Q:I have a 2000 jeep grand cherokee v8 4.7L it has a stuck valve making knocking noises my question is can i still drive it !? or is too dangerous: its only really dangerous to the engine , but possibly you if it quits at a dangerous location this sounds more like something else than a ''stuck'' valve . and personally i would not trust it until you take a further look into the engine and remove a valve cover to see what is causing the problem .

Q:ok...i want to find a valve that controls air pressure so i can let it out in 2 different ways for my pneumatic potato gunwhat websites or stores sell this (not home depot): You might have to register on the site to order online. It is free. You can call them and order the catalog. It is free also. Hope this helps Email me if you want me to look it up in my catalog. Don't break any windows. Wingman

Q:I need to make a ball valve that will open with no manual force but by a motor of some sort to spin it and release water. how do i make a ball valve controlled by preferably a motor or other CHEAP device. I need to do this for less that 20$: It's a lot easier and cheaper to buy the valve at a hardware store than make it. You can probably get a motor and gear train from a hobby store. If it doesn't absolutely have to be a ball valve, you can get electric sprinkler valves from just about any home and garden supply. They're specifically designed to control water flow. Just hook it up to a power source and you're good to go. Addition: Just remembered, you can also get battery operated water control valves that connect between a faucet and a hose. I'm pretty sure they're ball valves internally. Prices vary, so shop around. Depending on how fancy you want it to be, they go for about $5.00 and up.

Q:I'm looking for a valve that can be electronically controlled to open and close with a diameter of 1.5'(inches) to 2'(inches) and this valve must be able to withstand 20psi. Any websites or listings of stores I can go to would much appreciated. Thank you: 'ASCO` , (Automatic Switch Company), makes solenoid valves like that.

Q:Hi, in the heart, blood flows through the AV valves and enters the ventricles once the atria have filled up with blood. What opens the AV valves? Fluid pressure from the blood or the SA node pulses?: The opening and closing of the atrioventricular valves is controlled by the differences in pressure across them: When blood passes from an atrium to a ventricle, the atrioventricular valve is pushed open (and the papillary muscles relax and the chordae tendineae lose their tension, becoming slack). At the next stage in the sequence the ventricle contracts. This forces blood out from the ventricle into the artery via which it leaves the heart. This contraction of the ventricle and the corresponding increase in blood pressure within that ventricle also presses the cusps of the atrioventricular valve together until their edges meet, closing the valve. At the same time, the papillary muscles contract and the chordae tendineae tighten - both of which also help to prevent the cusps from enabling the atrioventricular valves to open. When in the next stage of the sequence the ventricle relaxes and the atrium contracts, the blood pressure situation is reversed, the relaxation/tension of the papillary muscles and the chordae tendineae also reverses, and the atrioventricular valve allows blood to pass from the atrium to the ventricle again.

Q:In your explanation, be sure to:- identify the function of a valve in relation to the flow of blood- identify two places in the circulatory system where valves are found - identify one specific valve by name and describe its specific function: This Site Might Help You. RE: Explain the role of valves in the functioning of the circulatory system. I am so confused!? In your explanation, be sure to: - identify the function of a valve in relation to the flow of blood - identify two places in the circulatory system where valves are found - identify one specific valve by name and describe its specific function

Q:I want to find a cheap valve that will let me take a breath in from one place then exhale through a tube going out so that i can attach an airbag to the breathing end and make a little diving lung.: What your looking for is a check valve. Home Depot Be careful, very careful!

Q:I go deer hunting with my dad and he has an artificial heart valve. It isn't too loud, but I can hear it about ten feet away if it's quiet enough. Is it possible that we haven't shot any deer yet because the deer can hear the valve and know to stay away?: I am a deer hunter as well, the deer will more than likely sense your worrying over the thoughts you are having with your dads valve, just relax out there!! Become one with nature, de-stress!! Be grateful to hear the sound of your fathers new valve on life, and be happy he is out there with you!!! These times you will hold with you when he is gone. Make the hunting trips a special time for you and dad. I wish mine were still here to enjoy the hunt with me. Just relax the deer will be there when they are ready. Pray for dad to get the Ultimate buck. Life is short.

Q:How do I adjust valves on a CAT C15 On-highway diesel engine?specifics:435-550 hp 2100 rpm1550-1850 lb-ft 1200 rpm Peak Torqu: Cat C15 6nz

Q:I'm going to replace a valve guide and wondering how I should do it.Should I drill into the existing valve guide to the point it's small enough to pinch with some pliers and pull it out?When I put the new one in, should I use a wooden dowel and an air nailer to pound the guide into place?The more info. the better. It's my first time doing this.Thanks!: Ohhhh man. NO DRILLS. I assume you are referring to an Aluminum Cylinder head. To do it correctly you need a drift punch that has a pilot size of the valve stem, and an outside diameter that is just a few thousands smaller than the guide. Disassemble the head completely, put in Moms oven at the highest setting it will go to ( 5-6 hundred degrees ) Pound old guide out from the combustion camber side. ( have every thing ready to go this FFer will be hot ). Coat new guide with something like STP, put in freezer, carefully align it, then slam it home from the valve train side, don't pussy around, get it in before it attracts the heat of the head, if you stop or it stops you will have to repeat the entire process. If you gall the Aluminum ( say O-**** ) Since you have to hit this thing fairly hard you will need to refinish the inside of the guide with the appropriate reamer. Then refinsh Valve seat ( they never, NEVER line up perfectly )
