Aerosol valves are devices that release products in spray mode from containers under pressure.

The most common applications are in the fields of personal care, hair sprays, insecticides, households and food products.

Most aerosol valves are continuous spray mode. Metered dose aerosol valves are used for specific applications, particularly in the pharmaceutical sector and for air fresheners.

Coster production covers a complete range of aerosol valves that can meet any market requirement.

1” Valves


Continuous press-down valve

Press-down valves with continuous actuation: the pressure on the stem causes the opening of the actuating system.
They function both in the upright or upside-down position, according to the characteristics of the valve housing.
Given their versatility and the characteristics of their component parts, they can be utilized in most of the products available on the market.
Continuous press-down valve could be with or without vapour tap for upright use.

 

Applications:Cosmetics (spray and foam), Hosehold, Techinicals, water base products and highly ammable product.


Continuous Tilt-Action valve

Continuous actuation tilt-action valves: The valve opening is due by the horizontal movement of the stem.
Tilt action valve could be with or without vapour tap for upright use.

 

Applications: Cosmetics, Novelty (ex. Silly string) and technical ( ex. spray paint).


Venturi system continuous valve

Press-down valve with two vapour taps (Venturi system) for upright use.
The orifices dimensions, selected according to the gaseous or liquid phase, guarantee a perfect atomization of particles, thus producing a very fine and uniform spray that reduces the inflammable properties of the product.

 

Applications: Cosmetics, Household, water base products poor of propellant and highly inflammable product.


Continuous 360° valve

Press-down valves for 360° valve: Thanks to the insert and ball utilized on the housing, a 360° actuation is possible.
360° valves can be employed both with liquefied propellant and compressed gases.

 

Applications: Cosmetics, household and technical


Metered valve

Press-down 1” metered valve for upright use. Depending on the dosage, a specific amount of product is dispended at each actuation.

 

Applications: Pharmaceutical products and air fresheners


Continuous female valve

Press-down valve equipped with a fast-fill housing.
Generally used for products which have a tendency to dry up and block the stem. The actuator, which incorporates the stem, can be removed and cleaned easily.

 

Applications: Technical products (paints, adhesives and glues)
