Products Description of Swing Check Valve

Check valves are used in pipes under pressures between PN1.6~16.0MPa(Class150~2500Lb), working temperatures-196~600, They are used in industries include oil, chemistry, pharmaceutical, fertilizer, and power gene-ration to prevent the backward flux of the media.

The main structure features of Swing Check Valve:

1The products feature a reasonable structure, reliable seal, good performance and nice modeling.
Either soft or hard seal can be selected for the product upon different working conditions.The sealing face is built up with Co-based 
carbide alloy, leaving a better wearability, corrosion and scrap resistance and a longer duration.
Small opening pressure, the disc can be opened fully with a very small pressure differential.
Inside-set bolt-bearing structure reduces leakage and reliable use.
PN≥16.0Mpa (class1500), the middle cavity uses a self-tightening sealing structure to have the sealing performance reinforced along 
with the pressure rise so as to ensure the sealing performance.
Different parts materials and different sizes for flange, butt-welding are available for sensible combination according to different working facts and customers' requirements.

Q:700r4 throttle valve......?
The only thing i can think you could have done i bent the peice that comes out of the trans. If the throttle valve still returns like a spring when you pull it with your fingers and you can still hook the tv cable to it it should be fine. unhook the tv cable at the carb or throttle body to hook it to the valve then hook it back to the carb or throttle body.
Q:Dangers of mitral valve prolapse?
There are many people with mitral valve prolapse that never have symptoms related to it and never have any problems as a result. Mitral valve prolapse can lead to the backflow of blood through the mitral valve known as mitral regurgitation. This can potentially lead to abnormal heart rhythms, such as atrial fibrillation. The concern with skydiving is that it would lead to a surge of adrenaline resulting in increased heart rate, strength of heart contractions and overall workload of the heart. If you have MVP without regurgitation, then your risk would be similar to the general population. If you have regurgitation it depends on the severity the regurgitation. If you have mild regurgitation, then it also should not be a problem. If you have severe regurgitation, then you could run into problems from the increased workload of the heart. In this case, I would suggest you discuss it with your Cardiologist. It is unlikely that you have atrial fibrillation. If you by chance do, then it depends on how well your heart rate is controlled. If there is any doubt, then ask your Cardiologist. Good luck.

Q:Leaky Valve...?
In reply to the above: I have no clue where Alex M is getting this idiotic information from, but that's just a big load of hogwash...kind of like Dr. Mercola -- who Alex seems to always be toting. Mercola's one of the biggest jokes in medicine today. Now...to your question... If you have a leaking valve (I assume this was diagnosed via an echocardiogram), then it depends on the location and amount of the leak. There are many valves that can leak in the heart. At the age of 53, I would say this sounds more like a mild regurgitation to me. In this case, it poses a relatively LOW risk for anyone, regardless of age or history of disease. If you're currently asymptomatic of it, and don't have a poor ejection fraction (the heart's capacity to eject blood), then I would not worry about it. Sounds like your doctor didn't explain things too well though, so I would call him back for more details or arrange an office visit so you can ask questions and get answers. I don't think a second opinion is necessary, but you are certainly welcome to get one if it will make you feel more informed. I have had MANY patients with this same kind of diagnosis, and they are just fine! No worries. We just do serial echocardiograms on them to evaluate it. Best wishes to you!
Q:What is valve tipping?
valve tapping what is valve tipping search yahoo answers for valve tapping i saw a resolved question about how to fix this problem
Q:What causes burnt valves?
I was told that burned valves resulted from a poor machining job. By the way, I also have a Toyota. Hmmmmm. The car had all the valves replaced and the head gasket as well with only 12,000 miles on it.
Q:steam radiators valves?
First off these are vents , the valves are at the bottom of the radiator where the pipes come in. Sounds like the vents are either closed or broken. Try turning the adjustment screw if that doesn't work I recomend replacing the with vent from a company called ventrite the valve you are looking for is a vent rite #1. These are adjustable vents used to balance the heat throughout your unit the dial at the bottom is labeled 1-8 start with all of them on 8. Now when the radiators heat up if you find some are getting hotter faster turn those down a notch and check again in a day or so.
Q:How do you put trumpet valves in?
see if there is a slight protrusion on the valve. probably on a piece of plastic near or above the spring of the valve? that should fit in a notch in the trumpet valve tube. Just insert your valve partly in until the protrusion is resting on a ledge-like part. Then turn your valve around the tube gently until you hear a click when the notch goes in. You are right, the number on the valve usually faces the side where the mouthpiece is. Make sure your other valves are also placed in there correctly. If all else fails, ask the person who's teaching or taught you to play trumpet. or go to a trumpet store. Enjoy practicing!
Q:fill valve is squirting water?
Find out the source of the squirting water, you may still salvage the valve by just deflecting the water with an ordinary material like a plastic bottle cutaway assuming your level control valve is in perfect condition. Or to be safe just buy a new valve.
Q:How do I set my home radiator valve?
I would think the easiest way would be to put a thermometer on the radiator (with the bulb in the air flow), turn the heat on to one setting and record the temperatures each half hour for about 4 hours. Then, turn the adjustment to a higher (or lower) number and repeat that. That way, you'd know which way to turn to set it. Of course, the level at which you'd be comfortable would be found by trying different settings. Assuming the adustment is a valve, valves in the USA will open by turning counter-clockwise. Closing is, of course, clockwise. Hope that helps. EDIT: I received your email - I don't mind at all! OK, so you have only one valve for all the radiators. Without knowing anything else, I'd say you just removed the part called the bonnet (the upper half of a valve). It shouldn't matter which number it's set on if it's reinstalled correctly. When a valve is removed, the best way to put back is to open it slightly (turn counterclockwise to a low number), then reinstall the bonnet. Once it's back in, it should work like normal. If that doesn't work, perhaps you can get a plumber or a local handyman to check it. As to the upper ones being airlocked, it really sounds like there is a blockage in the supply line. I am assuming this is steam-heat radiator that is supplied by a boiler-type heating unit?
