THE IMPORTANCE OF THE SERIAL NUMBER
Your serial number is the unique identifier of your valve. It gives our teams direct access to all relevant information, including configuration, specifications, service history, and correct spare parts. Without this number, we need to manually identify your valve. This takes time and increases the risk of incorrect advice or parts.
Providing your serial number allows us to:
This results in faster support and reduced downtime.
THE LOCATION OF THE SERIAL NUMBER
The serial number is usually displayed on the valve's type plate, together with the component type, PO reference, and DMN order number. The serial number starts with either RV or DV. If the type plate is missing, the serial number is engraved on a designated part of the valve. If you are unable to locate the serial number, please contact our support team for assistance.

We recommend recording the serial number as soon as the valve is received. This makes future maintenance, spare parts identification, and service requests much easier.
Common ways to record the serial number include:
WHEN TO USE THE SERIAL NUMBER
Include your serial number in every support request. It helps us identify your valve quickly and maintain a complete service history. By keeping a record of all support interactions, we can keep track of supplied spare parts and updates, review previous issues, troubleshooting steps, and solutions whenever you contact us.
SUMMARY
Providing your serial number is the fastest way to receive correct and efficient support. Always include it when contacting DMN-WESTINGHOUSE for fast and accurate support.
