FEATURES & FUNCTIONALITY
The PGPL actuator/driver is an electro-hydraulic actuator with a proportional driver interface that can be used with electronic controls providing a 0 to 200 mA position signal. The actuator is designed for use with a Woodward 2301A, 723PLUS, Peak® 150, and 505 or similar electronic controller. It is an easy replacement for PGL and PGD type governors and offers the advantages of electronic control and the convenience of using existing PG-type drive and linkage. 
 
The actuator has its own 2.5 liter (2.6 quart) oil sump and does not need a separate oil supply. It actuator operates with drive speeds from 200 to 1500 rpm. Applications with high drive speed or high ambient temperatures may require a cooler.
 
The PGPL driver converts a given electrical signal into a mA output to the actuator. This then drives the output shaft position through the action of a torque motor and follower-type pilot valve. A contactless sensor located on the power cylinder provides the position feedback necessary for loop closure.  
 
Power cylinders with 16, 23, 39, and 79 J (12, 17, 29, and 58 ft-lb) outputs are available with linear output. Power cylinders with 16, 23, 39, and 79 N-m (12, 17, 29, and 58 lb-ft) outputs are also available with rotary output.
