Improvements in the automatic purge valves for hot water installations, particularly for central heating installations, of the coupling type at one end of a purge pipe, characterized by being arranged coupled, inside a cylindrical bore made in the body of the valve, a prismatic plug, so that the purge conduits are determined uniformly distributed in the periphery of the plug, as said conduits are formed by the gaps formed between the faces of the plug and the hole.
