Q:What is the purpose of those new valves on bikes that are longer and skinnier and that you?
There are schrader valves which are bigger diameter and are used also for automotive tires. They have a spring-loaded center pin that gets pushed down and opened when a inflating head is used. The spring is what keeps the air in the tube. The presta valve is the skinnier one. It does not rely on a spring to keep the valve close. The air pressure inside the tube keeps the valve closed. Generally, less expensive bikes use schraders while better bikes use prestas. All decent pumps have pump heads that accomodate both types. Either it is done by manually reversing the inside of the head assembly to change between presta and schrader or the head automatically adjusts or you use the appropriate one when the head has holes for both.
Q:What is the torque specs for a valve cover?
Valve Cover Torque
Q:moderately leaky heart valve?
You'll probably have more tests done to see if you really have a leaky heart valve. It depends on which valve it is and what the cause is. The most common cause is to have a bicuspid aortic valve (two valve leaflets instead of 3). That can cause long term problems, so that is corrected by surgery to replace your aortic valve. Once that happens, you'll be fine. I'm not sure what you have, though, so there's no way to know for sure what your problem is. In general all leaky valves need to be replaced surgically if they're leaky enough b/c they eventually cause the heart to stop pumping well and lead to heart failure. The most common thing is what I mentioned, though. There's always a chance that your test was incorrect. Good luck to you.
Q:how many valves does a human heart have?
All four valves are not essential. Many patients have Pulmonary regurg after a surgery for Fallot's tetrology. Other three valves are important but valve leaks are better tolerated on the rt side than on the left side. Stenosis of any valve causes obstruction to circulation and so it causes problems.
Q:Cylinder heads and Exhaust valves?
To answer your first question only, the benefits of changing cylinder heads and valves would be to improve the overall performance of the engine, like increasing its horse power, speed and fuel consumption. To prove to the vessels owner that this needs to be done, a compression test should be done on each cylinder by a mechanic. This will show how each cylinder is functioning, and the results need to be cross referenced with the compression specifications for that specific engine.
Q:Any idea on selecting and sizing control valves?
Specialty valves should be sized/recommended by the manufacturer because of the different influences that may be encountered by the valve. Example: Temperature ranges, chemical composition of coolant, type of valve(ball, gate, tempering, other) all will have some effect. I would say take a look at the old one if it exists and if you're not satisfied with its performance, then cross reference it with other companies like Amtrol, Wilkins, etc. This would be the safest most logical method.
Q:Plumbing question - Fill Valve?
If you had proper plumbing this would not happen. Have a look at an Armitage Shanks catalogue..............oh sorry, you are in the US arent you....... o well
Q:Whats a better Blow off valve for a pt cruiser?
The Mopar Performance blow off valve is really going to be your best bet if the two are roughly the same price. The reason I say that is because the Mopar unit is designed to fit onto that car, therefore it is engineered to release excess pressure at a safe level for that engine. The Greddy unit is also going to typically require modification to make it fit and function properly. Unfortunately, what they don't tell you about universal units is the reason they are universal is because they don't fit anything until you make them to fit, you just have enough material and hardware to get creative with it. If you are looking to extensively modify your engine, then it may benefit you to go with the universal unit and just wait until you have your piping cut exactly the way you want it, this may give you better location or clearance using the aftermarket unit, but otherwise like I said, I would go with the factory performance BOV. If you have any further questions about your cruiser, please feel free to email me, I have had a cruiser for a couple of years now and have also done lots of customizing to cruisers for friends.
Q:Will schrader valve tubes work at 110 psi?
Yes they will hold.
Q:Is valve standard of API and ISO same?
This Site Might Help You. RE: Is valve standard of API and ISO same? what's the differences of American standard valve standard and Europe valve standard. Like API598 and ISO5208 , EN12266 valve inspection standard, or API600 valve design manufacture standard,and EN598,
