FIELD: machine building.
SUBSTANCE: valve consists of seat, shut-off element and damper. The shut-off element interacts with the valve seat and travels in the valve case for preliminary specified distance. The damper effects the shut-off element at least at part of its displacement. Damper (22) contains at least one element (23, 24) made out of elastomer material. This element (23, 24) can be compressed between the first stop (16) connected with the shut-off element and the second stop (28) connected with case (11) of the valve. The said element (23, 24) at least on one side adjoins surface (26, 27) with a specified profile in the direction perpendicular to shut-off element travel; this profile facilitates deflection of the said surface from plane perpendicular to the direction of shut-off element travel.
EFFECT: accuracy of control over flow of fluid even at low consumption.
