What does the “E” or “N” at the beginning of a valve part number mean (e.g., EVT3, NVT3, etc.)?
-
The “E” and “N” valve part number prefixes are region codes: “E” is for Europe and “N” is for North America.
They are no longer used, and so the standard part number is the same excluding the “E” or “N.”
Note that the thread type symbol may have been omitted from the part number depending on the region.
When replacing the product, be sure to confirm the thread type beforehand.
Example of valve series with an “E” prefix: EVT3, EVO3, EVK, EVP, EVF, EVS, EVN, EVY, etc.
For valves which had an “E” prefix, the thread type now needs to be indicated in the part number (e.g., symbol “F” for G thread).
Valve part number example: EVT307-5DO-01-Q→VT307-5DO-01F-Q
Example of valve series with an “N” prefix: NVT3, NVO3, NVK, NVP, NVF, NVS, NVN, NVY, etc.
Similarly, for valves which had an “N” prefix, the thread type now needs to be indicated in the part number (e.g., symbol “N” for NPT thread or “T” for NPTF thread)
Valve part number example: Plug-in type NVT307-5DO-01→VT307-5DO-01T
Be aware that NVFR/NVFS series valves were of the body ground type.
If body grounding is required, suffix a “-Q” to the part number.
Note) This information does not apply to EVS7/EVS1 series ISO valves for use in Europe, as the “E” is a part of the part number rather than a prefix.
