Aerosol valves may not be the first thing that comes to mind when you think of everyday products, but they play a key role in many aspects of our lives. These unsung heroes are responsible for supplying a wide range of aerosol products, from spray paint to cars, cosmetics to household cleaners and even medical inhalers and are highly successful devices in the industry. In this article we take a deep dive into the world of aerosol valves, Choose the right aerosol valve for yourself based on its working methods, industry applications, specifications, etc.

What is an aerosol valve?

Aerosol valves are small but essential and critical components that control the release of liquids, gases or fine solids in the form of mist or spray. Commonly used in spray paints, deodorants, air fresheners, lubricants, and other products. They consist of several key components, including the stem, housing, dip tube, and actuator. These small but critical pieces of equipment play a key role in the controlled release of liquids, gases or fine solids from pressurized vessels, with components working in harmony to deliver product in a consistent and user-friendly manner. Because the valve will spray the product evenly, all controlled by the user’s hands, among other advantages. They have been a popular product in industry, household appliances and other industries from the 1950s to the present

How the aerosol valve works

An Aerosol Valve is a device used to release an aerosol or aerosol product, usually included in a pressure container, such as a spray can or aerosol bottle. The working principle of these valves is based on a simple physical process involving pressure and fluid flow. Here’s how an aerosol valve works:

  1. Liquid or gas in the container: Aerosol products usually include a mixture of liquid, gas or solid particles. These products are contained in a sealed container, and there is usually a certain amount of pressure within the container to push the product to the valve.
  2. Valve structure: Aerosol valves usually consist of several important parts, including valve head (actuator), valve core (valve stem), sealing gasket (gasket or O-ring) and nozzle. The valve head is the part that is in contact with the user, the valve core is a part with a switch function, the sealing gasket is used to prevent leakage, and the nozzle controls the spray pattern of the liquid.
  3. Pressure release: When the user presses or triggers the valve head (such as a spray button), the valve core opens, allowing the pressure in the container to be released. This released pressure pushes the liquid or gas through the nozzle and into the atmosphere.
  4. Liquid dispersion: Through the specific design and structure of the nozzle, the liquid or gas is dispersed into tiny particles or aerosol in a specific way. This dispersion is usually uniform, producing a controlled, fine spray.
  5. User control: Users can control the intensity and direction of the spray by operating the valve head. This provides precise product application and ease of use.
  6. Sealing: The sealing gasket inside the valve ensures that the product will not leak or evaporate when not in use. This helps maintain product freshness and prevent waste.

Aerosol valve applications:

There are many types of aerosol valves, which play a key role in many industries and products; they can be used in almost every industry, and they are a necessary part of many products on the market. Since it involves so many industries, it is impossible to list them all. Here are some common main application areas in the industry:

  1. Personal care products: The cosmetics and personal care products industries often use aerosol valves. They are used in aerosol perfumes, deodorants, hair gels, shaving foams and other products. The aerosol valve provides an even, precisely dispersed spray, making the product easy to use.
  2. Household products: Household cleaning products, air fresheners, insecticides, etc. also often use aerosol valves to accurately spray and distribute the products, making home work more convenient.
  3. Pharmaceutical products: Aerosol valves are used in the pharmaceutical field to make inhalers to treat asthma and other respiratory diseases. These valves ensure that medications are released in accurate doses and in a controlled manner to meet the patient’s needs.
  4. Automotive products: Lubricant, brake cleaner, tire inflator and other products usually use aerosol valves to accurately apply and distribute the product to meet the needs of car maintenance.
  5. Food industry: There are also some products using aerosol valves in the food industry, such as cooking spray oil, edible oil sprayers and whipped cream sprayers.

Once you understand the general specifications of an aerosol valve application, you can select the correct market technology for your needs.

What are aerosol valve specifications

Aerosol valve specifications refer to the specific technical parameters and performance characteristics of an aerosol valve. These specifications are usually provided by manufacturers so that consumers and businesses can choose an aerosol valve that suits their needs. Aerosol valve specifications typically include the following:

  1. Valve types: Describe the main types of aerosol valves, such as spray valves, foam valves, dispensing valves, etc.
  2. Capacity: The volume of liquid or gas released by each spray of the aerosol valve, usually in milliliters or milliliters per second.
  3. Caliber: The size of the valve head (actuator), usually in millimeters, which affects the dispersion and injection angle of the spray.
  4. Spray distance: The farthest distance the aerosol valve can spray liquid or gas, usually in millimeters or feet.
  5. Spray mode: Describe the spray mode provided by the aerosol valve, such as uniform spray, fine mist, atomization, continuous spray, spot coating, etc.
  6. Material: Describe the material of the internal and external parts of the valve, including metal, plastic, rubber or other suitable materials. This is because material selection may be affected by the compatibility and chemical properties of the liquid or gaseous product.
  7. Spray angle: Describe the spray angle of the aerosol valve, such as horizontal, vertical, fan-shaped, etc.
  8. Pressure requirements: Describe the pressure range required by the aerosol valve to ensure proper spraying of liquid or gas.

These specifications are important in selecting the appropriate aerosol valve because different applications require different types and capabilities of aerosol valves. Consumers and businesses often select aerosol valves based on their product’s specific needs, use environment and performance requirements to ensure optimal performance and reliability. Manufacturers usually provide detailed aerosol valve specification information in product documentation or official websites to help customers make the right choice.

How to Select Aerosol Stems and Stem Gasket Types

Remember: the valve stem and stem gasket are important parts of the aerosol as they form the seal of the valve and thus ensure product quality. Using the wrong type of gasket or stem will result in shrinkage, expansion or poor sealing, resulting in loss of product. Before choosing these accessories, you must know which industries your products are used in. The success or failure of the project also has a certain relationship with the manufacturer. . Below I will provide some suggestions to help you select the appropriate aerosol stem and stem gasket:

  1. Understand the product type: First, you must clarify the nature of your aerosol product. Different types of products may require different stems and gaskets to ensure proper dispersion and spraying of the product. For example, personal care products, chemicals, or cleaning products may require different stems and gaskets.
  2. Determine the valve type: Different types of aerosol valves may have different stem and gasket requirements. For example, single-use valves may require specially designed stems and gaskets, while reusable valves may require more durable components.
  3. Consider product consistency and viscosity: Product consistency and viscosity will affect stem and gasket selection. Thicker products may require more wear-resistant stems and gaskets to handle high levels of wear.
  4. Consider temperature and pressure: The environment in which aerosol products are used can affect the performance of valve stems and gaskets. High temperature or high pressure conditions may require special materials and designs of stems and gaskets to ensure safe and reliable operation.
  5. Material selection: Valve stems and gaskets are usually made of plastic, metal, rubber or other materials. When selecting materials consider the product’s composition and compatibility with it. For example, some chemicals may be compatible with specific materials, while other materials may not be resistant.
  6. Compatibility and Standards: Make sure the selected stem and gasket are compatible with the aerosol valve you are using and comply with relevant standards and regulations.
  7.
