Oleodinamica Marchesini V0890 DF 3 VIE 1/2 three-way diverter valve

Oleodinamica Marchesini V0890 (DF 3 VIE 1/2) is a three-way diverter valve with 1/2 inch BSP ports. The factory lists a maximum flow of 90 l/min and a pressure rating of 250 bar. These limits describe the exact size and execution; the ratings of adjacent models are not interchangeable.

Connect P to the pressure supply and A/B to the two circuit branches. One lever position sends flow from P to A; the other sends it from P to B. The standard neutral position connects P, A and B together. This is the open-centre article, not a separately ordered closed-centre execution.

The cast-iron body is rated by size: the smaller nominal connection does not imply the same pressure limit as every other DF 3 valve. The optional /CC closed-centre code is not part of this exact unsuffixed article.

The body material is cast iron, with hardened and ground steel internal parts and BUNA N seals. The local reference retains the complete relevant original code table, schematic, drawings, curves and conditions. Representative manufacturer product image for the DF 3 series. Port sizes and execution details depend on the exact article; use its factory table and original drawing in the local PDF.
