Every valve tagged in one pass
Plastic valve tags engraved through a colored face to a contrasting core, so the letters are cut into the tag rather than printed on it. Pick the style once and the whole schedule follows it.
Made for the room they hang in
Tags colored to match the pipe they isolate, on brass chain or an S-hook, sized so the number reads from the floor.
Four shapes, seventeen sizes
Round for most valves, square for longer lines, octagon to make a shut-off stand out, rectangular for words. Every size shows its letter heights and price before you order.
What valve tags cost
Priced per tag by size and thickness, in Canadian dollars. No minimum, no setup charge, no extra for numbering.
1¼″, 1½″ and 2″ round tags cost the same — most people take the 2″ for the bigger letters.
| Tag | 1/16″ thick | 1/8″ thick |
|---|---|---|
| 1″ round | $1.14 | $1.34 |
| 1½″ round | $4.56 | $5.36 |
| 2″ round | $4.56 | $5.36 |
| 3″ round | $10.26 | $12.06 |
| 2″ square | $4.56 | $5.36 |
| 2″ octagon | $4.56 | $5.36 |
| 3″ × 1½″ rectangle | $6.84 | $8.04 |
| 4″ × 2″ rectangle | $9.12 | $10.72 |

- Check every tagEach one is drawn at its real size with its letter heights. Turn on the spec check and anything short is flagged.

Color-coded by service
Valve tags usually follow the pipe-marking colors of ASME A13.1 in the US, or CGSB 24.3 in Canada. The builder colors each tag from its abbreviation; you can override it.

|---|---|---|---|
| ARed / white | Fire quenching | Sprinkler and fire-fighting fluids | SPR, FP, SP |
| AOrange / black | Toxic & corrosive | Acids, caustics, chemical feed | CF, ACID, CAUS |
| AYellow / black | Flammable | Gas, and by custom steam and refrigerant | LPS, MPS, HPS, CR, RL, RS, RHG, GAS, LPG |
| AMedium Brown / white | Combustible | Oils and fuels | FO, DF, LO, HO |

A13.1 sets colors for pipe markers; valve tags borrow them by convention. Read the guide.
Plastic, brass or stainless?
Follow your specification. Where it allows engraved plastic, the tags can be color-matched to the pipe markers on each line.
| Compared | Engraved plastic (ours) | Brass | Stainless steel |
|---|---|---|---|
| Color | 10 color pairs, matched to the pipe markers | Brass only | Steel only |
| Marking | Laser engraved through a colored face to a contrasting core | Usually stamped, sometimes engraved and filled | Usually stamped or etched |
| Shapes | Round, square, octagon, rectangular | Mostly round | Mostly round |
| Choose it when | The spec allows plastic laminate or engraved tags | The spec names brass | The spec names stainless |
