Oleodinamica Marchesini RS2-12L RS 2 M18 × 1.5 2-way ball valve

Oleodinamica Marchesini RS2-12L is an RS 2 2-way high-pressure ball valve with M18 × 1.5 connections, a factory PN rating of 500 bar and nominal bore DN 10 mm. Its listed mass is 0.616 kg. PN is the pressure designation printed for this article; the sheet does not provide a temperature-dependent pressure derating schedule.

The manual quarter-turn lever opens or isolates an oil line. Either A or P can face the supply: the original circuit shows flow blocked with the lever at 90 degrees and open with the lever in line. This is an isolation valve; no proportional metering characteristic or calibrated flow setting is assigned.

This is the DIN 2353 light-series tube connection for 12 mm outside-diameter tube, with an M18 × 1.5 metric connection thread. The tube diameter, metric thread and DN bore are different dimensions. The series photograph is representative and may show a BSP execution; use this exact metric row and connection detail in the PDF for selection.

The body is zinc-plated steel with ground, chromium-plated steel internal parts and standard BUNA-N/POM sealing elements. Installation dimension L is 44.4 mm, overall length L1 is 79.5 mm and lever dimension L2 is 110 mm. Check lever clearance and connection details against the original drawing. Fixing holes are an optional /FF execution, not a feature assumed for this base article.

The local PDF retains the complete relevant original article table, circuit and drawings. A manufacturer series image is shown. No temperature range, viscosity range or maximum flow is invented from the DN designation.
