FIELD: valves production.
SUBSTANCE: invention relates to valves production and can be used in pipelines to block the medium reverse flow. Novelty of the invention is that the valve piston is installed in the cover inner cavity with the radial clearance. Communication of the “above” and “below” piston cavities is made through the series of through holes, at that, their area exceeds 50 % of the piston circle area. Above the piston from the cover bottom side flexible circular membrane with peripheral recesses is installed. In the cover, interacting with the piston adjustable stop is installed. Piston is connected to the swinging arm by means of two hinges lever.
EFFECT: technical result consists in increase in the valve reliability due to the piston and the flexible membrane damping properties.
