Oleodinamica Marchesini V0720/V180 VMP 3/4 relief valve - handknob

Oleodinamica Marchesini V0720/V180 is a VMP 3/4 relief valve with 3/4" BSP connections, a 10–180 bar spring setting range, maximum flow of 90 l/min and handknob adjustment. The factory base designation is V0720. The supplier lists this complete order code; the manufacturer sheet confirms the base valve, spring range and control option.

The VMP valve opens a path from P to tank T when circuit pressure reaches its setting. The manufacturer describes the P connection as reversible and shows a plugged pressure-gauge provision. A gauge thread size is not assigned where the drawing does not specify one. The factory maximum operating pressure is 350 bar, separate from the 10–180 bar spring range.

The original spring table gives a standard setting reference of 90 bar for 10–180 bar springs. The delivered setting is not independently established. Use the original pressure/flow curves at 50 °C and 30 cSt as reference conditions, not as an operating-temperature specification.

The /V option is handknob adjustment. The series image and base drawing may show a standard control. Base-table mass is a reference only; the configured handknob mass and its external envelope are not independently established.

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.
