Oleodinamica Marchesini V0790/F10 hose-burst valve cartridge — 1 mm bleed hole

Oleodinamica Marchesini V0790/F10 is a hose-burst valve cartridge with a 1/2" BSP interface and a 1 mm bleed hole in the sealing plate, explicitly stated in the selected supplier offer. The factory CODE/F legend requires the hole size to be specified; this diameter comes from the exact offered execution, not from expanding a configurator.

This is the cartridge only, without an in-line housing. The original V0790 row gives 80 l/min and a 350 bar component limit. The selected full SKU V0790/F10 explicitly describes a 1 mm hole; F10 is not treated as a universal manufacturer suffix rule for other sizes or offers.

A hose-burst valve reacts when flow exceeds its adjusted reaction threshold. The bleed hole permits slow load descent even after closure; this is not a zero-leakage load-holding device. The manufacturer specifically distinguishes VUBA from a load-holding valve or a unidirectional restrictor and recommends a downstream flow-control valve. The reaction-flow setting is not established by the 1 mm hole diameter or by the maximum-flow rating.
