York, UK-based Salford Valve Co. Ltd. (Salvalco) has refined the execution of its existing Eco-Valve design by making changes to the three-piece valve system.
Following research in the laboratory with customer bulk formulations, several small adjustments to the liquid, gas flow channels and hole positions were made so that the Eco-Valve bubbly flow/effervescent effect is maximized for use with more complex formulations, for example those containing powders.
During the process of making these changes, the company also took the opportunity to optimize the Eco-Valve to help the aerosol filling process, improving the resilience of the valve to ensure high speed filling line efficiencies are maintained.
To compliment the Eco-Valve, Salvalco also industrialized new mechanical break-up (MBU) inserts to deliver desired customer spray characteristics. According to the company, this is especially important when using nitrogen instead of LPG propellant.
Benefits includes a better spray quality and atomization; greater consistency throughout the life of the can resulting in an enhanced spray quality from beginning to end; more compatibility with different formulations, including use with more organic and natural formulations that are not normally compatible with LPG propellant; a stronger and more resilient valve overall with strong durability on filling lines; the same sustainability benefits through the reduction of volatile organic compounds (VOCs) and hydrocarbons; and an overall cost- effective solution, eliminating the need for more expensive alternatives.
