Title: CHANGEOVER VALVE
Abstract:
The invention relates to a changeover valve comprising a wall connection housing (1) with at least one inlet channel (11) and at least three outlet channels (12, 13, 14) which open into a valve seat (16) for receiving a valve upper part (2). The valve upper part (2) has a base piece (7) with at least three outlet openings (71) which can be connected to a respective outlet channel of the at least three outlet channels (12, 13, 14) via the valve seat (16). Furthermore, the valve upper part (2) has at least one feed (32) which is connected to the at least one inlet channel (11) and which can be connected to at least one of the at least three outlet openings (71) via a control disc (5) that can be rotated relative to a stationary inlet disc (6). The control disc (5) is in engagement with a spindle (4), by means of which the control disc can be rotated. The base piece (7) has at least one positioning pin (73) which engages into a positioning bore (17) arranged in the valve seat (16). The valve seat (16) is equipped with at least two positioning bores (17) for engaging with the at least one positioning pin (73) in different assembly positions of the valve upper part (2).
