Oleodinamica Marchesini V0784 VUBA 3/8 DIN T10L din 2353 hose burst valve

Oleodinamica Marchesini V0784 is the VUBA 3/8 DIN T10L adjustable hose burst valve, rated for maximum flow of 50 l/min and maximum pressure of 350 bar. It combines the 3/8" BSP interface with the M16 × 1.5 DIN 2353 connection for 10 mm outside-diameter light-series tube. Its mass is 0.042 kg.

The 10L tube designation and M16 × 1.5 metric thread are separate from the BSP interface. Compare the original sectional drawing with the actual valve/cylinder connection before installation. The zinc-plated steel body uses a burnished steel sealing plate.

Connect V towards supply and C towards the actuator. Excessive actuator outflow causes the plate to shut. This is a hose-failure excess-flow device, not a substitute for a load-holding check valve or one-way restrictor; the manufacturer recommends a downstream flow-control valve.

The drawing lists plate gap S as 1.2 mm. The manufacturer recommends reaction flow around 1.5 times system flow and offers other calibrated gaps or specified bleed holes. No custom reaction-flow preset or hole diameter is inferred from this standard article.

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.
