Ballhead Hydraulic Servo Actuator Type 2231-1GH

The REGULATEURS EUROPA 2231 actuator is a proportional actuator in which the output shaft position is proportional to the electric input signal. Included within the same unit is a conventional ballhead hydraulic governor providing engine speed control in the case of an electronics failure. The essential part of the 2231 actuator is the high response electric servo-mechanism, which overrides the ballhead pilot valve. In the event of a power failure or controller fault, the governor system will fail to the ballhead mode. The actuator offers work outputs of 8, 15, 25, 34 or 40 ft·lbf (11, 20, 34, 46 or 55 Nm) – all within the same frame size. It features a self-contained oil supply and is based on the popular 1100 series governor. The actuator is designed for use with the Viking range of digital electronic governors and engine management systems. A booster unit can be supplied for applications where minimal start air consumption is required. The actuator includes an electric start fuel limit option and can be used with other manufacturers' electronic governors. Base plate adaptors are available to convert the actuator to other manufacturers' base designs.
