Oleodinamica Marchesini VN873 npt three-way ball valve

Oleodinamica Marchesini VN873 is the 1 1/4" NPT execution of the RS 3 family. Its complete article code and NPT size are explicitly listed in the supplier catalogue. The original manufacturer sheet specifies NPT as an option with the VN code prefix; this actual code was observed as an offer, not generated from that ordering rule.

Connect P to supply and A/B to the alternative circuit branches. The standard L-port circuit selects one outlet with the lever at 90 degrees and the other with the lever in line. The separately identified 3K execution is not inferred from this unsuffixed NPT article.

The retained source table explicitly describes BSP female connections. Its corresponding V0873 row lists PN 350 bar and DN 25 mm. Those figures are labelled as BSP size-row references; no unqualified maximum-pressure, exact bore, envelope, mass or flow rating is assigned to this separately ordered NPT article without an NPT-specific row.

The original family specification uses a zinc-plated steel body, ground and chromium-plated steel internal parts, and BUNA-N/POM seals. The genuine family photograph may depict BSP connections; the selected article has the NPT connections named above.

The local technical PDF retains the complete relevant original manufacturer spread, including the exact size or kit row, option legend, hydraulic circuit and installation drawing. Adjacent executions apply only to their named rows.
