The present invention relates to a fluid control valve comprising a valve housing (103) with a valve chamber (105) having at least two valve ports (111, 113, 115) distributed around a circumferential chamber wall (119) of the valve chamber (105), a valve rotor (107), which is rotatably arranged inside said valve chamber (105) and comprises at least one blocking portion (129) and a flow passage (133), wherein the valve rotor (107) is rotatable between a closed position, in which one of said at least two valve ports (111, 113, 115) is blocked by said blocking portion (129), and a first open position, in which the flow passage (133) of the valve rotor (107) allows fluid communication between said at least two valve ports (111, 113, 115), a groove arrangement (145) formed in the valve rotor (107), and a sealing member (143) which is configured to be received in the groove arrangement (145) and move together with the valve rotor (107). The sealing member (143) is formed as a single piece and comprises a sealing portion (147), which is configured to surround said blocking portion (129), and at least a first anchoring portion (149) projecting from one side (153) of said sealing portion (147) and being configured to fasten the sealing member (143) to the valve rotor (107). |
