The invention relates to a gas regulating unit with a valve basic body (11) which forms at least one gas inlet chamber and one gas outlet chamber, with a safety valve and with a main gas valve, wherein the safety valve and the main gas valve either open or close a gas flow from the gas inlet chamber into the gas outlet chamber. According to the invention, the valve basic body (11) comprises at least three parts, namely at least one plastic core (12), which defines the gas inlet chamber and the gas outlet chamber, and at least two metallic shells (13, 14), wherein a first metallic shell (13) encloses the plastic core (12) at least in sections on an upper side, and wherein a second metallic shell (14) encloses the plastic core (12) at least in sections on an underside, and wherein at least one diaphragm (15) is positioned between one of said metallic shells (14) and the plastic core (12), which at least one diaphragm (15) delimits in each case a drive chamber, in which a servopressure prevails, for the safety valve and/or the main gas valve.
