Oleodinamica Marchesini VN850 npt two-way ball valve

Oleodinamica Marchesini VN850 is the 1/2" NPT execution of the RS 2 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.

The two-way ball valve opens flow with the lever in line and closes it with the lever at 90 degrees. Follow the manufacturer connection diagram; the A and P line connections can be used in either direction for isolation.

The retained source table explicitly describes BSP female connections. Its corresponding V0850 row lists PN 500 bar and DN 13 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.
