What must all valves be properly identified with?

All valves must be properly identified with the manufacturer's name or trademark to ensure traceability and compliance with safety standards. This identification allows operators and maintenance personnel to verify the origin of the valve, its specifications, and its suitability for specific applications. Knowing the manufacturer can also facilitate obtaining replacement parts or service and ensures that all components are of a known quality and reliability. Proper identification enhances safety by allowing users to refer to the manufacturer's guidelines or recall notices if necessary.

While information such as material type, size, usage instructions, and inspection dates are essential for operational safety and maintenance, the manufacturer's identification is a critical first step in ensuring that the valve meets the required standards and specifications for its intended application.
