Servo Valves

All new and reconditioned servo valves are backed by our two-year warranty

All new and reconditioned servo valves are backed by our two-year warranty

Our team of valve technicians is well trained in servo valve operation theory and functionality. Performing thousands of servo refurbishments every year, we are able to efficiently and accurately restore your units back to OEM specification.

Our goal is to recondition your valves and to use the pre-test findings to provide insight into your complete control system condition. Servo valve failure can often be the result of contamination, particulates, and degradation by-products in your hydraulic fluid.
