A radiator valve comprises a housing (1) on which are arranged a pipe union (11) for connection to the radiator and a screw socket (13) for receiving the first closure piece (4), which is arranged on a hollow valve spindle (3). The first closure piece (4), together with a valve seat (33) in the housing (1), forms a choke-like preset device for the throughflow. To allow the line or radiator to be emptied through the hollow valve spindle (3), the hollow valve spindle (3) contains a second valve closure piece (5), which can be actuated from the outside against the force of a spring and moved forward from the outside with regard to a corresponding valve seat in the valve spindle (3). The second hollow valve closure piece (5) is double acting and can be moved, with its end (52) opposite the discharge valve seat (33), through the first valve closure piece (4) toward the housing valve seat (14). A controller (9) which acts on the second valve closure piece (4) can be placed on the valve. |
