Oleodinamica Marchesini V0990 IF 4 VIE 3/4 four-way reversing valve

Oleodinamica Marchesini V0990 (IF 4 VIE 3/4) is a four-way reversing valve with 3/4 inch BSP ports. The factory lists a maximum flow of 120 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 pressure, T to return and A/B to the double-acting actuator or hydraulic motor. In one working position P feeds A while B returns to T; in the other P feeds B while A returns to T. The standard centre closes all four ports. An open-centre /CA article is a separately ordered execution.

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 IF 4 series. Port sizes and execution details depend on the exact article; use its factory table and original drawing in the local PDF.
