Oleodinamica Marchesini V0794 VUBA 1/2 DIN T15L din 2353 hose burst valve

Oleodinamica Marchesini V0794 is the VUBA 1/2 DIN T15L din 2353 hose burst valve, with factory maximum flow 80 l/min, maximum operating pressure 350 bar and mass 0.074 kg.

This execution combines the 1/2" BSP cartridge connection with the DIN 2353 light-series connection for 15 mm tube. The metric connection thread is M22 × 1.5. The factory drawing lists plate-gap reference S of 1.6 mm, catalogue dimension L1 of 19.5 mm and hexagon size 27 mm.

The printed L entry requires clarification against the drawing, so no structured L dimension is assigned. The original drawing is retained in the local PDF.

Install V towards supply and C towards the actuator. If actuator outflow exceeds the adjusted reaction flow, the valve closes to limit uncontrolled descent after hose failure. The manufacturer states that this device is neither a load-holding check valve nor a one-way flow restrictor and recommends a downstream flow-control valve.

The manufacturer recommends a reaction-flow setting of about 1.5 times the system flow. The listed maximum flow and drawing gap S are separate references, not a verified delivered calibration. Hole-on-plate and preset options apply only to separately specified articles and are not inferred for this model.

The local technical PDF retains the complete applicable original manufacturer spread. Neighbouring sizes and optional configurations apply only where explicitly identified. Any 50 °C oil temperature and 30 cSt viscosity shown with curves are reference conditions rather than independent operating limits.
