British manufacturer of accurate and reliable electro-hydraulic servo valves
Over the last 40 years STAR have gone on to become one of the worlds leading manufacturers of industrial electro-hydraulic servo valves.
The key to our success is undoubtedly down to our innovative sapphire technology to eliminate ball glitch, and the implementation of modernised components to reduce contamination failures.
STAR Hydraulics was established in 1983 by Paul Shillam, who recognised the need for an independent servo valve repair facility following numerous requests from servo valve users whilst working at Dowty Hydraulics.
How we started...
Moog (who had given Dowty’s the licence to manufacture servo valves for Europe) initially supported Paul’s servo valve repair business by supplying STAR with unlimited spare parts to service and repair servo valves.
It is with thanks to Moog that STAR has grown into the successful British Manufacturing Company it is today. Without Moogs initial support of supplying STAR with spare parts, STAR Hydraulics Ltd would have never been born.
Unfortunately, Moog eventually changed their policy of supplying spare parts to independent servo valve repairers which effectively forced Paul to develop his own servo components and inevitably a complete range of servo valves. However, with years of service and repair work under his belt, Paul knew the pitfalls of earlier servo valve design, and came up with an innovative design, our famous sapphire technology to eliminate ball glitch and increase the life of the servo valve.
Sapphire Technology
STAR’s now famous Sapphire Technology has been proven to reduce ‘ball glitch’ – the term given to the effect on the valves performance due to ball wear. This in-house expertise enabled STAR to investigate the repeated failures of traditional valves and the wear on a particular component, a tiny steel ball, was found to be the main culprit. Star found that by replacing the steel ball with a Sapphire ball it vastly extended the life of the servo valve.
STAR’s range of servo valves have proven to be incredibly successful, coupled with hydraulic oil cleanliness & system maintenance training, plus the benefit of STAR’S Sapphire Technology, STAR servo valves are doing many billions of cycles without the need for repair.
