This is a precise 3D model of a refrigeration service valve housing, designed for engineering applications such as spatial layout planning, interference checking, and system piping design. The model includes only the external shell — no internal mechanisms are included.

For hobbyists and makers, an STL file is provided for 3D printing as a display piece or functional prototype. Please note: the OBJ file is unprocessed and not optimized for real-time rendering — it is not suitable for use in game engines.
