It's a rather subjective question, but I imagine the most common answer would be "the valve" or "the transistor."
Pentair Mini Max does not have a pilot light, it has a Electronic ignition. If your having trouble getting it to fire up you could have a problem with a plugged burner, bad ignition or a bad valve.
A transistor acts like a valve or gate that opens and closes, and allows a current to flow. Since the amount of current that flows is controlled by another input, they can be used to make amplifiers. Carbon microphones and vacuum tubes have the same property, and so have also been used to make amplifiers historically.
electronic shifter solenoid-pwmA P.W.M modulator valve is an electronic shifter controlled by an electronic pulse to shift your cars transmission, normally refered to as an electronic shifter solenoid.
we know that in a transistor we have three types of regions: EMITTER, COLLECTOR, BASE, and we know that emitter is highly doped, so charge carriers are very high, so resistance is very less, and on the other side collector is moderately doped so charge carriers are less, so resistance is very high. So from the above concept we conclude that in a transistor current is flowing from low resistance to high resistance. for example the 100 electrons are moving from emitter to base, in base only some (4 electrons) of the electrons are neutralized, and remaining 96 electrons are moved to collector terminal through high resistance path. so now same current flowing through high resistance so voltage amplified.
Thermionic valve
where can i get a pilot valve for gas air compressor
magic
The PCV valve on my 2005 Pilot is bolted horizontally into the side of the valve cover right next to where the oil dipstick is.
Gas not turned on to water heater. Gas valve on water heater not set to pilot setting. Faulty gas valve. Igniter for lighting pilot not working.
No, it has an electronically controlled valve body,there is no modulator valve.
we would still have valve tv and radios the size of a briefcase.... computers as we know them would not exist but they would exist filling a building the size of an office block doing the work a credit card sized calculator can do now. the original LEO (lyons electronic office) a valve computer, did payroll and simple (say a small modern shop) stock control for a few dozen companies in central london in the 1950/60s.. it had hundreds of workers and was the size of a modern hypermarket... the computing power was similar to the original sinclair zx80. transistors were an accident... they were trying to make a "solid state valve" and got the bipolar transistor by accident (transistors are current controlled whilst valves are voltage controlled).... the closest we have got to the solid state valve is the multi-vertical fet used in microprocessors. GE invented the transistor and saw no point in it... it was "bought" by "mr sony" who made the first transistor radio.... the rest is history GE could not see the point of making "radiograms" smaller than big bits of furniture

No. The pilot valve is closed when no flame is sensed by the thermocouple.
have you checked to see that gas is getting to the valve if it is the pilot could be stopped up pull it try to clean it soak in spray carb cleaner ect. blow out with compressed air or replace with new oneAnswerTake the tubing loose from the pilot assembly and depress the pilot valve on the gas valve to see if gas is getting to the assembly. If it is, you have a clogged pilot orifice; take a thin piece of wire and clean it out. If you have no gas getting to the orifice, you still have a bad gas valve or your gas is not turned on.
Your transmission is most likely a 4T60E. If so, it has no modulator valve. This transmission is electronically controlled from the ECM. Line pressure, which is what the old modulator valve controlled, is now controlled by an internal pcm solenoid.
so when the pilot goes out the gas valve is shut off
