation that best communicates whether the valve is part of an automated control assembly or a manually operated arrangement. For coil and plantroom drawings, keep the symbol consistent with the project legend and valve schedule.
Coordinate size and service information separately
The available blocks show multiple sizes, but a CAD symbol does not by itself confirm the required valve size, connection detail, flow characteristic, actuator performance, or compatibility with the system. Confirm those items against the approved design documents and equipment information before issuing a drawing.
Recommended drafting workflow
- Insert the block on a dedicated VALVE-CONTROL layer, following the layer convention already used by the project.
- Add a valve tag, size, and service description so the symbol can be matched to the valve schedule and controls documentation.
- Check the symbol against the project legend and the intended two-way or three-way application.
- Coordinate the valve, actuator, nearby fittings, access zones, and instrumentation before releasing the drawing.
- Retain the original block orientation and scale conventions used by the drawing set unless the project CAD standard requires otherwise.

Control Valve CAD Block FAQ
What is included in this control valve DWG library?
The library provides DWG-style control valve symbols in multiple sizes and configurations, including typical valve body views and actuator or handwheel variations.
Where can these control valve blocks be used?
They can support HVAC schematics, chilled-water and hot-water drawings, condenser-water documentation, heat-exchanger piping, plantroom layouts, BMS coordination drawings, shop drawings, and as-built documentation. Confirm the actual service and arrangement from the project design.
Does the CAD block determine the correct valve size?
No. The block communicates the valve representation for drafting. The required size and valve specification must be verified against the approved piping design, valve schedule, equipment information, and control requirements.
How should control valve blocks be organized in a CAD file?
Use a consistent layer such as VALVE-CONTROL where appropriate, then add the project valve tag, size, and service information. Follow the project’s CAD standards if they use different layer names or tagging rules.
Can the blocks be used for two-way and three-way control valves?
The source content identifies AHU and FCU coil control valve applications that may use two-way or three-way arrangements depending on the design. Confirm the required arrangement before selecting and labeling the block.
