FAQ of Cast Steel Check Valve:

Q1:I can’t find the type of steel check valve which I need. what can I do?

The chart above only lists out some common composition of steel check valve parts.We may provide other different parts material composition according to the customer's request or the actual valve working condition.

Q2:Which certification do your products pass?

  Our products are in accordance with ISO 9001ISO 14001API 6AAPI 6DTS CEAPI607/6FA/BS6755.


Q:can a person survive with only one heart valve functioning?
The four valves in the heart are: * The two atrioventricular (AV) valves, which are between the atria and the ventricles, are the mitral valve and the tricuspid valve. * The two semilunar (SL) valves, which are in the arteries leaving the heart, are the aortic valve and the pulmonary valve. Possible Complications:- * Arrhythmias (abnormal heart rhythms), including atrial fibrillation and lethal arrhythmias * Clots to other areas * Endocarditis (infection of the heart valve) * Heart failure * Pulmonary emboli (blood clots in the lungs) * Stroke
Q:The valve on my mountain bike tire has a leak, so I want to go buy a new valve (and maybe a couple spares)... how much is the average cost?Thanks!
Just buy a new tube, I don't even think you can/want to replace the valve on a bike tube. $5 maybe.
Q:I own a 1982 Pontiac Firebird base model which has recently started leaking oil from its Proportioning Valve. I have looked all over the internet for a replacement, and it turns out GM has discontinued the part. Now im faced with difficult and risky task of attempting to fix it, or turn it over to a repair shop as a last resort. The valve seems to leak out of a small circle with a hole the size of a needle inside which was covered by a rubber gasket. I have no clue what this does, and how to repair it.
First up is that the valve is not leaking oil, it is leaking brake fluid. That is bad. The proportioning valve controls the brake pressure to the rear brakes. Most of the braking is done with the front brakes and without the valve you could lock up the rear brakes on medium to hard stops and the rear end could loose traction, that would be a bad thing on a sharp turn. With that said please replace the valve I have never seen a repair kit for them. Have you looked at to GM for the part? They may also have knowledge on a conversion of the master cylinder with the valve built in.
Q:Need some info. Ok, four valves per cylinder is better than two valves per cylinder. Fine, why did Ford REVERT to only 3 valves (my guess is to save cost SOHC)? Audi and VW are using five valves per cylinder on some cars, does this offer any advantage over a four valve engine? Maserati even experimented with a six valve per cylinder!!!! (see link) http://www.maserati-alfieri .uk/alfier... but abandoned it (my guess is cost again?) Why are we stuck at four valves or would more valves actually render more horsepower? Pop some ideas best answer to reasonable answer...
Think of an engine as an air pump - obviously, we want the least amount of restriction for the incoming air and also the least amount for exhausting the compressed air. The ideal situation would be to remove the head during the intake stroke and put it back on during the compression stroke, but, obviously, this isn't possible. On a naturally aspirated engine, the intake is the most critical because the air is moved only by a relatively small difference in pressures. The exhaust stroke, on the other hand, is aided greatly by the super heated temperature and rapid expansion of the gasses. Two intake and one exhaust valve seems to be the most practical and efficient solution - adding more vales means smaller valves and an increase in the overall complexity. I seriously doubt that Maserati ever abandoned ANY automotive idea due to cost restraints. It's far more likely that adding more valves than three or four simply resulted in diminishing returns. Sometimes the allure of a new buzz phrase is nothing more than a marketing ploy - a 16 valve, DOHC, four cylinder engine, for example, is a pretty impressive resume for an engine, regardless of whether it actually is the optimum performance set up or not.
Q:does a 1975 chevy pickup 2wd has a proportioning valve? If so how does it work and the signs it is bad? my truck has disc/drums brakes?
Yes The valve causes your rear brakes too apply before the front brakes .Safety reasons,(If your fronts apply first chances are the rear of the vehicle could come around on you) It utilizes spring pressure and offset valving. There is a rubber button that you must depress to bleed the rear brakes It's an override.
Q:How would this affect the functioning of the heart valves?How would this be detected in a routine examination?
If the heart valves are damaged, they may leak, causing regurgitation of blood. For example, if the mitral valve (between the left atrium and left ventricle) leaks, blood will leak back into the left atrium when the ventricle contracts. This reduces the efficiency of the heart contraction. Regurgitation is easily detected by echocardiography. On routine physical exam it may be detected *if* there is enough leakage/ flow abnormality to cause an audible sound, or murmur, that your physician can hear with his/her stethoscope.
Q:For those of you that have had a heart valve replaced, why did your heart valve go bad?
It depends on the type of the vavle. They usually get worn after 10-15 years.
Q:I have rented a house and the irrigation timer only has wires of one zone.It goes to a single valve then out to a big round cover with 6 zone pipes coming out of it. What the heck kind of set up is this?does it do a mechanical rotation inside that cover? the zones only come on one at a time but every time I turn it on I get a different zone as they are all Zone 1 on the timer.
The single valve is the master control valve. It shuts the system down at the end of the irrigation cycle. It's a safety element in case one of the zone valves doesn't close or close completely. The other valves are probably digitally addressable. Your timer opens the master control valve and then digitally selects each zone valve in turn and waters according to a programmed cycle. These systems are called irrigation sequencers. Some of them are wireless.
Q:One of my valves leaks a small amount of water through the valve and into the water line. why would it leak and what do i have to do to fix it. the valve is a rain jet valve. i would like to fix it without having to remove it from the valve box. inside the valve box there are 8 valves and they are glued in and i dont want to have to remove all of the valves and box.
Sounds okorder ), and so sometimes its almost easier to replace the whole thing. The rain jet valves definitely aren't the best quality either, so if I were you I'd get a better one just to make sure it is going to work for a long time.
Q:Would a 96 saturn egr valve work on a 96 camaro
what approximately it? are you particular you would be able to desire to repalce the valve itself. they are in a place to be run via a sensor and vacuum traces or if old sufficient as yours would desire to be basically vacuum traces. be sure your vacuum traces are stable, without holes....
