20mm Metered Valve Offering Excellent Compatibility with Alcohol-Based Formulas
The 20mm metered valve is a precision aerosol dispensing system engineered to deliver consistent, pre-measured product volumes with each activation. This critical component ensures dosage accuracy through its precisely engineered chamber that fills with a specific liquid quantity (typically in microliters) before dispensing as a fine mist or stream. The system guarantees identical dosing from first to last use, making it essential for medical, pharmaceutical, and premium cosmetic applications.
