The model SX and SCX linear actuators and Linkage Kits are designed for direct mounting on the engine to control the throttle lever or to mount in place of the fuel shutoff solenoid for controlling the throttle of spark ignition and diesel engines.

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.

When linked to an engine throttle lever, the actuator and controller maintain engine speed adjusting the fuel requested to obtain preset engine speed settings. This eliminates the droop inherit to mechanical governors.
