All wear components (gate, seat plate and bore liner) on this SlurryFlo control valve are made of diamond ground Sintered Tungsten Carbide. Our proprietary grade has an HRA hardness of 89 and a compressive strength of 490,000 PSI. We also use an elevated amount of Nickel as our binder, which provides excellent corrosion resistance and toughness. Furthermore, the average grain size is 1-3 micron, resulting in a trim that resists impact and abrasion incredibly well. SlurryFlo’s carbide is used extensively in the harshest of mining applications.
