Slurry Valve Tightness
Slurry Valve Tightness
(OP)
Hello all!
What's the best material combination (metal/metal, metal/polymer, ???/????) of materials to assure tightness in high pressure and high abrasive applications such as the valves in a positive displacement pump for bauxite slurry transport?
Thanks all!

Another way to approach difficult applications, instead of stressing over the correct material/material combination, may be to go with 2 or more valves in series. If one valve won't hold, try 2 ... and so on.
Material selection and appropriateness is important. But, if in doubt ...

RE: Slurry Valve Tightness
People pump similar slurries commercially on a daily basis, often against quite high pressures, and the good pump manufacturers do tend to learn what works and what doesn't. Their distributors, on the other hand, can seldom be relied upon to provide this information. And of course if you hard spec something, that's what you'll be offered, regardless how well it is likely to work.
