Many of STAR servo valves are manufactured with inlet orifices and feedback wire that include the Sapphire Technology. The benefit to the operator is that the traditional inlet and ball wear erosion problems that have been seen in the past are now just that, a thing of the past. These features enable STAR servo valves to deliver and maintain higher performance for extended periods without failure. This extended operational life results in reduced costs for the end user.
Sapphire Technology
- Incorporated into STAR designs since 1988
- Billions of cycles per service life
- Increased spool life due to spool rotation
- Ultra low coefficient of friction sapphire to steel
- Feedback mechanism unhindered by spool rotation
- Extended warranties available
