The invention relates to a valve (1) for an indoor temperature regulating system, e.g. a Heating and Ventilating Air Condition (HVAC) system or liquid radiator heating system. The valve (1) comprises a fixed valve housing (2) provided with at least six valve connections (201-206, 205', 206') and a valve selector (3) for switching between providing a circulating flow from a first fluid source F1and a second fluid source F2 thereby enabling fluid of different temperatures to a treatment unit (T). The valve selector (3) comprises a disc plate (67) provided with openings (601-606, 605', 607'', 609, 610) and the valve main body (4) is provided with valve openings (401-406, 402', 404', 405', 406', 402'', 404'') being connected via channels to said valve connections (201-206, 205', 206'). The valve selector (3) and valve main body (4) are designed such that they may slide against each other. In the first mode are valve openings in register with lower disc plate openings such that two flow paths connecting the first fluid source F1 with the treatment unit T are enabled and in the second mode are valve openings in register with lower disc plate openings such that two flow paths connecting the first fluid source F1 with the treatment unit T are enabled. The switching between the first and second mode may be done by a turning motion of the moveable valve selector (3) relative the valve housing (2). |
