Ball valve - 15FF (Green)
Ball valves in indoor water supply networks have now almost completely replaced cork cone cranes due to their reliability and durability, which is an order of magnitude higher than that of older designs. The main thing that ensures the reliability of ball valves as shut–off valves in comparison with valves with a cone plug is that the working medium (water) with hard abrasive particles is passed in the ball valve past the sealed surfaces through the hole in the spherical valve, into the passage, and in the tap with a cone plug – around it.
