The purpose of marking the valve body by the manufacturer is primarily to indicate the service ratings. This marking serves as an essential guideline for users to understand the specifications and limitations of the valve. Service ratings provide crucial information regarding the maximum pressure and temperature the valve can handle safely, ensuring that it is used correctly within its designed operational parameters. By clearly marking these ratings, manufacturers help to prevent misuse and enhance safety, as operators can easily identify whether a specific valve is suitable for their intended application. This ensures adherence to safety standards and regulatory compliance in CNG applications.
