Oleodinamica Marchesini VC0200/V350 cartridge relief valve

Oleodinamica Marchesini VC0200/V350 is a VMPC 20 20 l/min screw-in cartridge pressure relief valve with handknob adjustment. The exact full order code is independently listed by Hikom. The original manufacturer size row gives maximum flow 20 l/min. The documents label a pressure setting range; no separate maximum operating-pressure rating is inferred from the spring endpoint.

Screw the cartridge into the specified 3/4-16 UNF cavity. This is a cartridge mounting thread, not an external BSP line port. The relief element opens from pressure P to return T when the adjusted setting is reached.

The supplier-linked legacy manufacturer sheet prints the exact VC0200/350 row with a 50-350 bar pressure range and explicitly defines the handknob and sealing-cap adjustment options. The current original uses the same VC0200/350 code with a 180-350 bar range and lists only P/PP adjustments. The editions are distinguished; no unqualified selected pressure range or delivered preset is assigned as a numeric filter.

The body is zinc-plated steel, with hardened and ground steel internals and standard BUNA-N seals. The factory describes a guided poppet with negligible leakage. The image is a representative manufacturer family photograph; the actual adjustment follows the exact supplier article and identified original edition. Mass and envelope or cavity dimensions are not transferred between different catalogue editions or adjustment options.

The local documentation should retain the complete current original spread and both pages of the supplier-linked legacy original, with their respective execution differences identified. Neighbouring sizes and alternative settings apply only to their named rows.
