摘要

The sanitary diverter valve (70) is for use in a drying system or powder conveying system including conveying lines and a purge line of a purge arrangement. The sanitary diverter valve comprises a valve housing (71) with a number of openings (72, 73, 74) configured to be connected to respective lines of the system. The valve housing (71) is substantially cylindrical and includes a first opening (72), a second opening (73) and a third opening (74). Furthermore, the diverter valve (70) comprises a rotatable diversion member (75) provided with a flow channel (76) having a first end (76a) and a second end (76b), an open space (77) being defined between the valve housing (71) and the rotatable diversion member (75). The rotatable diversion member (75) is configured to be rotated between a first position and a second position to allow that fluid communication is selectively provided between the first opening (72) and the third opening (74) and between the first opening (72) and the second opening (73) of the valve housing (71)
