Oleodinamica Marchesini V0666 VU2P 1/4 shuttle valve

Oleodinamica Marchesini V0666 is the VU2P 1/4 shuttle valve with 1/4" BSP connections, maximum flow of 30 l/min and maximum pressure of 350 bar. The factory table lists a mass of 0.560 kg. A ball selector passes the higher of two independent pressure signals to the common outlet.

Connect the two P ports to the pressure lines being compared and U to the circuit being supplied. The lower-pressure branch is isolated by the shuttle. This is a pressure-selection function rather than simultaneous mixing of both supplies.

The body is zinc-plated steel with standard BUNA-N seals. Its original drawing identifies body length L of 60 mm and total dimension L1 of 104 mm; these must not be substituted for one another when checking installation space. The local PDF retains the complete pressure-drop and installation information.

The local PDF retains the complete applicable original manufacturer spread, including the article table, hydraulic symbol, drawings and ordering notes. Where curves specify oil at 50 °C and 30 cSt, these are curve reference conditions rather than an operating-temperature limit.
