Slurry Fluid Material Seats.

(OP)
I would like to know which material seats, in a valve, can be used in slurry fluid at 20ºC @ 720psi.

RE: Slurry Fluid Material Seats.

Glass reinforced ptfe is good for slurry service.  Although I've never used at those pressures.

RE: Slurry Fluid Material Seats.

We have built some valve seats using tungsten carbide for downhole oil well applications.

We suggested TiCN or Sic/Al2O3 as well but customer went with safest course.  

WC Rings were about 6” across as well as thin and flat so controlling thermal stress during brazing was an issue.  

Last I heard they ran about 6 months compared to three weeks for previous material.

RE: Slurry Fluid Material Seats.

Before I used SiC or AL2O3 I would try TTZ.  The toughened zirconia grades are not as hard, but they are very tough and this often allows them to resist wear.
