K+S has the ability to repair and test many of the common manufacturers of servo valves found in today's industrial applications. Each valve's performance is initially checked upon arrival from the customer to determine the extent of damage. The valve is then inspected internally, cleaned and repaired at an environmentally controlled "clean station". At this stage, the valve is then load tested and plotted on a computerized diagnostic test stand for static and dynamic performance.

K+S has been awarded the sole OEM authorization to repair and distribute Star Servo Valves in the United States. Star designs and manufactures high quality electro-hydraulic servo valves and associated equipment. These Star valves are a low cost replacement alternative to some of the industries common manufacturers such as Moog, Pegasus, Atchley, Rexroth as well as others.
