Slurry duty wears valves instead of corroding them. The questions are abrasion, particle hang-up and what 'tight shutoff' can honestly promise with solids in the line. For ordinary isolation on slurry lines the selector answers directly; the box below is a live answer for the reference duty.
One boundary is printed on purpose: heavy slurry service with a bubble-tight requirement is knife-gate territory, and knife gates are outside this tool's launch catalogue. If that is your duty, the page of record is the engineering-review channel, not a bent recommendation.
Typical duties
| Process slurry isolation | Slurry · 6–16 bar · ambient · DN100–300 |
|---|---|
| Tailings and discharge lines | Slurry · ≤16 bar · ambient · DN150–400 |
| Cyclone and pump suction/discharge | Slurry · 10–25 bar · ambient · DN80–250 |
16 bar · 40 °C · DN200 on Slurry (solids-laden liquid) (slurry): Ball Valve (floating / trunnion-mounted) · body Carbon steel (ASTM A216 WCB) · Class 150.
metal-seated ball valves with hardened trim are the standard answer for abrasive duty inside this tool's scope
/* r11 P3-6 (user-approved): the duty-specific caution (e.g. class utilisation) belongs ON the page, not only in the unlocked report — the last boilerplate line stays report-only */Watch: Your duty uses 83% of the Class 150 rating at this temperature (16 bar of 19.2 bar) — inside the published rating, but with little room for pressure surges. Ask the manufacturer to confirm, or consider the next class up.
What to watch
- The phase flag matters: solids-laden duties are screened differently from clean liquids — set the phase to slurry.
- Seat and body choices narrow fast with abrasion; the elimination record shows which types dropped out and why.
- Bubble-tight on heavy slurry: outside the catalogue — say so in the inquiry and we route it to a manufacturer by hand.
Where this connects on this site
- Slurry as a medium — what the ratings say
- Ball valves — where they survive slurry and where they do not
- Butterfly valves — the large-line option
Boundary rule: this page states single-point conclusions from the site's knowledge base — no supplier names, no matrices. The full 40-medium library lives in the selector.
