About This Cable style Throttle Control, 36" Overall length for 13HP Engines and Larger. Stroke Length: 1.00 inch. Retracted Spring Force: 28.80 LBF. Throttle Control: For Throttle Control Cable Variation option, please select your Throttle Control Cable HP and OAL (Overall length) from the Variation options above. Throttle Control Cable: 1/8" Male NPT Inlet Connection. The throttle control connects from the unloader to your engine throttle arm and acts as a relay notifying the engine of when its time to run or idle. Each throttle control connects from the throttle outlet on the valve with a Z Bend connection type on the tip of the cable. These Throttle controls are used in conjunction with a pilot valve and an unloader valve. When the compressor reaches the unload (cut-out) pressure the pilot valve sends a pneumatic signal to the throttle control which actuates and extends to reduce the engine speed. As the compressed air is used and the compressor reaches the load (cut-in) pressure the pneumatic signal is discharged by the pilot and the throttle control retracts to return the engine to normal operation speed.
