A pressure reducer has a housing with inlet and outlet sockets, a partition between said inlet and outlet sockets, and an accommodation socket. The partition defines an aperture aligned with the accommodation socket. A pressure reducer insert is inserted into the accommodation socket and the aperture. The pressure reducer insert has a tapering, funnel-like insert housing, a valve seat, and webs for connecting the insert housing with a valve seat sealingly mounted in the aperture. A regulating diaphragm closes the open end to define a controlled pressure chamber which communicates with an outlet chamber. A cap encloses a biased helical spring and a bias setting threaded spindle rotatably mounted in the cap. A setting knob is axially movable between a first position non-rotatably coupled with the cap, and a second position rotatable relative to the cap where rotation of the knob rotates the bias setting spindle and adjusts the pressure setting.
