Oleodinamica Marchesini V0879/AP DF 3 VIE 1/4 AP ACC. high-pressure three-way diverter valve

Oleodinamica Marchesini V0879/AP (DF 3 VIE 1/4 AP ACC.) is a high-pressure three-way diverter valve with 1/4 inch BSP ports. The factory lists a maximum flow of 40 l/min and a pressure rating of 500 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 AP execution uses a steel body and BUNA N seals with anti-extrusion rings for the factory 500 bar rating. It is distinct from the cast-iron DF 3 size with a similar nominal thread. The /APCC closed-centre execution is separately ordered and is not this /AP article.

The body material is steel, 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 AP series. Port sizes and execution details depend on the exact article; use its factory table and original drawing in the local PDF.
