FIELD: machine building.
SUBSTANCE: invention represents valve device (1) for container (100) for loading/unloading carbonated beverages, comprising main valve (1) connected to such container (100) by means of connecting element (101). Housing of main valve (1) includes ports for loading and unloading (10) of carbonated beverages into/from container (100), as well as sealing element (2) located on unloading port (10), elastic element (3) interacting with such sealing element (2), beverage unloading means located inside said main valve (1). There are also pressure control means (5, 40, 41) for monitoring the pressure below the boundary value inside container (100). Valve device is characterized by that unloading means (4) and said pressure control means (5, 40, 41) include single element (4, 40, 41), installed in a movable way inside said valve device (1), their arrangement such that unloading device (4) is movable from the first position, where it interacts with sealing element (2) for compacting carbonated beverages inside container (100), to second position where gas exits container (100) with preset container gas boundary value (100).
EFFECT: disclosed is a valve mechanism for filling and emptying of pressurized pet tanks.
