Abstract
An improved check valve for compressed gases, constituted by a cylindrical body, with a lower hole provided with the thread for adaptation to the compressed gas boiler and upper part closed by a threaded plug that allows to properly check the interior. In the central area of the cylindrical body, there are two perpendicular conduits of communication with the interior of the valves, one of them, the one with the largest diameter, is the one that connects with the compressor element of the gas, while the other allows the connection with a valve. That automatically causes the purge of the compressed air existing between the check valve and the compressor, which facilitates the work of the compressor.
