By their mass, the cast -iron valve is larger, respectively, its installation is associated with certain difficulties. The ball crane has a smallest capacity, the same can be said about dimensions and weight. Naturally, it is much more convenient to use an economical and durable “ball” than a bulky and unreliable valve. In addition, the crane has several fastening options and a high overlap speed, which adds advantages to it.
