These globe valve butt-weld end CAD blocks provide a practical starting point for piping layouts that use welded valve connections. The ARI DWG library is organized by nominal DN size from DN15 through DN350, helping drafters locate an appropriate symbol for mechanical, process, and plant piping drawings.
Use the blocks alongside your project’s piping specifications, valve schedule, and approved manufacturer data. A CAD symbol supports drawing production, but it does not by itself define the valve’s pressure class, materials, end preparation, face-to-face dimension, or installation requirements.
This Globe Valve Butt-Weld End CAD Block library provides DWG-style valve symbols for globe valves with butt-weld connections, arranged by DN sizes for fast selection in piping drawings. Butt-weld end valves are commonly used in welded steel piping systems where strength, reliability, and leak resistance are important—such as plantrooms, district cooling/heating, and industrial services.
The block set includes typical valve views and size variations, making it useful for:
-
Welded hydronic systems (CHW/HW/CW)
-
Steam and process piping schematics
-
Mechanical room piping layouts and risers
-
Shop drawings and as-built documentation
Tip: Tag each valve in your drawings (e.g., GV-01, DN size, service) to support valve schedules and commissioning.

How to use the globe valve CAD blocks
Select the block that matches the nominal size and valve arrangement required by the drawing. Place it in the piping route, orient the valve to match the flow and access arrangement shown in the design, and maintain consistent layer, lineweight, and annotation conventions throughout the file.
Reference information to confirm
- Nominal size: Match the DN designation to the connected piping and the project valve schedule.
- Connection type: Confirm that the valve is intended for butt-weld installation rather than a flanged, threaded, or socket-weld connection.
- Service: Identify the applicable system, such as chilled water, hot water, cooling water, steam, or process piping.
- Valve data: Verify material, pressure-temperature limits, actuation, flow direction, and dimensional data against approved technical documentation.
- Documentation: Tag the valve consistently so the drawing can be coordinated with the valve schedule, commissioning records, and as-built set.
Related piping references
For coordinated drafting, pair this block library with references covering pipe dimensions and schedules, butt-weld fittings, flange terminology, and piping isometric drafting. Those references help distinguish nominal designations from actual outside diameter, wall thickness, connection geometry, and layout requirements.
Before issuing a shop drawing, compare the selected block with the project specification and the manufacturer’s current dimensional drawing. The downloaded DWG should be treated as a drafting resource, not as a substitute for engineering review or fabrication documentation.
Frequently asked questions
What does DN indicate in these CAD blocks?
DN is a nominal size designation used to identify the valve and its connected piping size. It should be coordinated with the project piping schedule and should not be assumed to represent every physical valve dimension.
Are these blocks suitable for butt-weld piping layouts?
Yes. The library is intended for globe valves shown with butt-weld connections. Confirm the actual end preparation and dimensional requirements with the approved valve data before fabrication or installation.
Can the CAD block be used to determine valve pressure rating?
No. The drawing block identifies the valve graphically and by nominal size, but pressure rating, material, temperature limits, and service suitability must come from the project specification and manufacturer documentation.
How should the valve be identified on a drawing?
Assign a unique tag and coordinate it with the nominal size, service, line number, and valve schedule. Consistent identification improves design review, procurement, commissioning, and as-built documentation.
