Throttle Control Cables

TC12 Throttle Controls are used on gas engine-driven compressors to reduce engine speed to idle when the continuous run control (such as a LGM or Pilot Valve) has reached its cut-out setting. This saves fuel and reduces engine and compressor wear. The 1/8” inlet is connected to the throttle control port of the vent unloader or connected to a “Tee” off the head unloader line for pilot valve installations. The cable is attached to the appropriate throttle linkage on the engine and the cable housing should be anchored using the supplied cable clamps. In operation, the vent unloader or pilot valve sends a pressure signal to the TC12 at the cut-out setting. This causes the TC12 piston to extend the control cable which pushes the throttle lever, causing the engine to idle down. At the cut-in setting, the pressure signal going to the TC12 is vented, allowing the spring to return the piston, cable and throttle lever to the original full speed position. 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. Maximum temperature 250° F. Minimum pressure 60 psi, maximum pressure 250 psi. Available in standard 2 to 7.5 HP and heavy duty 8.5 to 11 HP.
