Hydraulic valves that are electrically operated by proportional solenoids are classified as proportional valves. We offers the widest variety and range of proportional valves of any manufacturer, with performance proven in millions of operational hours.

Proportional rugged valves fit perfectly into automated electrohydraulic control applications. We also offer proportional directional control, proportional relief, proportional pressure reducing, proportional flow control, and proportional throttle valves.

And as an industry leader in the development of intelligent hydraulics, most  proportional and servo hydraulic valves have the option for integrated electronics or separate amplifiers
