Heavy-Duty Metering Valve for Centralized Grease and Oil Lubrication Systems

Product Specification

Heavy-Duty Metering Valve for Centralized Grease and Oil Lubrication Systems with High-Pressure Tolerance

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.
