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:bent exhaust valve?
that would be caused by high rpm with no load, had it happen in my car years ago, well before i acquired it. vacuum modulator line cam off, car was driven home for about 15 miles at normal speeds (OUCH, 45 in first gear in a 68 gto) bent 4 rods and some other damage that i do not remember.
Q:Nos tank with scuba valve??
srry but if u do that it works very poorly so i would buy that scuba tank
Q:where are angle valves used ?
I okorder.com/... I hope that I adequately answered your question. Wingman
Q:How important are Tire Valve Stem Caps in retaining tire air pressure?
Tire valve caps are the final seal again potential failure in the valve of the valve stem. A good tire valve cap will come with high quality rubber seal that push against the circumferential 'ring' of the valve stem and thereby help to contain the air should the valve fail or not containing the air very well. You observation of your tire (the one with the missing cap) losing air confirms that this could be a possibility. Of course, the other possibility is that your tire is having a slow leak - go to any petrol station, and it could be rectified at a minimal cost. Note: Even if the valve is perfectly good, if the tire go over a bump or pot hole, it is still susceptible to lost of air due to the additional pressure asserted during the hit.
Q:Are valves connected to tbe whole rocker arm assembly?
I am guessing you mean will the valves come out if you remove the rocker assy. The answer to that question is no. The valves are retained by little half-moon clips that are wedged in a slot in the valve stems. The force of the valve springs against the top valve washer keeps them in place while also preventing the washer from sliding up past the top of the stem. You can remove the rocker assy without having the valves drop into the cylinders. You will have to adjust the gap between the cam lobes and the rockers when reinstalling so it isn't like you can just bolt it back on.
Q:control valve selection?
Q:Is Mitral Valve Prolapse considered heart disease ?
Its a valve disease. It is a valve between the right atria and right ventricle within the heart muscle. Mitral valve prolapse simply is the fact that the valve does not completly close once the blood is pushed down from the atria where the deoxygenated blood is where the new oxygenated blood will be after it goes through the pulminart artery to collect oxygen from the lungs, then comes back to the ventricle. What then happens because of the prolapse is it has a little regurgitation, or spitting back up some fresh oxygenated blood back to the atria, and then continues to the left atria through the corniary vein. Hope that explains why its more of a valve disease than the heart disease. Heart disease has to deal with the heart muscle. And its chambers. Then you have corniary artery disease which focuses on the arteries and veins of the heart and of course the valves which includes your aorta, bicuspid (mitral valve), and your tricuspid.
Q:what is the pupose of valves in the industry/?
the valves control the flow
Q:Help With My EGR Valve?
Flag is right. You should of got the code from AutoZone and posted it here. A trouble code can have several meanings and the salesperson just gave you his best interpretation with his limited knowledge. You either had a P0420, P1410, P1411, P1661 or P1662 code. More than likely it's EGR Valve Position sensor or EGR Vacuum Solenoid depending on the code. It also can be the wires or connectors that plug into them or one of the vacuum hoses to them. About a $40-$70 fix if you do it yourself. You can pull the EGR valve off to inspect it but you need to replace the $1 gasket under it when you are done. On old poorly maintained engines they can clog up with carbon deposits or the vacuum diaphragm can rupture. You can apply vacuum to the valve manually and see if it opens while you have it off. If you have good lungs you can do it with a piece of hose. :) If it works then it's not getting vacuum and most likely it's the EGR Vacuum Solenoid that opens and supplies vacuum to it. The EGR Valve Position Sensor tells the Vacuum Solenoid to open via the ECM. See if you can't get the code and post it.
