What is the purpose of the service designation marking on valves?

The service designation marking on valves serves a crucial role in clearly specifying the intended service for which the valve is meant. This marking provides important information about the operational context of the valve, such as whether it is suitable for steam, water, or gas services. By having this designation, operators and maintenance personnel can quickly identify the applications for which a valve is rated, ensuring correct usage and compliance with safety standards.

The specific designation helps prevent improper installation or operation, reducing the risk of accidents and equipment failure. When valves are correctly matched to their designated services, it contributes to the reliability and efficiency of an entire system. Thus, the primary purpose of the service designation marking is to guide users in selecting the appropriate valve for their specific needs.
