Need a control valve that can resist wear from abrasive slurry
(OP)
I need to find a control valve that can resist wear from abrasive slurry.
Currently the 6"X8" angle valve that is used for the application wears out every 5 months. We have experimented with ceramic lined 10"X8" angle valves, but they are easily broken, and very expensive. One valve costs US$23,000.00. Clarkeson valves were also tried, but the rubber continued to be eroded and blocked the lines.

It was a very nonspecific question.
One valve would be right for 30 psi flyash slurry (Pinch valve) , but an entirely different one would be necessary for cat-cracker letdown ( Angle, extreme hardness venturi tailpiece, such as Valtek Survivor). Yet another valve would be best for potato-peeler service.(Eccentric Rotary plug, shaft Upstream)
The only hint that the application might be high-temperature/pressure is that they are using a 6 x 8 angle valve and that ceramic has given them limited success.

You will have to check if it is right for your application, but I know they have severe service control valves, and they talk a lot about slurry experience in their sales literature.
