TC12 Standard Throttle Control

The TC12 Throttle Controls are used on gas engine-driven compressors to reduce engine speed to idle when the continuous run control (such as CDI Models LGM20, LGM30, and LGM40 vent unloaders or Model P25 pilot valve) has reached its "cut-out" setting. This saves fuel and reduces engine and compressor wear.

The 1/8" NPT inlet of the TC12 is connected to the throttle control port of the vent unloader or connected into a "tee" of the head unloader line of pilot valve installations. The cable end is attached to the appropriate throttle linkage on the engine and the cable housing is appropriately anchored using the supplied cable clamps.

Materials of construction are brass body and piston with nitrile o-ring and zinc plated steel spring and retaining ring. Vinyl covered, steel armored housing with stainless steel cable. Max temperature 250° F. Minimum pressure 60 PSI, maximum pressure 250 PSI. Used with engines up to 8 HP.

TC12 Large Throttle Control

A larger version of the TC12 Standard Throttle Control, to be used with engines above 8 HP.

TC63 Throttle Control

The TC63 Throttle Controls are used on gas engine-driven compressors to reduce engine speed to idle when the continuous run control (such as CDI Models LGM20, LGM30, and LGM40 vent unloaders or Model P25 pilot valve) has reached its "cut-out" setting. This saves fuel and reduces engine and compressor wear.

The Pneumatic Throttle Control is connected to the throttle control port of the vent unloader via an airline. The airline can also be connected into a "tee" of the head unloader line for pilot valve installations. The linkage is attached to the throttle lever on the engine.

In operation, the vent unloader pilot valve sends a pressure signal to the Pneumatic Throttle Control piston to extend, pushing the throttle lever on the engine to its idle position. At the cut-in setting, the pressure signal that is applied to the Pneumatic Throttle Control is vented by the vent unloader or pilot valve, allowing the spring to return the piston and engine throttle lever to the original full speed position.

The Pneumatic Throttle Control valve is available in 5/8" and the optional 5/16". Please specify the stroke length when ordering. If the stroke is not specified, the 5/8" valve will be shipped.

The materials of construction are as follows: Brass body, washer, piston, jam nuts, steel brackets, music wire linkage and zinc plated screw. The maximum operating temperature is 250° F.
