Oleodinamica Marchesini RS2-10L10 metric two-way ball valve

Oleodinamica Marchesini RS2-10L10 is a metric two-way ball valve identified by the full current factory related-product label RS2-10L10. Two independent supplier catalogues explicitly list this complete code as M16 x 1.5, DN10. No code was produced by appending a bore size to another article.

The current factory PDF labels its matching M16 x 1.5 / DN10 size row RS2-10L, while the factory webpage and the supplier order tables use RS2-10L10. That label difference is retained explicitly. The matching PDF row gives PN 500 bar, but this is kept as a source-row reference rather than an unqualified maximum-pressure filter for the differently labelled order code. No maximum-flow rating or unverified geometric revision is inferred.

The RS 2 family uses a zinc-plated steel body, ground and chromium-plated steel internals, and BUNA-N/POM seals. It closes flow with the lever at 90° and opens flow with the lever in line, according to the factory diagram. The image is a representative RS 2 family photograph; the exact metric connection follows the named order article and retained reference.

The local technical PDF retains the complete relevant original manufacturer spread, including the size table, option legend, hydraulic circuit and drawing. Neighbouring executions apply only to their identified rows. Oil temperature 50 °C and viscosity 30 cSt shown beside curves are reference conditions.
