What does the “E” or “N” at the beginning of a valve part number mean (e.g., EVT3, NVT3, 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.
