Claim:
A balanced pressure reducer for high-pressure gases, comprising: a body defining a high-pressure inlet and a low-pressure outlet; and a valve member ( 1 ) having a wide head ( 1 ′) designed to co-operate with a valve seat ( 6 ) of the body, said valve member ( 1 ) having a central body ( 2 ) made of a material that is hard and that withstands high pressures and covered at least in part with a first layer ( 3 ) of a rigid plastics material, said first layer ( 3 ) of a rigid plastics material covered at least in part with a second layer ( 5 ) of a less rigid plastics material, and wherein no contact between the less rigid second layer ( 5 ) and the central body ( 2 ) occurs in that zone of said valve member ( 1 ) which is subjected to the high pressures.
