Valves The principal functionality with the valve is to control the flow in the therapeutic agent and propellant from the container. The spray traits in the aerosol are motivated by orifice dimension, amount, and placement. Most aerosol valves deliver for ongoing spray Procedure and therefore are applied on most topical items. Nonetheless, pharmaceutical solutions for oral or nasal inhalation generally employ metered-dose valves that need to deliver a uniform quantity of spray upon Just about every valve activation.

) as well as the refrigerated propellant are measured into open up containers (usually chilled). The valve-actuator assembly is then crimped on to the container to sort a force-limited seal. In the interval between propellant addition and crimping, ample volatilization of propellant occurs to displace air through the container. While in the “stress-fill” process, the concentrate is positioned during the container, here and either the propellant is forced stressed through the valve orifice after the valve is sealed, or maybe the propellant is difference between syrups and suspensions allowed to move beneath the valve cap and afterwards the valve assembly is sealed (“underneath-the-cap” filling).
