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:pcv valves?
PCV stands for positive crankcase ventilator all engines need this device to work properly
Q:i can't pump my presta valve...?
no longer understanding the make of motor vehicle i won't be able to be particular. A valve cover is a straightforward bolt on area. maximum engines won't require an outstanding form of different areas to be bumped off yet that may no longer consistently the case. purely get rid of the bolts/screws protecting the valve cover on and carry it off.
Q:stop intake valve leakage in auto?
what is leaking in to where? assuming that your talking about the intake and exhaust valves,then here goes. if the car and truck are old enough to have a carb on them then if you have gas leaking past the valves then you will need to clean the intake valves, if it's oil leaking into the cylinder then you will need to change out the valve seals-those are located under the valve springs. to do that job you will need an air compressor.if it's compression blowing past the exhaust valves then you will need to pull the heads and have them serviced, same with intake cleaning. sorry no quick fix. either fixed or malfunctioning,those are the choices
Q:Inhaling smoke from valve oil?
Valve oil is basically just mineral oil and various other ingredients. You can buy pure oil, and it's also the main ingredient in baby oil and other medicines. Nothing wrong with burning it.
Q:Which is the intake and which is the exhaust valve?
the intake valve is usually bigger and on the left. the exhaust valve is usually smaller and on the right. at least it is true in small engines (lawnmowers).
Q:Valve/pipe leaking from toilet?
It's called a shut off valve, costs 6-7 dollars depending where you buy it. You will have to match the size of the valve to the size and type of the pipe coming out of the wall, could be copper or threaded steel pipe. Also replace the line from the valve to the toilet, this will have to be matched to the valve as well. Not a hard job but matching up all these things can be tricky if you don't know what you are looking at. Might be easier to get a handyman or plumber. If you do try it yourself do not forget to turn off the water - might have to turn the whole house off.
Q:Automatic hydraulic cylinder reverse flow valve?
Electrically operated hydraulic changeover valve would be simplest. Then all you need is switches to operate first 1 solenoid, then the other, reversing flow. These could be as simple as microswitches operating latching relays to control the valve. An accumulator should be fitted to reduce hydraulic shock from a sudden direction change.
Q:replace pcv valve on 2002 ford explorer?
The PCV Valve is not connected to your brake booster. If it were, engine oil and other debris would be pulled into the booster diaphragm and contaminate it and destroy it. Your PCV Valve is located on one of your Valve Covers. The Valve Covers are the long metal lids that run the full length of your engine on either side. Normally your oil cap is also located on one of the covers so you can fill your engine with oil when needed. The part that you are looking for is normally made of plastic or metal, and it is seated in a rubber grommet in one of the valve covers. You will normally find a single rubber hose coming from it leading to either your air cleaner or a port on the intake plumbing. Normally located before the throttle body. The PCV Valve itself, is a cylindrical object that is normally about 1/2 inch to 3/4 inch round and about an inch to 1.5 inches tall with a single, (sometimes double) port at the top. There is an object on your intake manifold, and sometimes also located below your throttle body, that does look like a PVC Valve. But its not. Its a simple vacuum port connector for access to manifold vacuum to operate things like your brake booster, and some of the emission control devices. I hope that helps you out. Good Luck!
Q:Mitral valve regurgitation?
This means the valves in the heart have a little leakage, so rather than produce complete forward flow there is some reverse flow (regurgitated). To determine how much of a problem this presents to you, find out what your ejection fraction is measured as, anything over 50% is good. Ask your doctor to explain, and put this into prospective for you.
