The invention relates to a disharge valve control installation meant for checking the tightness of assemblies and valves as well as of the discharge valve adjusting pressure. The installation consists of a nitrogen cylinder (2) connected to a pressure reducer (B) on which there are provided two pressure gauges (6 and 7), a high pressure connection (9) having a gauge (11) mounted thereon starts from said pressure reducer. After the gauge (11) the high pressure connection (9) is branched and connected to a pipeline (12).Some cocks (13 and 14) which separate the paths are mounted on this pipeline. Each of these paths is meant for feeding a valve (1) to be controlled. To this effect, from the cock (13 and 14) the pipeline (12) is connected through a nipple (15 or 16) to a support (17) wherein a taper thread subvalve (18) is screwed in. A reducing piece (19) in which the valve (1) is fastened is introduced into said subvalve.
