Pneumatically operated ball valve

  • Description
  • Features
  • Technical specifications

The GEMÜ B44 3-piece 2/2-way metal ball valve is pneumatically operated. The 1.4435 stainless steel alloy material composition used for the ball valve body (compliant with 316L) with a low delta ferrite proportion of < 3% is particularly suited to applications in the supply sector for the pharmaceutical, foodstuffs processing and biotechnology (such as water treatment and sterile steam generation) industries. Only those plastics which are compliant with FDA, USP Class VI and Regulation (EU) No.10/2011 are used for the seals.

Valve solutions for mixing electrode slurries

The first step in the manufacture of lithium-ion battery cells is to mix the electrode slurries, which are then applied to the electrode foils (anode/cathode) as a layer in the next step. The slurry comprises a mixture of active materials, solvents, binders and additives. When mixing slurry, it is particularly important to feed in the different components in precisely the correct quantities. GEMÜ has the appropriate valves, measurement and control systems to ensure the process reliability of this manufacturing step. Find out more about the slurry mixing process and how GEMÜ supports you with expert solutions in this application flyer.
