How do you adjust the throttle valve cable?
Tip: Consult the owner’s manual for any specifications for your car’s make and model. Adjust the cable by a small increment then have your helper press the gas pedal all the way down and check the cable at WOT. Lengthening the cable will allow the vehicle to shift earlier and the shift will be softer.
What makes a throttling valve a fluid control device?
THROTTLING VALVES Valves that are utilized as fluid control devices are typically “throttling valves”. Such valves experience internal velocity and internal pressure gradients (both positive and negative) that conclude with a permanent pressure loss (∆P) from the inlet pipe-to-outlet pipe connections.
How is the dip of a throttling valve determined?
-5- The depth of the vena contracta “dip” is primarily a function of a throttling valve’s geometry; globe vs. butterfly, etc. The important parameter in determining the PVCis – “FL– Liquid Pressure Recovery Factor”.
When does throttling valve trim change its velocity?
Throttling valve trim (plug-seat) experiences relatively high internal velocities nearly 100% of operating time. In comparison, ON-OFF automated or manual valves experi- ence velocity changes ONLY when being actuated from “open-to-closed”, or vice versa; i.e. a few seconds or minutes.

What do you need to know about a throttle position sensor?
What Is a Throttle Position Sensor? This vital sensor allows your engine to maintain a proper amount of air. This feature is dependent on the throttle valve. When you press down on the gas pedal, your throttle body unit’s valve opens.
What happens when the throttle valve cable is out of specification?
When the throttle valve cable is out of specification, the transmission can shift early, shift late or not shift at all. Before the throttle valve cable can be adjusted, the transmission must be in good working order. First, you will need to find out if the transmission is faulty or if the transmission just needs to be adjusted.
Can a throttle control valve be used for speed control?
Throttle control, it is often referred to as a speed control valve, in fact, it is sometimes used only to regulate the flow and is not used for speed regulation.
