Web Printing Controls 805-780-20 Ink Key Actuator

The Web Printing Controls 805-780-20 Ink Key Actuator is an electromechanical servo actuator that precisely positions ink fountain keys on web offset presses. It converts electronic adjustment commands from the WPC 816-313-00 ink control system into accurate, rotary-to-linear movement to regulate ink film thickness across the printed web. Commonly installed on commercial web offset newspaper, publication, and heat-set presses that use Web Printing Controls automation, this actuator is designed for OEM replacement, press maintenance, retrofit projects, and restoration of automatic ink control systems. Built with an industrial metal housing, it provides automatic ink key positioning and precise ink metering as part of the Web Printing Controls ink control systems. Applications center on automatic ink fountain key adjustment to ensure consistent ink distribution across each printing unit, compatible with Web Offset Printing Presses and installation as an individual ink fountain key assembly. Common replacements include Web Printing Controls 805-780-60, 805-780-40, and 805-780-80.
