Aerospace, Construction & Farm Equipment Hydraulic Components

Quality of your hydraulic system plays a vital role in the performance and reliability of your products. A critical factor to this performance is the fit between the spool and the valve bore. Achieving optimal clearance between these two components results in improved performance, lower propensity for leaking, better hysteresis, fewer repairs and increased reliability.

Engis Single-Pass Bore Finishing, and Multi-Stroke Honing technologies deliver superior-fitting bores. We have over 35 years of focused experience in the development of Single-Pass technology, specifically for hydraulic applications.
