Expertise in Valve Control for All Your Applications

Founded in 1985, Stonkus Hydraulic specializes in on site field service for automatic control valves and related equipment for municipal and industrial water and wastewater pumping applications. With extensive valve and control design experience, Stonkus Hydraulic provides on site field service and engineering in the Northeast and throughout the U.S. for many major valve and actuator manufacturers, as well as PM and emergency valve repairs for local municipal and industrial water and wastewater pumping facilities.

In 1995, Stonkus Hydraulic acquired Parco Engineering and now produces the full Parco product line. In addition, we build components and spare parts and provide retrofit and engineering services for all existing Parco projects.
