The model SZ linear actuator is designed for direct mounting on the engine in place of the fuel shutoff solenoid.
This integral type actuator is linkage free and provides precise speed control.The Linear Ball-Bearing design ensures smooth rapid operation of the actuator providing a stable operating speed of the engine when combined with one of PG’s controllers. This combined with low operating currents of less than 1.5 amps result in an actuator with consistent performance over a long operating life.
PG’s linear actuators are designed to respond in milliseconds to changes in the current from a pulse-width modulated signal generated by a PG controller. A magnetic pick-up signal transmitted to the controller provides for closed loop speed control.
The actuator and controller maintain engine speed adjusting the fuel requested to obtain preset engine speed settings. This eliminates the droop inherent to mechanical governors.
