In a pressure-reducing arrangement with a pressure-reducing valve (16) and a pressure-indicating device (18) for indicating the outlet pressure, the pressure-indicating device (18) contains a spring-loaded piston (156) acted upon by the outlet pressure of the pressure-reducing arrangement, an indicating member (166) rotatable about the axis of the piston (156), and a coarse-threaded guide (172, 174) by means of which a linear motion of the piston (156) can be converted into a rotary motion of the indicating member (166). The indicating member (166) is a rotatably mounted disc (168) with a central shaft (170). The pressure-reducing arrangement contains a pipe connection piece (10). On one side, the pipe connection piece (10) has a collar (54) into which is inserted a filter cup (12), a collar (62) which is coaxial with the collar (54) and which holds a screen (14) centred, and an opening (68), which is arranged coaxially within the collar (62) and is connected to the outlet connection piece (22). The pressure-reducing valve (16) is arranged coaxially within the screen or filter (14) and its valve-seat body (70) is held in sealing fashion in the opening (68) of the pipe connection piece (10). A cylinder (150), in which the piston (156) of the pressure-indicating device (18) is guided, is formed integrally on the pipe connection piece (10). <IMAGE>
