Structural Testing

K+S Services works with Sapphire Technology, allowing feedback systems for structural testing to remain in service for longer in challenging environments.

K+S ensures your machinery is capable of accurately testing and evaluating structural strength.

K+S is the only USA Distributor for Star Hydraulics. Star Hydraulics designs and manufactures durable, high quality Electro-Hydraulic Servo Valves as well as ancillary equipment and have been doing so for over 40 years.

Sapphire Technology enables the feedback mechanism to remain in service longer in challenging environments, well in excess of 10^8 cycles and built to withstand skydrols, water glycos and phosphates esters, as well as extreme temperatures ranging from -45 degrees Celsius to well above 145 degrees Celsius.
