Oleodinamica Marchesini V1827 V-101 3/8 DT NC normally closed end-of-stroke valve

Oleodinamica Marchesini V1827 is the V-101 3/8 DT NC double-blocking, normally closed mechanical end-of-stroke valve. It is rated for maximum flow of 30 l/min and maximum pressure of 300 bar, with a factory-listed mass of 0.786 kg and maximum pushbutton stroke of 10 mm.

At rest, the two opposed closure elements block the P/A path in both directions. Mechanical operation opens the path, as shown by the two-way connection in the factory symbol. It can be used to sequence actuators or provide an end-of-stroke discharge function according to the machine circuit.

The zinc-plated steel body contains hardened and ground internal parts with standard BUNA-N seals. The manufacturer pressure-drop curve applies to an effective stroke greater than 50 percent; it is not a claim that full rated flow is available at every partial stroke. Follow the original P/A circuit and travel drawing for the intended installation.

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.
