Valve and lockout tag labels

The Solution to Valve Labeling

A standard label is not enough when it comes to valve and lockout labeling. Because of the various shapes of valves and locations where valves are used, you may not be able to locate a surface to apply a standard label. Valve tags are the solution. Simply print your custom label, apply it to the valve tag, then fasten the valve tag in place where you need it. Valve tags can be used anywhere.

ANSI ASME Y1.1-1989 Codes

Since you have limited space on a valve tag, it is recommended that you use pre-defined abbreviations or codes on your tags to save space. Below is a list of pre-defined, approved codes for use on valve tags.
