Abstract
Abstract A six-way deviator valve for liquids, of the type comprising two three-way valves in the same housing separated by a dividing baffle, each of the three-way valves possessing one permanently open nozzle for connection to a main pipe, and two internally closable nozzles for connection to secondary pipes, the two closable nozzles being closed by a suitable obturator element, is described. Each of the two obturator elements comprises faces mounted on support elements and arranged to rest on corresponding seats formed on the internal extremities of the two closable nozzles, the obturator element also being rotatable about a fixed axis of rotation and rotated by a rotating drive spindle located inside said housing, the drive spindle being rotated by external means by way of linkages.
