Q: my dad's friend died, and dad had been keeping some valves of his. now we've been left with about 400 valves and i'm going to sell them.my main question is what are they used for? i need to write a description for ebay but have no idea what they're for! anyone know?also, how much should i sell them for? on the box it says 11 shillings, which i worked out as ?1.32, but how much should i sell them for on ebay? there's prices on ebay that are about 50p to ?1.50 for most of them, but some are about ?7 but have no bids at all. how much should i start the bidding at?also, if you could give me any other information that i should put in the description, i would really appretiate it :)they are mainly 'Mullard' valves (the company name) but some are 'MAZDA'thanks! :D: It depends what they are, specifically. Valves used in TVs or RF receivers are not worth much. Audio and RF transmitter tubes might be worth something.

Q: hello my names matt and i have a 1997 eclipse 2.0 non turbo with 94k miles and the semi circul seal on my valve cover gasket has a small leak that i see oil dripping and i dont think the pcv valve has ever bin replaced could any of those cause my exhaust to burn oil maby a bad fuel injector? theres no oil in the top of the engine on the spark plugs when i check them all, the piston rings and the headgasket r not worn or cracked so idk what it could be some one please help: Valve cover gasket no PCV yes.

Q: i have a 05 kx250f, new valves recently,will pop start, idle runs high, has compresion, new kckstarter gear but it wont kickstart. someone said the valves need to be shimmed.anybody have any ideals? thanks.: Who okorder /

Q: List words that rhyme with valve...I need these.: Sorry to all those saying salve and halve (and one could add calve) -- in these words the L is silent! Thus for valve there is no PERFECT rhyme (defined as using exactly the same sounds from the vowel of the accented syllable to the end of the word). The best you can do is a NEAR rhyme in which most of the sounds match, with as few sounds changed as possible, and the 'substitutes' matching as closely as possible. These COULD include dropping the L altogether, but I'm not so sure that salve, etc. work very well Varying the vowel: delve, elve [from a scientific acronym], helve (handle of a tool such as an ax), shelve, swelve ('to swallow'), twelve revolve, solve Varying the final consonant (and possibly the vowel) The closest match would be changing /v/ to /f/, but these words, again, mostly have a silent L (half, calf, ). The only exception? The name Ralph also changing the vowel: elf, shelf (but the -v forms are better matches) a voiced /th/ (as in this NOT thin) is fairly close to the /v/ sound -- as a result mouth (the verb form) might work. (why does mouth work better than salve? Perhaps because the ow sound is closer to the al of valve than to the short-a of salve, cat, etc.) health and wealth --with a changed vowel and un-voiced /th/ is little tougher, but maybe. . .

Q: Com wires attached to com and all individual valve wires are attached. The valves work manually( turn on by hand), I open the valve to allow the box to take over and the sprinklers run. Is this just residual water in the lines??: I would test the leads inside the control box first... You will have to run the controls manually to troubleshoot the problem. Get a voltage meter to test for the 24 volts at the transformer connections inside the box... If you do not have the 24 volts then the problem will be the transformer. If you have the correct voltage from the transformer then you can test each of the station terminals to common. Test through each station to see if you have 24 volts at each station terminal, but you may have to remove the wires off to test. If you do not have power coming from each station… then the problem will be the rain bird control. The next step would be testing the wires… If you reconnect the wires… test just prior at each valve location to see if you have the 24 volts between the common and each station wire… if you can prove out that there is 24 volts at this location then you’re down to the final testing. Reconnect the valves – one side to the common and the other to each station wire… Getting the power (24v) to the valve should have cleared your problem. Good Luck… Running the valves manually will not affect the operation of the rainbird control... but with my rainbird valves.. you can shut off the valves completely and disable the electrical controls of the valve... make sure that you have not closed the valve off manually preventing the electrical side... a problem with rainbird controls. This does not have anything to do with residual water in the lines... I would test this side first before you get into the electrical side... could save you a lot of time.

Q: I need to know how to use a valve spring compressor, the type that looks like a c-clamp. I understand the fork side goes on top of the spring and the circular side goes on the valve to push and hold. There are also two little scoop things in the middle of the fork that i don't know what they are used for. If i can get a step by step instruction, you will get the best answer: the scoop thing goes on the retainer or (the part that holds the spring in place) first there should be an adjustment on top of the tool where the fork is...put the compressor on the retainer..and adjust the screws until it fits tight on the retainer....then will have to adjust the bottom of the compressor where the handle is so that when you close the handle it pushes down the spring far enough to get the two keepers (two little half moon clips that hold the valve into the retainer....but first before you do anything...u must wear safety glasses if a keeper shoots out of there it may hit u in the face......after you put your glasses on and before you use the compressor take a hammer and hit the top of the retainer that u want to remove...DO NOT HIT THE TOP OF THE VALVE...it will damage the valve and you may end up needing a new one...hitting the retainer loosens the keepers so it will be easy to remove them....when you collapse the handle you can see the keepers in the retainer ..it may be help full to pull them out with a magnet..then slowly release the compassion with the handle and your done....this is hard to do at first and will require some practice to get good at it...be careful u can get hurt using this tool...i have been doing this for 30+ years so i have first hand exp. on both areas good luck

Q: does it moves up and down with the valve stem??: A poppet valve is a valve consisting of a hole, usually round or oval, and a tapered plug, usually a disk shape on the end of a shaft also called a valve stem. The shaft guides the plug portion by sliding through a valve.. not sure if you are talking about tire valve stems? if so the poppet valve moves within the valve stem. I have also heard them referred to as Schrader valves see link

Q: we are researching fluid power (pneumatics and hydraulics) in my high school engineering class. Does anyone know another name for a valve? I've been able to find different types, but I can't come up with any different names for a valve. Anyone have any ideas?: Valve comes from latin valva. There is not other name for it in engineering, but some times is referred as a cock, if the valve is used as shutoff valve, it is also known as shutoff cock. For irrigation, sometimes large gate valves are also known as gates. I can give you many names for the type of valves but I can't think of any other name that replaces valve.

Q: I have a road bike that has schrader valve tubes and my current tire is rated to 90 psi max. I ordered some new tires that are 100 to 120 psi max. Will the schrader valve tube hold that kind of psi? I dont really want to buy converters and new tubes right now.: These valves are used on large trucks which often run there tire pressure at 100 psi and there is no problem. I am a truckdriver and see no reason why they should fail at the pressure you are planning to run at. They are a reliable valve.

Q: I have a WRX. slightly modified. im getting some upgrades here soon. clutch, brakes, and catback exhaust. i have a blow off valve i bought a while back, but found out it was illegal here in cali. if you know about blow off valves, then respond. is it worth putting on? what are the consciences of having one illegally if noticed by cops? all i know is that it sounds bad ***! :): I doubt the cops would notice and if they do find out which is highly unlikely to happen you would just get a fix it ticket. i live in cali and i hear cars with blow off values all the time so my advice is don't trip and put it on your car. it will sound so bad ***!
