\u2139 Flowrates supports the battery recycling sector in addressing its technical challenges.<\/p>\n

As part of a project dedicated to electric vehicle battery recycling, we supplied a custom-designed knife gate valve with a 1200 x 1200 mm clear opening.<\/p>\n

This project involved several specific constraints identified by our client:
\n– Air-tightness requirement, as lithium reacts strongly upon contact with oxygen.
\n\u2013 Vibrations, metallic particles, and potentially corrosive conditions under the hopper, due to battery shredding.
\n\u2013 ATEX-classified zone, requiring compliant components.
\n\u2013 High operating frequency, demanding robust mechanics designed for long-term reliability.<\/p>\n

Implemented solutions:
\n\u2013 Valve body fully machined from solid block to ensure mechanical stability.
\n\u2013 Antistatic PTFE seals, ATEX-compliant.
\n\u2013 Precision-machined sealing system, manufactured by our partner Ivaltec, ensuring resistance to vibrations.
\n\u2013 Integration of a bidirectional sealing system.
\n\u2013 Festo linear actuator, selected for its ability to withstand thrust constraints and frequent operations without buckling.<\/p>\n

Validation test:
\nA bubble-tight test was carried out to validate the overall performance \u2014 inspired by the best practices in fluid mechanics! <\/p>\n

At Flowrates, we intervene early in such projects, supporting technical teams from design to manufacturing follow-up, and ensuring reliable equipment delivery.<\/p>\n
