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:24 valve V-6 vs. 12 valve V-6?
The 24 valve has 2 intake and 2 exhaust valves when the 12 valve only has 1 intake and exhaust per cylinder, the 24 would give u more power but will most likely use more gas.
Q:What's an easy way to remember aortic, pulmonary, mitral tricuspid valves leaflets orientations?
The tricuspid valve has three leaflets which are thin and membranous with commissures that appear more like indentations than true commissures. The TV apparatus is similar to the mitral valve but has greater variability and thinner leaflets. The three leaflets are the anterior, septal and posterior leaflets, with the anterior and septal being larger than the posterior leaflet. TV= tricuspid valve tri-cuspid=3(three leaflets) leaflets=3leaflets Tricuspid: Having three flaps or cusps. The valve that is called the tricuspid valve is situated between the right atrium and right ventricle and permits blood to flow only from the atrium into the ventricle. The aortic valve in the heart also has three cusps. Tricuspid valve (Anat.), the valve, consisting of three triangular membranous flaps, at the opening of the right auricle into the right ventricle in the heart of most mammals; -- sometimes called the tricuspid valves, each flap being regarded as a valve. Take care as always
Q:i'm being charged $300 to replace a 75gallon water heater valve, is that too much?
What, just the valve? What valve? A stop valve in the supply or delivery line? Or the temperature and pressure valve? There's no way on God's green earth I'd ever fork over $300 for this job. I can do it myself in thirty minutes. The TP valve would take less than ten minutes. Granted I'm a handyman and I have a shopful of tools and 20 years experience. But back in the day, when I'd never done any maintenance work, I replaced my own water heater from start to finish and it only took a couple of hours. Unless there's something major going on that you're not disclosing to us, it sounds like a pretty serious overcharge. [edit] To answer your additional questions, I wouldn't pay that much to replace all three valves. The valves themselves aren't very expensive, and the only really difficult part of this entire operation is getting all the water under control to replace the drain valve. Something's going to get wet, and that tends to make homeowners annoyed and difficult customers. The TP valve is a simple wrench-in, wrench-out replacement. Water off, power off, drain below the level of the valve and out it comes. Control valve requires turning off the house's water, but less draining. Replacing the drain valve requires draining the entire heater but again it's a wrench-in, wrench-out job. Easy.
Q:1993 pontiac bonneville bad egr valve question ?
A catalytic converter will glows red hot when raw fuel is introduced directly into it. The dealer is incorrect in saying that there is a problem with the converter itself. The problem is stemming from either the fuel or ignition system which would allow unburned fuel to pass through to the converter. Some possibilities are improper ignition timing, fouled spark plugs, air pump failure, Even though the catalytic converter glowing red hot is not caused from a clog if the converter is operated too long at a high temperature, its substrate will melt and re-harden. This would in turn cause exhaust blockage. Fix the fuel problem first and if the engine is still running rough (without a red hot converter), then it will need to be replaced.
Q:Does valve oil and/or slide grease expire?
As the others have pointed out, no, it doesn't expire, but I never use old grease myself. You get lots of spit transfer from whatever you're lubing up to the grease/oil and the bacteria from said spit has just been.. sitting there. Growing. And possibly multiplying. Sorry. I'm a germaphobe. That's just yucky to me.

Q:1995 Intrepid keeps burning EGR Valves?
are you sure its the egr valves going bad or not the egr solenoids causing you to get the code,that will make it appear that an egr has gone bad when it really hasn't,good luck.
Q:Cylinder heads and Exhaust valves?
The only reason to change out a cylinder head is because the exhaust valves have been burnt or the valves in general have been used to a point they don't seat any longer. Which means the engine compression to fire the cylinders on compression stokes is too low to be efficient to operate. Or the cylinder head has a crack in it and leaks water or the compressed gasses from the engine compression blow into the water jacket through the cracks causing the coolant to blow out and the engine to overheat.
Q:Water shut off valve?
you should have a shut off where the waterline enters the buliding and 1 at the water meter
Q:What prevents the valves in the heart from being pushed backwards?
the heart valves maintain the unidirectional flow of blood in the heart by opening and closing depending on the difference in pressure on each side. (wiki) So I would assume that the pressure of blood flow is what prevents the valve from pushing backwards. ALSO Atrioventricular valves These are small valves that prevent backflow from the ventricles into the atrium during systole. They are anchored to the wall of the ventricle by chordae tendineae, which prevent the valve from inverting. The chordae tendineae are attached to papillary muscles that cause tension to better hold the valve. Together, the papillary muscles and the chordae tendineae are known as the subvalvular apparatus. The function of the subvalvular apparatus is to keep the valves from prolapsing into the atria when they close. The subvalvular apparatus have no effect on the opening and closure of the valves, however. This is caused entirely by the pressure gradient across the valve.
