Slurry Valves (Solids-Laden)
Abrasion governs — the ceiling is the wear mechanism, not the metal's thermal limit.
Abrasive solids — metal-seated ball valves with hardened trim are the usual answer inside this tool's scope. Knife-gate valves (the classic slurry valve) are deliberately outside the launch catalogue, so heavy slurry duty with a tight-shutoff requirement routes to engineering review.
Service flags: solids-laden, abrasive.
Materials at a glance
| Material | Rating | Up to |
|---|---|---|
| Carbon steel (ASTM A216 WCB) | Good | 120 °C |

Ratings: Excellent / Good / Conditional / Not recommended, from this site's boundary-and-medium data set. The manufacturer's data sheet for the specific product governs.
What drives the choice
- Metal-seated ball valves with hardened trim are the usual answer inside this tool's scope
- Hardened trim and seat overlay (Stellite-class) are the real requirement
- Knife-gate valves — the classic slurry valve — are deliberately outside the launch catalogue
Where the boundaries sit
- Heavy slurry duty with a tight-shutoff requirement routes to engineering review
