Balls for ball valves

“We make particularly ‘round’ balls,” as Volz CEO Dr. Christoph Fleig likes to say. Users know only too well what that actually means: Volz balls are high-precision parts. The irregularities that inevitably result from vertical and horizontal turning are removed completely by us through meticulous polishing. High-precision balls simply ‘function’ better in applications. Yet another reason why Volz is the market leader and why our products set the benchmark in the ball valve industry. As our customer you not only benefit from premium products, but also from the maximum assurance afforded by our reputation.
