Abstract

A diaphragm actuator (10, 40) for a control valve is shown including an actuator housing (12, 42), in which a diaphragm (14, 44) including a diaphragm disk (16, 46) is sealingly fitted thus forming a pressure chamber (20, 50), and furthermore at least one spring (24, 54) is provided which rests against the diaphragm disk (16, 46) and the actuator housing (12, 42), with the diaphragm disk (16, 46) being connected to a valve stem (22, 52) for actuating a valve body. At least two springs (26, 56) are provided and are disposed one after another in an axial direction between the actuator housing (12, 42) and the diaphragm disk (16, 46), with a spring seat element (28, 58) linearly guided by at least one linear guiding element (30, 60) being provided between the at least two springs (26, 56).
