Q: I've been playing french horn in school for about five years, and I'm not exceptional by any means! But I love the instrument. Our school district bought a french horn a few years ago when we didn't have enough french horns for players. The almost new Holton has great tone. But unfortunately it fell into ignorant hands and has been neglected for two years. I just received the instrument and cleaned it up and got it back up to snuff, except for the valves. I can't get them to run smoothly!! They act all gummed up. I've put oil in the top and bottom of the valve, and I've dropped a couple drops in the tubes down onto the valves, but they're still gummed up! Do I need to use more oil?? Or what? Any suggestions?: Sounds like your oiling correctly but you need to get the dried oil out, that's the gum your feeling. One way is to have the school send it to the repair shop, its not your horn so don't spend any money on it. Another way is to flush them out with a thin valve oil. Where can you buy a quart of valve oil? Walmart and Kmart has it but not labeled as valve oil. Look for Lantern oil , the stuff used in oil lamps, it is very cheap and many of the valve oils are made of the same stuff. Take out all the crooks on the instrument and flood the valve with the lamp oil, this should flush out the gum. After you have dumped the lamp oil re-oil the way you have been. (Lamp oil is not dangerous, it burns if you hold a match to it but that is about it, you can also use charcoal lighter)

Q: We have an oil steam system. There are Dole valves - 1A on each of the radiators. We bought new ones. They don't seem to be working. They look like a bullet shape with a screw in (on the side of the bullet) to the radiator. On the top of the bullet is a slit with numbers 1-10 on a dial. A picture we saw on the web showed a plastic piece of tubing in the screw part which looks like it goes into the radiator. If we remove the valve, the radiator gets hot with steam coming out of the hole. With the new valve on, the radiator barely gets warm. We're in Piscataway, NJ 08854. H-E-L-P.: Seems to me that a steam valve would need to hold a lot more pressure than a hot water valve. Steam is a high pressure gas and water is a liquid irregardless how hot it is (below boiling point) I am not a qualified plumber or boiler tech but personally I wouldn't use a steam valve for water or vise versa.

Q: I had the EGR valve and solenoid replaced and I'm not sure they needed to be replaced.: they are cheap replace it

Q: I have 1998 Husqvarna WR250 2-stroke and the torque valve isnt connected and i am wondering if its worth it4 me to track down the part that ismissing to get it working. does the torque valve increase power much? please help cos im wondering whether i should sell bike and get motocross bike instead.: The torque valve (it's called the power valve, by most manufacturers) changes the exhaust port timing, depending on the RPMs of the engine. The valve blocks part of the top of the exhaust port. As the engine RPMs increase, the valve lifts up. The distance between the top of the exhaust port's opening and the top of the cylinder is changed. When the piston is moving down on it's power stroke, the opening of the exhaust port is exposed sooner (due to the valve lifting up) and the ignited fuel exits the cylinder faster. This process of changing the exhaust port's timing, creates more explosive power for the engine. So of course if it was hooked up, the engine's performance would increase.

Q: Also, Is a pneumatic control valve an ATC or an ATO; is it a FO or FC valve?: When the individual ego is very high, directly relating itself to universal oneness is a difficult process, so he or she can get married and experience and grow with each other and than expand further. Such elaborate procedures are followed in ancient tantra philosophies. There there is no husband and wife tagging required, just two partners agree upon to help each others evolve and help each other as a subject in there experiment and practices. My brother coyote above makes this point very clear. -- Deito Harirnama Harirnama Harirnama Kevalam.

Q: When looking at the head on my chevy 350 how do I determine which is the intake valve and which is the exhaust valve?: Intake valve will line up with the intake port from the intake manifold and the exhaust valve will line up with the exhaust port going to the exhaust manifold or header....intake is usually larger of the two.

Q: pls. tell me the differnce between isolation and block valves and also where it to be used .: An okorder /. There's numerous systems that use isolation valves. Let's say you want to make some ice cream, you open the isolation valve to let the milk flow into the mixer, then open the valve to let in the cream. Depending on the valve type, you could then open it to allow in the vanilla, sugar, egg, etc. All with the same valve. It just keeps the ingredients from coming in contact . A block valve is used to shut off a supply, so you can perform maintenance, or just stop the flow.

Q: We have a main gas valve outside and there's a gas valve by out air condition and we want to know which way if off and on .. Does anybody know !!!: i just went outside checked mine it is in the straight up position. the handle that you turn off or on is straight up with the hole for the padlock facing straight up also. hope this helps happy holidays to you yours.

Q: My brother is 32 years old.He has an enlarged heart ,a murmur,high blood pressure and heart regurgitation.He may be having the valve replacement surgery.I was wondering if anyone has had these things wrong with them and had the valve surgery and did well afterwards.Any information would be very much appreciated.: Guy I work with just had 2 valves replaced. He honestly didn't know anything was a matter until he collapsed at work. They ran some tests and figured out that was his problem. Talked to him a few days after his surgery and he said he hasn't felt this good in a long time. Its a common procedure nowadays, and your brother should most definitely be in good hands. Keep us informed, and best of luck to you both!
