Product Detail :
Specifically designed for web guiding, Electrohydraulic Power Units are ideal for use with Fife’s full line of electronic sensors and signal controllers. These power units incorporate our exclusive 2-stage, high-resolution, spool-type servo valve to provide precise, proportional control regardless of material or load requirements.
Equipped with their own hydraulic reservoir, pump, filter, and relief valve, all standard models can be used for single, double, or triple guiding installations. By utilizing one or more servo valves, a single power unit simultaneously, yet independently, is capable of handling up to three separate guiding operations. For more than three, a combination of power units may be used
