Abstract
A fluid transfer valve (1) adapted to be cleaned by scraping, comprising a main fluid transfer section (2), a plurality of secondary fluid transfer sections distributed angularly about the axis (X--X) of the main section and disposed at equal distances from and at equal inclinations to this axis, and a rotary tubular elbow (4) connected at one end (4A) by a rotary coupling (5) to the main section and adapted, depending on its angular position about the axis of the main section, to have its other end (4B) aligned with any selected one (3A) of the secondary sections. The main and secondary sections and the rotary elbow have identical inside diameters, and the rotary elbow is part of a rotatable pipe closure element (7) comprising a ring (8) coaxial with the rotary coupling (4) through which said other end (4B) of the rotary elbow discharges and which at all times is in fluid-tight contact with the radially innermost edges of the secondary sections so as to close off all said secondary sections except said one selected secondary section.
