摘要:A valve is disclosed for heating, hot water or cooling systems having a connection pipe (11, 12) that leads to the train of pipes and to the consumer. A screw socket (13) receives a first closure piece (4) arranged in a hollow valve spindle (3). The first closure piece (4) forms throttle-like flow pre-setting means with a valve seat (14) in the housing (1). A second, double acting valve closure piece (5) that may be actuated from the outside against the pressure of a spring (6) by a regulator or the like is arranged in the hollow valve spindle (3) and slides in the valve spindle (3) against a corresponding valve seat (33). The hollow valve spindle (3) has two sections (3a, 3b) fitted into each other and a flat gasket (33) is sealingly arranged between both sections. The top end (51) of the second closure piece (5) acts against the inwardly projecting part of the flat gasket (33).
