Precision Aerosol Metering Valve for Spray Can Propellant and Product Dispensing with Consistent Delivery

Precision Aerosol Metering Valve for Spray Can Propellant and Product Dispensing with Consistent Delivery

Product Description:

This specialized 20mm metered valve is the heart of modern aerosol and spray can technology, engineered for the precise co-dispensing of liquid product and propellant. Designed to sit atop a standard 20mm canister, this precision aerosol metering valve is critical for delivering a consistent dose, puff, or spray of products like inhalers, air fresheners, lubricants, or culinary sprays. Its internal mechanism is finely tuned to create a perfect emulsion or gas-liquid mix upon actuation, ensuring the correct spray pattern, particle size, and volume is released every single time. The valve features a robust stem and a specially formulated gasket that maintains a perfect seal against high-pressure propellants like butane, propane, or compressed gases. For industries from pharmaceuticals to consumer goods, this valve guarantees product reliability, user satisfaction, and efficient use of both the active ingredient and the propellant, making it a key component in countless packaged products.

Bullet Points:

• Engineered for reliable performance in aerosol canisters with various propellants.

• Delivers a consistent and precise dose with every single actuation.

• Specialized seal formulation ensures long-term integrity and prevents propellant leakage.

• The metering chamber provides accurate volumetric control for the product concentrate.

• Compatible with both liquid gas and compressed gas propellant systems.

Specific Application Scenario
Used in a pharmaceutical factory to fill metered-dose inhalers (MDIs) for asthma medication. The valve must deliver an exact micro-dose of medication suspended in propellant, with life-saving accuracy and consistency.

Factory Production Floor

Production takes place in a high-purity, humidity-controlled environment. The assembly of the microscopic metering chamber and the installation of the specialized seals are fully automated to ensure absolute cleanliness and dimensional precision.

Packing and Transportation
Valves are bulk-packed in sterile, sealed bags within hermetically sealed drums to prevent any contamination or moisture absorption before they are delivered to the aerosol filling lines of consumer goods or pharmaceutical companies.

FAQ

• What is the dosage accuracy of this precision aerosol metering valve?

  • Dosage accuracy is typically within ±5% for standard models, with pharmaceutical-grade versions achieving ±2% or better.

• Is the valve compatible with all common propellants?

  • We offer different seal materials optimized for specific propellants (e.g., hydrocarbons, HFA, CO2, N2). Please specify your propellant for the correct version.

• Can the valve be used for both liquid and foam products?

  • The basic design is for sprays and doses. For foam, a different actuator and often a different valve design are required to create the foaming action.

• How does the valve prevent propellant leakage over time?

  • The combination of a precision-machined stem and a specially formulated, low-swell elastomer gasket creates a gas-tight seal that withstands internal pressure throughout the product's shelf life.

• Do you offer custom actuator heads (buttons)?

  • Yes, we provide a full range of standard and custom-designed actuator heads to create specific spray patterns, from fine mists to solid streams.

Future industry manufacturing complex spans an area of nearly 7,000 square meters. It incorporates six high-speed aerosol valve production lines and more than 30 special valve production lines.

Each year, Future industry aerosol can produce up to one billion aerosol valves. Our main products are air freshener aerosol valve, insecticide spray aerosol valve, butane gas aerosol valve, carburetor cleaner aerosol valve, ribbon spray aerosol valve, snow spray aerosol valve,paint spray aerosol valve, fluid spray aerosol valve, portable stove gas aerosol valve, 360 degree aerosol valve, powder spray aerosol vave. Also we have expanded the export market of aerosol metering valves, aerosol caps and aerosol cans.We have also built five standardized workshops to conduct different operations in order to meet the requirements of various customers to ensure we always meet production demands and timelines.

Production of the valve mounting cups is carried out in this workshop. We use a high-speed automatic stamping machine to transform high-quality steel plates into valve mounting cups. Due to the high degree of its automation, this equipment can help to reduce labor costs and increase production efficiency significantly.

In addition, we utilize an efficient machine that can automatically press an outer rubber ring into a valve mounting cup in order to provide superior sealing performance in the process of final assembly.

This workshop contains over 20 injection molding machines and three injection molding lines. Among them, our injection molding machines are used to produce a variety of accessories such as valve stems, valve chambers, actuators, and spray caps, etc.

Due to efficient automation, we require a very small number of staff to run these more than 20 injection molders. During the production process, our quality control inspectors are responsible for sampling and testing every batch of accessories. Additionally, our injection molding line has the capability to produce various sizes of dip tubes in automatic mode.

This workshop is used to assemble all kinds of accessories. It is equipped with automated assembly equipment to greatly increase production efficiency and provide our customers with enhanced profits.

After assembly is completed, our valves will be automatically counted and packed. We are proud to say we are one of the few companies in the industry that possess advanced abilities in product research and development. Every new product needs an innovative mold. For this reason we utilize high-precision wire cutting machines and machine tools that can form our molds into exquisite shapes.

We possess a wide range of technical production and R & D expertise
