Materials: Commonly constructed from high-quality
plastics such as polypropylene or polyethylene, which offer
good chemical resistance to the various ingredients in
perfumes. Some premium valves may also incorporate metal parts,
like a metal nozzle or actuator, for added durability and a
more luxurious feel. The materials used are carefully selected
to ensure they do not react with the perfume and maintain its
integrity and scent.
Valve Structure: It typically consists of a valve stem,
a sealing mechanism, and a nozzle. The valve stem controls the
flow of the perfume from the bottle. The sealing mechanism,
often a rubber or silicone gasket, ensures a tight seal when
the valve is not in use, preventing leakage and evaporation of
the perfume. The nozzle is engineered to create a fine spray
pattern, usually with a small orifice that breaks the liquid
into tiny droplets.
