A discharge valve for a blood pressure measuring device or the like, comprising a valve casing the interior of which is in fluid communication with an inflatable cuff and a pressure measuring device (gauge) and an air outlet leading to a flat valve seat located on the exterior of the valve casing, where the air outlet is closed off by an elastic (rubber) annular valve washer which is disposed with its central hole over a stud-shaped guide member and which has a ring-shaped control element on its outer edge, the control element being used for removing, i.e., deflecting away, the washer from the valve seat. By manual manipulation of the control element, air pressure is released with fine control from the inflated cuff.
