Abrasive sintered dust and buildup cause double the wear on ball valves in pneumatic transfer vessels. In practice, standard faucets often last only 6 to 9 months. After that, they start to leak and no longer function properly.

Why wear is so high

Hard dust particles wear down the ball and seat—especially when switching against differential pressure. Deposits also prevent the valve from closing properly. As the delivery pressure increases, wear continues to increase.

Longer service life starts with the material

Engineered ceramics are extremely resistant to wear, heat, and corrosion. In a ceramic-lined ball valve, all parts that come into contact with the fluid are made of ceramic; the metal housing absorbs pressure and pipeline forces.

Our recommendation: the KGT ball valve

The Ball valve KGT combines the ceramic lining with a splined ballIts bearing design absorbs compressive forces and reduces stress on the seat. This minimizes wear—especially at higher pressures. It is already used in steel mills, mining, and the silicon industry to convey coal dust, quartz, carbide, silicon powder, and copper concentrate.
