Oleodinamica Marchesini V0732/PP180 VMPD 3/8 double relief valve - prepared for sealing cap

Oleodinamica Marchesini V0732/PP180 is a VMPD 3/8 double relief valve with 3/8" BSP connections, a 10–180 bar spring setting range and provision for a sealing cap. Its manufacturer base designation is V0732. The full order code is listed by the supplier; the manufacturer sheet confirms the base valve, spring range and control option.

The applicable factory base has a maximum operating pressure of 350 bar and a maximum flow of 45 l/min. The 180 in the offered code identifies the upper spring-range value in that supplier offer; it is not a confirmed 180 bar factory preset or the maximum component pressure. The original standard-setting reference for this range is 90 bar. Confirm the actual delivered setting separately.

The VMPD circuit protects two hydraulic lines through independent relief branches discharging to one common tank connection. Connect the pressure lines to P/P1 and T to tank according to the original diagram. This is not the VAU crossed-discharge circuit. The factory table uses /000 as the spring-range placeholder; only the actually offered /180, /PP180 and /V180 executions selected here are represented.

The /PP factory option means arranged for a sealing cap. It does not by itself establish that a cap, tamper seal or calibrated setting is supplied. The series photograph may show the standard screw execution. The base-table mass is provided only as a reference; an exact mass and external envelope for this preparation are not independently established.

The body is zinc-plated steel with hardened and ground internal parts and standard BUNA-N seals. Base body dimensions are labelled as reference body dimensions; no adjustment-dependent overall envelope is inferred. Pressure/flow curves use oil at 50 °C and 30 cSt, which are curve reference conditions rather than an operating-temperature range. The local PDF retains the complete relevant original spread, including its ordering notes and spring table.
