Abstract

A diaphragm controlled differential pressure control valve, in particular for hot water heating systems, having a controller housing (1) in which a valve plate (3) which interacts with a valve seat (2) is connected via a piston rod (4), which is guided in a sealed manner on the controller housing (1), to a diaphragm (20), which is clamped between diaphragm plates (19, 21), which divides a housing chamber into a negative-pressure chamber on the valve-seat side and a positive-pressure chamber, and which is stressed by an adjustable spring arrangement (11) in the direction away from the valve seat (2). In order to construct the spring arrangement (11) in the interior of the controller housing (1), a hollow hub (25, 26) is formed from the diaphragm plate (21) on the valve-seat side, or by the two diaphragm plates (19, 21), in which hollow hub (25, 26) the spring arrangement (11) is supported on the diaphragm plate (19) averted from the valve seat (2) and on a spring plate (10) which is screwed onto the threaded part (121) of an adjusting screw spindle (12) which is guided out from the controller housing in a sealed manner through the base wall (18) of the controller housing (1) averted from the valve seat (2) and which spring plate (10) is held in a rotationally fixed manner on a fork (13) which runs through the spring arrangement (11), passes in a displaceable manner through the spring plate (10) and is fixed to the housing. <IMAGE>
