Sapphire Technology
Star Hydraulics” now well-known Sapphire Technology™ has been shown to reduce ”ball glitch”—the term used to describe the effect on valve performance caused by wear on the ball. This expertise at Star Hydraulics has made it possible to study the recurring failures in traditional valves and the wear on a specific component—a small steel ball—which turned out to be the primary cause of failure. Star Hydraulics found that replacing the steel ball with a Sapphire ball significantly extended the service life of the servo valve.
Long shelf life
Star Hydraulics’ range of servo valves has proven to be extremely successful. Star’s Sapphire Technology™, combined with training for our customers on the importance of hydraulic oil cleanliness and system maintenance, enables Star servo valves to operate for many billions of cycles without requiring repair.
