Q:Solenoid Valve Control?

Q:how to adjust valve lash on a gmc yukon?
remove valve covers, watch front left two lifters and turn engine, by bolt that holds harmonic dampener to front of crankshaft, so mark on dampener lines up with mark on front cover. If rocker arms do not move as marks line up engine should be on top dead center number 1 cylinder. Now you can adjust exhaust valves 1, 3, 4, 8 and intake valves 1, 2, 5, 7 [ odd numbers are on the left bank from the front 1,3,5,7 even on the right bank from the front 2,4,6,8]. Adjust by turning nut in rocker arm out until movement is felt than tighten until all movement is gone and tighten one turn more. After done with the first eight valves turn engine over one full turn till marks line up again. Then adjust exhaust valves 2,5,6,7 and intake valves 3,4,6,8 the same way.
Q:Valve replacement surgery?
Hi David, just saw your post. I was young when I had my valve replaced. I was 37, now am 42. My mother had her valve replaced at the age of 54. Honestly, that is the oldest person I know of that has had valve replacement. As with any surgery, there are alot of risks young or old. The older a person is though it may be tougher especially if he has a lot of other health problems. Just take all of this into consideration when you and your father are discussing all the details, etc. and find out any and all options that he has before proceeding with surgery. Best wishes to you both.
Q:Bent Valve!!!!!!!?
if a compression attempt is widespread then you certainly have not got a tendency valve to bend it it has to hit some thing like the piston and that's no longer exceptionally. have you ever run low on oil or crushed on her a splash? if it consistently knocks decrease than the comparable condition its probably piston appropriate. if it knocks each and every each and every now and then then its gasoline or ignition appropriate
Q:what is the difference between a pressure control valve, a temp control valve, and a flow control valve?
In principle all valves are flow control valves. What changes is the variable they are controlling. A temperature control valve controls a flow to heat or cool another fluid. A pressure control valve, controls a flow to maintain the pressure in a vessel. As pointed earlier, valves can be self contained, i.e., the sensor is part of the control mechanism, usually a diaprhagm which moves the valve stem. and a spring to adjust a set point. Or, they can be pneumatic or electronic, in which case there is an external power source, transducer and controller to adjust set point, gain, reset and rate. This gives additional flexibility, if needed, depending on the process to be controlled. .
Q:Another EGR valve question?
Bring it to the dealer, they will take it apart and find out whether it's just clogged or broken or something else - like for example, DPFE sensor on Fords
Q:valve core?
You can do it yourself very cheaply. All you need to do is go to Walmart or a Auto parts store and get four valve cores and a valve core remover, then go to a gas station the has a air compressor. Remove the valve cores and put the new ones in, you don't have to let all the air out Just put the new valve core in and air the tire back up. I would check the old valve cores before I changed them or have them changed by mixing water and soap together and put in on the top of the valve core, if it bubbles then you need to replace them, if it doesn't bubble someone is just try to scam you.
Q:Is it possible to extract a valve stem from an old tire or do you have to buy them individually to have just?
you cant get used one out and re-use it they tear up when you remove them unless their the ones with the nuts on them that bolt in,pull in types cant be re-used ,any parts store sells those in a pack of 4 or most tire shops will give you one if you ask them for it,good luck
Q:What is anti-surge valves testing?
An anti-surge valve is a valve that automatically opens to produce a flow through a centrifugal compressor to prevent surging of the compressor at a low flow rate. At surge conditions, there is no forward flow in the compressor and the compressor shaft will move foreword and backwards against the thrust bearing. This is damaging to the compressor and causes a terrible noise, that once you hear a surging compressor, you will never forget it. On an air compressor, the surge control valve will discharge to the air through a muffler. For process gas, it will discharge to another part of the process. The answer to your question depends on whether the data relates to the flow through the anti-surge valve of the compressor. It could even be a record of how fast the surge control valve operates. Based on this, no one can give you an answer for certain. TexMav
Q:Sound when I open or close rain bird sprinkler valve?
It could be the solenoid. It could be actuating very slowly and hammering when it tries to shut off. The solenoids are only $5 or $6. Not a significant expense. I just had to replace an entire valve. Not costly but a good size hole while I was working on it.
