20mm Metered Dose Aerosol Valve for Alcohol-Based Formulas

The 20mm metered valve is a precision dosing aerosol component designed to release a consistent, pre-measured volume with every press. It helps brands and manufacturers control dosing accuracy while supporting alcohol-based formulations and reliable dispensing.

Built around a calibrated metering chamber, this 20mm metered valve fills to a set volume and then dispenses on actuation as a fine mist or stream. The design supports repeatable output from first use to last use, helping maintain consistent user experience and controlled delivery. With a 20mm crimp specification, it is made for secure container attachment and stable sealing. Material selection is described for compatibility with ethanol, sterile solutions, and a range of propellants. It can be used with traditional aerosols and Bag-on-Valve (BOV) systems, and is also described as suitable for solutions, suspensions, and creams.
