FIELD: aerosol equipment.
SUBSTANCE: aerosol valve unit has the valve frame and the valve body with the lower part, intermediate part and rod. When the valve is closed, the gasket in the rod groove packs at least one nozzle in the valve rod. The valve frame has the lower wall with the central hole for the lower part of the valve body, to stabilise the vertically acting valve, and the multiple holes for product passage localised around the central hole. The run limiting valve body surface prevents the complete exit of the gasket from the groove in valve activation. When the valve activation is stopped, it is returned to the closed position by the gasket which impacts the rod groove, and by the product effecting the lower part of the valve body and lower part of the intermediate part of the valve body. The aerosol valve unit opens readily and doesn't need the return spring.
EFFECT: invention relates to valves for dispensing ductile and semiductile products from aerosol containers.
