Oleodinamica Marchesini VC0800/PP120 VMPC 80 cartridge relief valve - prepared for sealing cap

Oleodinamica Marchesini VC0800/PP120 is a VMPC 80 cartridge relief valve with a 10–120 bar pressure setting range, maximum flow of 80 l/min and provision for a sealing cap. It uses a M26 × 1.5 mounting thread. The factory reference article is VC0800/120; the complete supplier-listed order code adds the documented control option.

The valve limits circuit pressure by opening from P to T when its setting is reached. Install it in the original manufacturer cavity, matching the threaded engagement, guide bore, oil passages and sealing shoulders. The mounting thread is a cartridge interface, not a BSP pipe port. The local PDF includes the full cavity cross-section and machining dimensions.

The manufacturer explicitly lists VC0800/120 for 10–120 bar and VC0800/300 for 50–300 bar. Both use the M26 × 1.5 mounting thread and the original cavity with a 24 H7 guide bore. The two pressure ranges are distinct ordered executions.

The pressure-range upper value is not a confirmed delivered preset. These sheets do not state a separate component maximum operating-pressure rating, so the range limit is not relabelled as that rating.

The /PP option means prepared for a sealing cap. It does not establish that a cap or tamper seal is supplied. The series image may show a standard control. Base-table mass is a reference only; an exact configured mass and external control envelope are not assigned.

The body is zinc-plated steel with standard BUNA-N seals and hardened, ground internal parts. The local PDF retains the complete relevant manufacturer article table, circuit, drawings and ordering notes unchanged.
