Oleodinamica Marchesini V0875 RS 3 1 1/2" BSP 3-way ball valve

Oleodinamica Marchesini V0875 is an RS 3 3-way high-pressure ball valve with 1 1/2" BSP connections, a factory PN rating of 350 bar and nominal bore DN 25 mm. Its listed mass is 2.756 kg. PN is the pressure designation printed for this article; the sheet does not provide a temperature-dependent pressure derating schedule.

The L-port circuit diverts the P inlet to either A or B. In the manufacturer diagram, the lever at 90 degrees connects P to A; the in-line lever position connects P to B. It is not the T-port circuit. The separately specified /3K no-leakage execution is not included in this unsuffixed article, and a zero-leakage guarantee is not inferred from the generic family wording.

The A/P connection row (A/B/P on the three-way version) uses female BSP parallel threads under the factory DIN/150 228 BSP heading. The nominal inch thread size is distinct from the DN flow bore. NPT versions use different VN article codes and are not represented by this BSP article.

The body is zinc-plated steel with ground, chromium-plated steel internal parts and standard BUNA-N/POM sealing elements. Installation dimension L is 66.5 mm, overall length L1 is 124 mm and lever dimension L2 is 180 mm. Check lever clearance and connection details against the original drawing. Fixing holes are an optional /FF execution, not a feature assumed for this base article.

The local PDF retains the complete relevant original article table, circuit and drawings. A manufacturer series image is shown. No temperature range, viscosity range or maximum flow is invented from the DN designation.
