Oleodinamica Marchesini VC0200/180 VMPC 20 cartridge relief valve - screw adjustment

Oleodinamica Marchesini VC0200/180 is a VMPC 20 cartridge relief valve with a 10–180 bar pressure setting range, maximum flow of 20 l/min and screw adjustment. It uses a 3/4-16 UNF mounting thread. The factory reference article is VC0200/180.

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 applicable factory article VC0200/180 is explicitly listed with a 10–180 bar range and a 3/4-16 UNF thread. Its cavity drawing identifies a 2B internal thread class and a 12.7 H8 guide bore. An external thread class is not inferred from the cavity class.

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 standard screw-adjusted article has a factory-listed mass of 0.11 kg. Its setting range identifies the ordered spring execution and does not establish an exact preset.

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.
