Oleodinamica Marchesini V0860/FF RS 2 VIE 3/4 /FF 2-way ball valve with fixing holes

Oleodinamica Marchesini V0860/FF is the RS 2 VIE 3/4 two-way ball valve with the factory /FF fixing-hole execution. The female connections are 3/4" BSP, the factory rated-pressure designation is PN 400 bar and the nominal bore is DN 20 mm.

The /FF suffix identifies the supplied fixing holes shown in the factory drawing. The exact full article is selected on the supplier page and listed on the current manufacturer series page; it is distinct from the standard V0860 article. The factory drawing gives a fixing-hole diameter of 6.25 mm. It is not an NPT or DIN 2353 metric connection variant.

Connect A or P to the line to be isolated. The valve blocks flow with the manual lever at 90 degrees to the body and permits flow with the lever in line. The body is zinc-plated steel, with ground and chromium-plated steel internals and standard BUNA-N/POM sealing. The manufacturer describes the shut-off arrangement as not permitting leakage.

PN is the factory rated-pressure designation, not an independently verified continuous-duty pressure limit for every fluid and temperature. The base-size table lists mass 1.460 kg, body dimension L of 62.5 mm and overall dimension L1 of 95 mm. These remain explicitly labelled base-execution references because the sheet does not provide a separate /FF mass. The applicable original drawing governs the supplied fixing-hole execution.

The local technical PDF retains the complete applicable original manufacturer spread. Neighbouring sizes and optional configurations apply only where explicitly identified. Any 50 °C oil temperature and 30 cSt viscosity shown with curves are reference conditions rather than independent operating limits.
