Metered Aerosol Valves: Precision Dispensing for Aerosol Applications
INTRODUCTION
Metered aerosol valves are specialized dispensing systems designed to deliver a consistent, pre-measured dose of product with each spray. These valves are critical in industries where dosage accuracy, safety, and repeatability are paramountsuch as pharmaceuticals, high-end cosmetics, and industrial applications.
In this article, we’ll explore:
✔ How metered aerosol valves work
✔ Key benefits over standard valves
Unlike continuous spray valves, metered-dose valves (MDIs) release a fixed volume of product per actuation. The mechanism includes:
Dosing Chamber – Holds a precise amount of product before release.
Stem & Spring System – Ensures consistent valve reset after each spray.
Actuator – Controls spray pattern
Gasket/Seal – Prevents leakage between doses.
When the user presses the actuator, the valve opens, releasing the exact same dose every time. This is crucial for applications like asthma inhalers, medical sprays, and luxury fragrances, where over- or under-dosing is unacceptable.
✅ Precision Dosing – Delivers the same volume per spray (e.g., 50µL, 100µL).
✅ Reduced Waste – Prevents over-spraying, saving product and cost.
✅ Regulatory Compliance – Meets strict FDA, EP, and ISO standards for pharmaceuticals.
✅ Enhanced Safety – Critical for drug delivery, pesticides, and chemicals.
✅ Improved User Experience – Consistent performance in cosmetics and personal care.
