About Addimax’s Valve Tags

Worldwide demand for industrial valves continues to increase at a rapid pace. Valves play a critical role in managing the flow of liquids and gasses within engineered systems. In some cases, the materials themselves may be hazardous, or they may be stored at high pressure. The need for organized procedures and safety protocols is critical. One of the easiest ways to inform employees and contractors who use these valve systems is to implement a valve tagging program. While each facility and system will be different, there are some excellent best practices that can help you get started.

Properly tagging valves in a facility requires a good amount of preparation to be successful. We’ve created this guide to cover all the important tips and ideas that can help you implement a robust system for tagging valves.

In this guide, we’ll cover the following topics:

What Are the Benefits of Tagging Valves?

The utility pipes that run through a typical commercial building are often part of a complex system. There may be different configurations between warehouses, factories, and office facilities, but there are always many valves present. Some buildings have hundreds or even thousands of valves that each have a specific purpose. These are some of the most obvious benefits of tagging valves.

Identifying and recognizing the technical specifications of a valve is important for several reasons, the primary one being safety. Valve tags allow you to highlight any safety warnings using specific colors or information. Combined with safety signs and other facility labels, valve tags help communicate the potential dangers that may be found in each location.

Proper safety communication helps facilitate maintenance activities and other work that must be done to operate local equipment. Valve tags that include barcodes can help employees and contractors access service records and other important safety information. Using a comprehensive valve tagging system helps prevent human error and supports a robust asset management platform.

Valve Tagging Standards & Regulations

Within the United States, the regulations that govern the placement of pipes with a facility are well-documented by the American National Standards Institute (ANSI) and the American Society of Mechanical Engineers (ASME). In Europe, the British Standards Institution (BSI) is the most widely referenced organization for similar information. While many of these standards do not identify unique requirements for valves, these components are considered part of piping systems, and many of the general guidelines apply. These are a few of the most important points regarding valve tagging which are referenced in the following standards.

Valve Tagging Standards & Regulations

ANSI/ASME A13.1. This is the U.S. standard that applies to general pipe marking. Valves that are part of a larger system must be tagged with an identifying label. A tag numbering system is usually the best way to achieve this, and the color of any identifying marks should follow the recommended six predefined colors. They are:

Fire-quenching fluids: White text on red background

Toxic or corrosive fluids: Black text on orange background

Flammable or oxidizing fluids: Black text on yellow background

Combustible fluids: White text on brown background

Other water: White text on green background

Compressed air or other gases: White text on blue background

In addition to these colors, facility management may also select user-defined tags based on additional colors that are defined in the standard. Always consult the latest version of any standards to confirm specific information.

NFPA99. In addition to ASME and ANSI, the National Fire Protection Association (NFPA) has its own set of safety standards that can be a useful reference for valve tagging. These regulations focus on the use of valves within identified zones inside a building. You will find specifications for marking, identification, and inspection that apply to valves that are newly installed during construction or operated within existing facilities.

IIAR Bulletin No. 114. This bulletin, from the International Institute of Ammonia Refrigeration (IIAR), applies to refrigeration units that utilize ammonia. Sections 7.2 and 7.4 discuss the use of proper color coding for valves that are part of these systems.

BS 1710-2014. This standard for identifying pipelines and services is used throughout Europe. Topics include pipe marking guidelines for facility systems, refrigeration units, and water treatment equipment. Similar to the U.S. regulations, many of the details that apply to pipes are also applicable to valves since they are connected to the same systems.

Types of Valve Tags

The most common industrial valve tags are typically identified by the type of valve to which they are attached. Since many facilities contain a combination of HVAC units, boilers, refrigeration units, and other equipment, this helps to simplify the categories. The following are a few of the most common applications for valve tags.

Chemical Valve Tags

These tags are used to mark valves that are connected to pipes that carry chemicals. Due to the potential hazards of these materials, safety is the primary concern for these tags. Using a clear color scheme with proper tags for each type of chemical valve, you can clearly identify each material and maintain a high level of safety.

Waste/Water Pipe Valve Tags

Any pipes which carry water, waste, or other liquids in a facility should also be tagged with standardized labels. Since nearly every commercial or residential facility includes at least a basic water management infrastructure, there are usually color-coded labels for some components already present. In these situations, you can often match your valve tags to the existing color schemes.

Gas Valve Tags

Gasses that are delivered through pipes in a facility are usually maintained at high pressure. This characteristic, along with the fact that so many types of gasses exist, requires careful planning for appropriately tagging the connected valves. The standardized colors set by appropriate regulations should be used to avoid any confusion.

Valve Tag Materials

Valve tags can be fabricated using a number of different materials. It is always best to choose a material based on the specific environment for each valve application. Determining the most compatible material from the start will save you time and reduce the risk of damage to your labels.

Metal Valve Tags

Metal is an excellent choice for a valve tag material due to the generally high durability and level of customization available. Since metal tags are usually very rigid, a plastic or metal chain can be used to attach the tag to the valve.

Aluminum. Aluminum is generally lightweight metal that has excellent durability. The most common types found in labels and tags are anodized aluminum and Metalphoto® photosensitive anodized aluminum. Both versions have graphics that are sealed beneath a protective layer. Metalphoto is one of the most durable materials available and is well-suited for use in the most demanding applications.

Stainless Steel. The high density of stainless steel makes it a very clean metal that is known for its antimicrobial properties. It is an excellent choice for marking valves that are used in food processing and packaging facilities.

Brass. With a distinctive golden metallic appearance, brass is often chosen for applications where the look of the tag is important. Using a brass valve tag adds a certain level of quality to the design. It is softer than many other metals and is best used for applications in environments that are not overly demanding.

Plastic Valve Tags

Since plastic is easy to mold and conform to customized dimensions, this material is a popular choice for valve tags. Especially at higher volumes, plastic valve tags can be an economical option for use with custom printed and reusable labels. The most common standard plastics used for valve tags are polyester, polycarbonate, and vinyl.

Proper Valve Tag Placement

The standards provided by ANSI are a robust resource for understanding best practices for valve tag placement. In general terms, these are some of the most important tips to keep in mind when adding your tags to each valve. Valve tags should:

Be easily accessible

Be clearly visible from different angles

Avoid valve stems, actuators, or other interfering components

You should also ensure that valve tags do NOT:

Interfere with the movement and operation of the valve

Conflict with other equipment labels or safety signage

If you distribute your valve tags in an organized way, they can provide a great benefit for your team’s productivity and the overall efficiency of your operation. Always favor clear and consistent design elements, and whenever you have doubts regarding the suitability of a valve tag design, always consult the appropriate regulations.
