A pressure reducer assembly ( 10 ) with an inlet ( 26 ) and an outlet ( 78 ) adapted to be connected through a valve, having a fixed valve disc ( 42 ) and a valve seat body ( 62 ) cooperating with the valve disc ( 42 ), the valve seat body adapted to be set by a lifting member, which is exposed to the outlet pressure in a closing direction against the bias of a helical spring ( 50 ), wherein the inlet and the space ( 68 ) upstream of the valve seat ( 74 ) are in fluid communication through an axial bore hole ( 36 ) in a valve spindle ( 34 ) which is connected to the valve disc ( 42 ), the valve seat body ( 62 ) is pot shaped and moveably guided on the valve spindle ( 34 ), the helical spring ( 50 ) surrounds the valve spindle ( 34 ) coaxially to the bore hole ( 36 ) and acts between a spring abutment ( 38 ) provided at the valve spindle ( 34 ) and the pot shaped valve seat body ( 62 ).
