FIELD: the valve is applicable in device for separation of multicomponent fluid media. ^ SUBSTANCE: the valve has a round fixed head with at least one main opening for connection with the flow of fluid medium, and at least one auxiliary opening. Thew fixed head includes at least one first environmental channel, an at least one concentric second channel, which respectively communicate with the main and auxiliary openings. Provision is made for a round rotary head, having at least one radial chamber, each of them having the first and second opening for connection to at least one from the first environmental channels and to one of the second auxiliary holes. The rotary head turns relative to the fixed head and channels and is hydraulically sealed. The step drive turns the rotary head for provision of mutual connection of the preliminarily determined main channels and auxiliary openings. The turning may be continuous in time or interrupted, depending on the respective process of flow of fluid media. ^ EFFECT: simplified design and conditions of mounting and servicing. ^ 38 cl 10 dwg |
