Manual Operated Lug Butterfly Valve

Q: I have a Jupiter double horn. The thumb valve will randomly stick down and not want to come back up. It however only does this when I play a scale or am in the middle of a song, so when I ask the director or an instrument repair person to help, they think I'm crazy and see nothing wrong with it. Also, the first valve is slightly bent sideways towards the second valve. I got it used and it came like this. It is not horrible, but that makes it significantly slower than the other valves and sticks a LOT. All repair shops do is take my money and claim they've fixed it when they have done nothing. It is so frustrating. What should I do? And the oil doesn't help with either of these things, which is even MORE frustrating.: Open up the #4 valve cap and flood the top with valve oil, put the cap back on and turn the instrument over. Put valve oil in the crack where the valve comes out of the bottom of the valve case. This can be hard to see. Put some drops on every moving part of the valve action. I can remember the layout of that valve but I don't think you can shoot oil into the valve. Try all that I said above and see if that helps. Rotate and wiggle the valve between each step.

Q: It is burning oil, so that means oil is getting into the combustion chambers....but im not exactly sure which piece has gone bad? or for that matter what the valve guides are in the first place. Could the lifters have gone bad too? Can someone tell me what piece is most likely the cause for the oil leak into the chambers and then a price of how much it would cost to have it fixed. When i start the car it blows a puff and then settles down and then when im at a stop light and push the accelerator it blows a puff and then more or less settles down...sometimes it keeps going for a while. My mechanic put an additive in the oil called stop the smoke or something, and i know that that causes the seals to expand...and it has helped. So. I need someone to give me an overall diagnosis and price range. My mechanic is reluctant to have me do the work, im guessing cause its expensive...but i would rather pay 1000 dollars then buy a new car.: yes we would love to help, except you gave us zero information, in order to even begin to guess whats going on, you need to explain a whole bunch of information if you want any help, like what year make model of car, engine mileage on engine, and any other things that have been done to a coar that you know of. If you have a chevy 350 it was pretty normal to get a puff of smoke out if it when it was cold, this was from worn valve stem seals, and sometimes the design of the seal was a problem, like the umbrella seal for late 80s early 90s, even new some got a few drips of oil and blow a puff of smoke, you say its smoking out the tail pipe, ok when only when cold? or all the time , or under acceleration? when, that is the first clue we need to know ok?

Q: I was told on Tuesday that i have mitral valve prolapse and that i inherited it and that i will be fine. Well i take toporol xl 50 mg because the mitral valve prolapse makes my heart beat fast. For the past week i have noticed that my chest/lungs get tight, kind of like i have congestion in my chest, it comes and goes and sometimes its really bad and sometimes i can tolerate it. Is this normal for someone with the mitral valve condition. My cardiologist didn't go into details about the symptoms and i'm wondering if i should go see another doctor. I do have a sniffly nose and was wondering if this could be symptoms of a cold or something else. Any one out their with my condition having the same problems??? If so what is it???: Haven't had it done before but: It's a pretty involved procedure. Patient is put under general anesthesia and is usually on the cardiopulmonary bypass machine (heart-lung machine) since you can't really replace a heart valve if the heart is beating. mortality for full valve replacement according to wiki is 6-8 percent, prob less than 5% for young healthy patients. Recently, many people have been doing the procedure laparoscopically. Patients are put into the surgical ICU for typically 1-2 days after the surgery. You can be discharged about a week after. Obviously there's risks, this is a very involved and definitely not a simple procedure. However, the cardiothoracic surgeons do these procedures every day for their entire lives-they're very skilled and qualified. good luck!

Q: my valves got dirty long story how do you clean them: Remove the valves, wash them and the horn in warm (NOT hot) water with liquid dish soap. Dry with a clean towel, then oil and reassemble.

Q: My fiance needs his aortic valve replaced. He is 40 yrs old otherwise healthy. I am wondering how long he will be in surgery, how long he be in the hospital and any other info about having this surgery.: where is it performed?

Q: Pressure relief valve on boiler is dripping.Starts to drip more when the boiler is turned on.Bad relief valve?: Yes you have a bad relief valve. The reason it drips more when the boiler is on is due to the amount of pressure and flow of water. These units typically dont rust depending upon the material of the housing. But they do fail there are o-rings internally on these relief valves. I would assume that you have an o-ring that is failing.

Q: I have a 79 ford F-150 and i was wondering where the pcv valve was my truck will start but it wont idle until its reached normal operating temp i was told that it might be my pcv valve is that correct or what else could it be. thanks: Could also be your choke is not working properly. Your pcv valve will not cause an idle problem . But if you need to find it , it`s attached to a hose that is on one of the rocker covers. Hey Mana ! WTF is that crap? Mule

Q: will a blow off valve work with out an intercooler???(civic 2000)and also, is a blow off valve a turbo?whats the diffrence between a turbo and a blow off valve?? thankss..: A blow off or pop off valve controls the boost or pressure the turbo or supercharger is pushing into the engine.A turbo makes the boost.The blow off valve controls it so you wont run too much boost or pressure into your engine and leave pieces of it all over the street.The blow off valve can be adjusted to control the boost,6- 8 lbs.should be sufficient for a street application.The blow off valve simply allows the excess pressure built up in the turbo to be vented or blown off so it wont be forced into the engine.The boost on a supercharged or blower application is controlled by swapping the blower pulley to either underdrive the blower or overdrive the blower,depending on which way you want to go.

Q: hi guys..What is different between globe valve and stop check globe? Is that stop check globe=SDNR JIS std?: I am not even sure what you are talking about. a globe valve is a type of valve that can stop the flow by turn a handel on top of the valve. A check valve on let the flow go one way and stops the flow the other way. hope this help Globe valve From Wikipedia, the free encyclopedia Jump to: navigation, search A Globe valve is a device (specifically a type of valve) for regulating flow in a pipeline, consisting of a movable disk-type element and a stationary ring seat in a generally spherical body.[1] Globe Valves are named for their spherical body shape with the two halves of the body being separated by an internal baffle. This has an opening that forms a seat onto which a movable plug[2] can be screwed in to close (or shut) the valve. The plug is also called a disc or disk.[3][4][5] In globe valves, the plug is connected to a stem which is operated by screw action in manual valves. Typically, automated valves use sliding stems. Automated globe valves have a smooth stem rather than threaded and are opened and closed by an actuator assembly. When a globe valve is manually operated, the stem is turned by a handwheel. Although globe valves in the past had the spherical bodies which gave them their name, many modern globe valves do not have much of a spherical shape. However, the term globe valve is still often used for valves that have such an internal mechanism. In plumbing, valves with such a mechanism are also often called stop valves since they don't have the global appearance, but the term stop valve may refer to valves which are used to stop flow even when they have other mechanisms or designs. Globe valves are used for applications requiring throttling and frequent operation. For example, globe valves or valves with a similar mechanism may be used as sampling valves, which are normally shut except when liquid samples are being taken. Since the baffle restricts flow, they're not recommended where full, unobstructed flow is required.

Q: My husband just found out that one of the heart valves is 100% blocked and the other 3 are 90% or more blocked . He is 78 years old he Is nearly non mobile. What kind of treatment would you suggest?: A heart valve can't be 100% blocked. The heart simply couldn't function. On the other hand, coronary arteries can be blocked as you described. Normally, 4 vessel disease is treated with bypass surgery. In a high risk patient, angioplasty might be an option. However, if he is not having cardiac symptoms , or if he is thought to be TOO high risk, the option is medical treatment. Sit down for a talk with his cardiologist.
