EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 60534-5 testing. This standard specifies the mandatory and supplementary markings of control valves.
Some mandatory markings may not be suitable for some specially designed valves and some additional markings may only be suitable for certain control valve types. Unless otherwise agreed between the manufacturer and the purchaser, it is recommended that the marking of all valves conform to this standard whenever possible.
Identifying the correct type of control valve for a particular industrial process control valve application requires information on the valve indicating the valve's key parameters. Methods for marking information based on the provisions of EN 19 and ISO 5209 are described in this part of IEC EN 60534.
Mandatory markings should be placed in such a way that the markings remain permanent. Mandatory markings must be on a marking plate (different from the identification plate) integral with or securely fixed to the valve body. The location of additional markings is also indicated. Usually, these are on an identification plate.
In addition, the standard specifies requirements for marking actuators, including the manufacturer's name, actuator type and size, and the maximum allowable pressure and temperature. The standard also provides guidelines for marking actuator accessories such as positioners and limit switches.
The purpose of IEC EN 60534-5 is to provide a standard method for marking control valves so that essential information is easily accessible to users. The standard helps ensure that control valves are installed and operated safely and efficiently by providing clear and concise information about the valve and its components.
In summary, IEC EN 60534-5 is a standard that specifies marking requirements for industrial process control valves, including valve body, actuator and accessory markings. The standard helps ensure the safe and efficient operation of control valves by providing users with clear and concise information.
