I understand you're looking for a Proteus library containing solenoid valve models, specifically for a portable (no-install) version of Proteus.

SnapMagic: Offers a vast collection of searchable Proteus libraries by part number or keyword at SnapMagic (formerly SnapEDA). How to Install (Portable & Standard)

Step 3: Refresh the Library Cache

Since Proteus Portable does not automatically scan new libraries:

• SOLVALVE.LIB (the library data)
• SOLVALVE.IDX (the index file)
• SOLVALVE.HEX (optional example firmware)
• README.txt

After downloading, the files usually come in a .zip or .rar archive.
