- 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: So I was diagnosed with a bicuspid aortic valve a couple months ago, I am 20 now and I was told that the defect normal dosent cause problems untill late 30's-40's. I have been having chest pains and at times sever palpitations. Has anyone eles gone through this? Anyone older that has experience with this problem?
- I have a bicuspid aortic valve, it was discovered when I was a few days old. I'm 22 now. If you are having chest pains and palpitations you really need to get in and see a cardiologist. They'll probably give you a heart monitor which is a 24 hour thing that you wear. If you don't catch anything try asking for an even monitor, one that you wear for a month. You really do need to go see someone though. If you want to talk further about it, because I know how scary something like that can be, we can chat further on yahoo or e-mail.
- Q: I have a 2000 jeep grand cherokee v8 4.7L it has a stuck valve making knocking noises my question is can i still drive it !? or is too dangerous
- its only really dangerous to the engine , but possibly you if it quits at a dangerous location this sounds more like something else than a ''stuck'' valve . and personally i would not trust it until you take a further look into the engine and remove a valve cover to see what is causing the problem .
- Q: difference between swing type check valve and non return valve? i need best answer... if swing valve will be opened when the fuel s reverse motion???
- Non-return valve is another name for check valve. A swing check valve is just one type of check valve that uses a hinged gate to allow flow in only one direction. It operates sort of like a one-way fence gate, that you can open by pushing from one side, but you cannot open by pushing on the other side. Other types of check valves: Diaphragm, Ball, Lift, Duckbill. (:-o)
- Q: I was diagnosed with Mitral Valve prolapse...I'm 21, 5.5 tall and 130lbs, I had a healthy lifestyle...my doctor said that my case isn't really sever..but i'm taking medications to keep it this way...something i cannot ask my doctor about, would intercourse be harmful to me? and how should I deal with it??? is it okay for me to have children in the future? and could my MVP be cured without surgery??
- You can lead a normal health life with MVP. What it is is the valve between the left atria and left ventricle doesn't close fully like it is suppost to and some blood seeps back into the atria when the blood is being pushed out of your heart. MVP is more common then you think. The doc even said to you that your case isn't really severe. MVP cannot be cured without surgery at this time. However you'll be fine. Just keep to your doctor visits as scheduled to keep tabs on it.
- Q: okay i have a 1990 plymouth laser. it runs very and the compression is good but it smokes. im thinking valve seals? Also i need to know the tool to remove the seals. Thanx
- The problem could be valve seals if you are getting good compression readings but more than likely is probably a air/fuel mixture problem. Clean and maintenance the intake and fuel system first since its easier and less expensive than the valve seal replacement. The problem could still be worn piston rings since oil getting past the rings would still give good compression readings. Good luck
- Q: Does the new valve get glued or anything or do I just put it on tightly? I cannot tell if the existing valve is glued on or not.
- Is the new valve or the old valve the compression type? If the old valve is then as you take it off you will discover if it is glued (I doubt a compression valve is also glued). Replace the old valve with the same type as the old one. That is always a good rule of thumb to follow. Put it on tightly but DO NOT over-tighten it. 1/4 turn past tight it usually tight enough. I am not a big fan of compression fittings in either copper or cpvc. You may wish to put a glued valve on, if you already have the cleaner, the primer, and the glue, other wise the expense of the materials does not warrant their purchase for the changing of one valve.
- Q: I have a T4-T10 and L5-S1 spinal injury and I recently found out that my tricuspid and my mitral valves leak. I have never had heart problems before I got the spinal injury. Do you think the valve leaks could have been from the trauma when I received the spinal injury?
- Maybe but usually MVP doesnt give people much problems and if it does usually sudden
- Q: what is the purpose of valves such as: gate valve, foot valve and globe valve in the industry?
- Valves are used to stop/start or control the flow of liquids or gases in pipes. There are many many kinds of valves, so if you want info on a specific type, just list that.
- Q: Hey I was wondering how I can test the compression of the valves. Also if they are leaky. I'm thinking about valve rebuilding because my M series conn 8d was bought a few months ago and it was a school instrument. I like how it plays but I feel like there are things that should be done. The valves are one of them. So if there is any test for the valves please let me know. Thanks
- If you like how it plays you might just wish to leave it alone. Anything you do is going to change the way it plays, perhaps to something you don't like. Check compression by pulling the valve slide part way out, wait a second or two and then push the key, as the air fills up the partial vacuum cause by pulling the slide you should hear a nice thunk. If there is no noise when you push the valve the air is leaking around the valve and that's bad compression. Another way to check is just slowly withdraw the valve slide. It should get harder as you pull due to the vacuum, if it comes all the way out it should pop.
