Pneumohydraulic Power Units

• 
• 

Fife Pneumohydraulic Power Units are specifically designed for web guiding, providing superior response and control with fully proportional corrective action. Power units are equipped with our exclusive four-way, spool-type servo valve to deliver unmatched sensitivity and stability in guiding applications for all types of materials, at any speed, under any load.
Completely self-contained, these Pneumohydraulic Power Units have a built-in regulated air system with a pump, filters, and regulator, as well as their own hydraulic reservoir, pump, filter and relief valve. External air is not required. Pneumohydraulic power units can be supplied with one, two or three servo valves on a single power unit. One power unit simultaneously, yet independently, can handle up to three separate guiding operations. For more than three guiding operations, a combination of power units may be used.

Key Features

Adjustable air pressure system provides for sensitivity adjustment and is matched to the controller, sensor, and guide structure
Compact, modular construction minimizes exterior tubing and provides maximum ease of servicing
Totally enclosed or explosion proof motors are available
Additional hydraulic ports are supplied on all units for use with optional Fife equipment
Provides superior response and control for any web guiding application
Exclusive spool-type servo valve for additional sensitivity and stability
For use with Fife anti-clogging air sensors
