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:General Help with replacing shut off valve under kitchen sink- Pics included?
Copper pipes are usually soldered. You might want to call a plumber for this.
Q:how to replace relief valve on hot water tank?
Turn red dial to pilot.Shut the cold water feed off. There is a drain located at the very bottom of the tank youll need to hook a hose or hold a bucket and drain some water out of that. It doesnt need to be much a few buckets or a couple mins of hose will be fine. Then simply un-screw the old one. Put teflon tape and pipe dope if you have it around the new one and tighten in securely. open hot water at your sinks and turn cold water to tank back on slowly and let the sinks run until all air bleeds out and then shut them off. Re- light pilot. Done.
Q:Anyone know anything about mitral valve prolapse?
I have mitral valve prolapse and have lived with it for quite a while. I take no medications for it all. It's more common in females than males, and is usually not a cause of major concern. If your symptoms are worse than before you were diagnosed than you should consult your MD . Some people with mitral valve prolapse require surgery but that is rather uncommon. As with any heart issues there are degrees of involvement. Ask your MD to order an Echo-Cardiogram. It is a non-invasive test, painless and simple. That with whatever other test your MD may suggest should determine how bad the prolapse is. See a (Cardiologist ) is my recommendation. The symptoms that you are having are quite common with this condition, all except the sniffles.
Q:i have a 96 mitsubishi galant and when you press the accelerator it rattles in the valve cover?
Maybe you simply need to re-adjust your valves? Or buy a Lancer.
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:i want to know the detailed reason for pressure drops in expansion valve?
I would wager that those losses, or pressure drops, are due to entrance and exit losses through the valve. Calculate the losses yourself. The mechanism is simply friction and geometry. Perhaps the losses are not what some agency says they are. Physical tests can be used should such phenomena govern costly criteria and baselines.
Q:Does anyone know where the erg valve on a 2001 isuzu rodeo is located?
i'm no longer attentive to that style. some cam sensors are on the front of the engine. some are under the valve conceal. My advice could be, to call the save that offered you the sensor and ask them or call a dealership. in many cases they are satisfied to help. grasp tech 40 yrs.
Q:How much does it generally cost to replace valve seals?
budget $300-400 probably to fix the stem seals. if you have ANY thoughts of replacing the heads with a performance set now is the time...
