Pre-selection for industrial process valves

Media Guides

Twelve media buyers actually search for — the properties that drive the choice, the materials that carry it, and the boundaries. The full 40-medium library lives in the selector.

A materials-and-temperature duty before anything else.

A certification requirement, not an alloy upgrade.

Abrasion governs — the ceiling is the wear mechanism, not the metal's thermal limit.

Chloride pitting is the governing risk — 316L is marginal.

Concentrated acid passivates carbon steel — with strict conditions attached.

One of the hardest common media — most metals lose.

An oxidising acid — the passivation rules invert.

Caustic embrittlement, not corrosion rate, is the binding constraint.

Oxidiser and chloride carrier at once — lined valves are the workhorse.

Easy when clean and sweet — the sulphur content changes the document.

Benign to most metals — the seal material is the real question.

An oxidiser that passivates the right stainless and attacks the wrong one.
