Battery production has increased in step with the demands of electric vehicles and renewable energy storage. Batteries are central to modern technologies and the transition to more sustainable energy systems.
Behind every battery cell lies a complex manufacturing process with demanding operating conditions. From raw material extraction and hydrometallurgical refining to slurry preparation, electrolyte production and recycling, valves are exposed to aggressive chemicals, abrasive slurries and high solids content. Corrosion resistance, abrasion control, process reliability and automation capability are essential to ensure consistent product quality and long service life.
GEMÜ provides a range of valves to support the entire battery lifecycle
GEMÜ provides a comprehensive portfolio of durable, chemical-resistant and digitally integrable valve, measurement and control solutions tailored to battery manufacturing. With in-house material expertise, GEMÜ help customers select optimal body and lining materials to maximise plant availability and system performance.
In hydrometallurgical processes, lined diaphragm valves like the pneumatically operated GEMÜ 620 offer reliable isolation and control. Hard rubber, PFA or PP linings provide excellent resistance to aggressive media.
For high-solids applications, deep-seated diaphragm valves like the GEMÜ 655 ensure dependable opening and closing.
Butterfly valves, including the GEMÜ R481 and GEMÜ 491, are suited for on/off duties and coarse solid flows, with chemical-resistant linings and coatings available.
For demanding control tasks in electrolyte production and recycling, the GEMÜ S40 enables precise, stable flow regulation for dosing organic solvents and handling carbonates - supporting compliance with stringent purity and safety requirements.
Across every stage of the battery lifecycle, GEMÜ delivers robust valve technology engineered for reliability in challenging process environments.
