How To Do A Proper Valve Labeling?

Proper valve labeling is required to avoid accidents and injuries caused by spillage, which is caused by opening the wrong valve.

FREMONT, CA: Improving a facility’s safety and efficiency often is as simple as using proper valve labeling and identification practices. Although valves are not the main part of heavy machinery, still it can do damage if someone opens the wrong valve. Using the appropriate valve labeling practice will reduce several risks, including the risk of spills, accidents, and injuries caused by the valves.

Here are a few practices you should follow while adding valve labels:

Check which parts of the valve need to be labeled

There are hundreds of control valves and thousands of manual valves within a facility or refinery, so valve labeling and identification can be quite tricky. The main task is to properly label and identify growing numbers of valves that require repair, maintenance, and validation. There are valves that require identification on several different parts, including the body of the valve, bottom of the valve, and underside of the valve.

When choosing which parts of the valve need to be labeled, keep in mind that the objective of the tags and labels is to ensure safe operation. All tags and labels should be visible to everyone. According to the Department of Energy clearly states that labels for valve components should be permanently attached to the components in a way that will not interfere with the normal operational use or testing of the component. 

Utilize proper tag placement

Label and tag placement on pipes and valves is essential to facility safety. Facilities typically follow four general rules about placing pipe labels and valve tags; these rules follow recommendations from ANSI.

1• Lay pipe labels at all directional changes

2• Keep pipe labels on both sides of the entry points through floors and walls

3• Place valve tags beside to all valves and flanges

4• Place pipe labels at 25-50 foot intervals on straight runs

The best location to attach the valve tags is where workers will see the pipe contents and valve information before opening the valve itself. It is significant never to attach valves to valve stems or actuators. In some cases, tags are attached to valves using plastic or metal ties.

Use the proper type of valve tag

Valve tags can be made of anything, including wood, paper, metal, or plastic. The most popular among these is metal valve because it is more durable than others. They are available in a variety of metal types, including stainless steel, aluminum, and brass. Stainless steel tags can resist rusting and corroding, so they are considered ideal for environments that include water and chemicals. For situations that have low temperatures, aluminum tags are suitable because they are light weight and capable of being engraved. Brass tags are more robust and can be used in high-temperature situations in corrosive environments. Depending on the amount of information they need to contain, tags vary in size from small circles to large squares.
