Q:fisher control valve
Artspremo okorder )
Q:okay so i recently brought a trumpet and the valve keys were getting stuck. i used the valve oil and it worked. but then when i put the valve key back in and tried blowing through no sound came out. i think it's because i didnt put it back in right. now my question is how do i put it in right? i tried everything but it's still not making a sound. thanks,
The first thing you should check is the order of the valves. take them all out and look on the sides of them for a number. One should have a 1 on it, another will have a 3 and the other one will probably be unmarked but that's obviously the one in the middle. On the outside of your trumpet there will be a 1 and a 3. The valve with the 1 on it goes in the slot that has a 1 on the outside, etc. Make sure you put these in right. if it's still not playing after you put the valves in and they're secured, twist the tops of the valves where the pearls are clockwise until they don't turn anymore. This should fix your problem.
Q:I know what a valve is, but I would like to know what an actuator does?
Valve actuators are part of a motor driven valve, the part that drives it. Generally it is an electric, hydraulic or pneumatic motor. The valve may be on/off, or regulated by a feedback servo system to open or close controlled amounts. The type of valve comes into it too, as some valves are more or less on or off, and others allow fine control without excessive force. Usually the valve and actuator are a package. Valves with actuators are useful for remote control and automatic control of processes. Some valves may need an actuator so they can be operated safely because of the hazards around them. Large valves may need an actuator because they need too much power to operate manually in a reasonable time.
Q:I think the piece leaking is a valve;it is one solid piece of copper with two tubes, one which is a half inch that connectsinto the incoming hot water and then a small outgoing one that connects to the faucet and I don't know how to find a replacement part .. I think it is a Delta but I am not sure ... the house is 10 years old but where can I just find a valve instead of replacing the entire faucet if I don't know what the make or model is ?Any websites with pics of replacement valves for Roman Tubs??
Remove the valve and take it to a plumbing supply store. Home Depot and the like may have what you're looking for; but you're more likely to find it at a plumber's supply. They are the only ones I've ever found who carry odd bits.
Q:I have a '98 Dodge Caravan 3.0 and the valve cover gasket is bad. How do I replace it?
take the bolts off pull off old cover and do the same with new cover!
Q:1991 Buick Spirit smokes early for five minutes in morning, from exhaust. Tried every carburator and gas cleanative fluid. Mechanic says Valve job'.
Probably just the valve stem seals need replacing. NOT a entire 'valve job'. The seals help scrape oil off of valve stem to lower the amount of oil weeping into cylinder when engine is running or turned off. As the rubber ages, it cracks and loses its elasticity and doesn't wipe the stem properly. This is a lot cheaper versus a full 3-angle valve job which requires removal of the heads.. Get a second opinion.
Q:So I know the main purpose of the EGR valve is to recirculate some exhaust to the cylinders to reduce NOx emissions. However, a mechanic told me that a malfunctioning EGR valve can make the engine run way hotter, and that this can damage the pistons, or other components of the engine, over time. Is that true?
Yes, very true. It would help if you stated what vehicle it was for. But let's say it's a Ford F-series truck with the 6.0L diesel, highly known for this problem. You can actually purchase an EGR delete which actually bypasses the valve so it won't burn the piston rings (the actual part that burns up). Buying this item only costs a few hundred and will save you thousands in the long run.
Q:i have a 1991 rm125 and i want to open the power valves myself can anyone tell me how to do thisTHANKS!
dude leave the power valves alone. you do not know what you are doing.
Q:We live in a four story sixteen unity apartment building. There are two radiators in our apartment. The on in the living room is large and we can't turn it on with out water coming out of the little valve on the end, which I am assuming is there to release excess pressure. It doesn't matter if we leave it on for an hour or two days—water still comes out. It has warped the wood below it.How can I stop this? I would really like to have heat on both sides of my apartment.Thanks!
The little valve needs to be changed with a new one,that valve has a small leather inside and it is to spit out water and air until the leather gets wet ,and then stops, then when the leather gets dried out ,it will do the same thing again and again, This is a auto radiator air bleeding type valve used for many years in radiator heating systems................Ok.......Mel........ Hope this helps you...
Q:In aircraft reciprocating engine, if valve spring surge happen?1. Why happen?2. Affect to engine?3. Result?4. Feeling?
Its in a car engine but the fault is near the same. The good news is that in aircraft there are mostly multi-spring valve springs to help prevent the resonance problem that can happen with a single spring. (If one goes resonant, the other one doesn't.) I think what that means is that if you have valve spring surges in an aircraft engine, you probably have a broken spring or weak on the assembly. (just a guess but if they don't go resonant at the same time then how would you get the surge?) The affect, not good. Result - rough at a certain RPM or range of RPM even temp. related Feeling - rough
