Pneumatic valves
Pneumatic spools frequently operate without lubrication.
BALINIT® MILUBIA coated high precision seal valves work reliably at poor lubrication conditions due to very low dry running friction.
BALIQ® CARBOS STAR is used for highly loaded precision valves, e.g for HPLC High Performance Liquid Chromatography valves, where hardness, toughness low friction and smooth surfaces are required.
