We can engrave a wide range of valve labelling tags, including larger solid brass ones, Traffolyte/laminate versions, coloured aluminium and economy ABS plastic versions.  These are great for labelling pipework, ductwork or internal roofing panels.  The brass valve tags are deep engraved then black filled for strength and excellent visibility.  The large laminate/Traffolyte tags can also be engraved with text or numbers are good if you are after colour coordinating them.  We also do lightweight, strong and visually striking anodised aluminium valve tags, these are particularly striking with text on, offering great contrasting. If you require a cheap numbering system with fewer characters then the 30mm economy ABS valve tags are a popular option.
