From simple engraved valve IDs to heavy-duty stainless.
Use engraved aluminum for straightforward facility identification, cut-through stainless when visibility and durability matter most, or sequential cut-through sets when every valve needs a unique number.
Engraved Aluminum
Traditional lightweight valve identification in round, square and hexagon shapes.

Cut-Through Stainless
Characters are cut completely through stainless for identification that stays visible without relying on surface engraving alone.

Identification cut through the metal.
A strong fit where dust, grime, washdown or long service life make durable visibility a priority.
2" Square Cut-Through Stainless Valve Tags
Square stainless tags with custom text cut fully through the material.
Shop Square Cut-Through →2" Hexagon Cut-Through Stainless Valve Tags
Hexagon stainless construction with high-contrast open characters.
Shop Hexagon Cut-Through →Heavy-duty cut-through
Thicker stainless for demanding installations.
For exposed equipment, severe service and applications where a rigid tag is preferred over thin sheet metal.
2" Round 1/16" Heavy-Duty Cut-Through Tags
Rigid stainless construction with a substantial feel while remaining practical for hanging valve identification.
Shop 1/16" Heavy-Duty →2" Round 1/8" Heavy-Duty Cut-Through Tags
Extra-thick stainless for the most demanding permanent valve identification applications.
Shop 1/8" Heavy-Duty →Sequential cut-through
Number an entire valve system in order.
Choose round, square or hexagon shapes in 1.5" and 2" sizes. These sets are built for valve schedules where every tag receives a different sequential number.

Three matching tag sets for 200 air-cannon systems.
This completed project used 2-inch round, 20-gauge stainless tags with 0.75-inch-tall numbers cut through the metal and a 0.150-inch top mounting hole. Three matching 001–200 sets were grouped into six bundles and delivered in a custom waterproof case.
