ABSTRACT:
A low-noise control valve in which a noise-dampening element (9) is arranged inside of the valve housing (1) in the passageway of the medium. A built-in element, in which lamellas touching one another are arranged over the entire cross section of passage parallel to each other and parallel to the direction of flow serves as noise-dampening element. These lamellas exhibit a linear corrugation, with the directions of the corrugations proceeding obliquely with respect to the direction of flow and the directions of the corrugations of two adjacent lamellas at a time intersecting each other. Favorable sound level reductions are achieved in small installation dimensions. In upper valves, the built-in element can be arranged at the valve cone. In rotary cone valves, it can be designed as a valve seat.
