TC63 Pneumatic Throttle Control Valve

The “TC63” pneumatic throttle control valve is used with gas engine-driven compressors to reduce engine speed to idle when the continuous run control (such as Models “LGM20”, “LGM30” & “LGM40” vent unloaders or Model “P25” pilot valve) has reached its “cut-out” setting. This saves fuel and reduces engine and compressor wear.
The “TC63” is connected to the throttle control port of the vent unloader via an air line. The air line can also be connected to a “tee” of the head unloader line for pilot valve installation. The linkage is attached to the throttle lever on the engine.
During 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 to the piston and engine throttle lever to the original, full speed, position.
The “TC63” pneumatic throttle control valve is available in 58” and the operational 516”.
