The aluminum body keeps it lightweight and corrosion-resistant, while the Viton (FKM) disc seal handles a wide range of chemicals and temperatures. Its detent mechanism provides positive stops so the valve stays firmly open or closed during transport. You would replace it if the disc seal wears, the body becomes damaged, or the detent mechanism no longer holds reliably.
