Abstract: The invention relates to a controllable two-way valve (1), in which a valve rod (3) is connected in a permanent manner to at least two valve members (4, 5, 6, 24, 25; 39, 40), the valve rod (3) being actuated by means of an actuator (2). The housing (7) comprises an inlet (8; 4) or outlet and two corresponding outlets (9; 32; 42), (10; 28; 43) or inlets. According to the invention, the two valve members (4, 5, 6; 24, 25; 39, 40) correspond with at least two valve seats (12, 17, 22; 29, 37, 38; 46, 47) and the two or more valve members (4, 5, 6; 24, 25; 39, 40) have three control surfaces (11, 13, 18; 26, 27, 31; 44, 45, 48). The invention thus provides a dirt-resistant valve, which is easy to operate, has fixed valve members and does not require additional equipment. Said valve permits both the inlet to be completely blocked and the two outlets to be controlled independently of one another.
