Manual Operated Lug Butterfly Valve

Q: What would this envole, can i size up/down the port on the existing valve with just changing the mechanical componts.: On okorder /

Q: Ok, I recent rebuilt a set of vortec heads, but the valves I got are a bit longer than stock, I believe .1 competition products pn I2552P. I also installed howards cam 98214 springs with 10° locks and retainers, the locks are +.035. I was just wondering if I would have enough spring pressure.: I would be worried more about your geometry right now than spring pressure. Your saying the valves are .1 longer? Thats quite a bit.

Q: My question mainly pertains to Electric Motor-driven Motor Operated Valve Actuators.: a MOV consist of electrical motor, actuator and valve. the motor is driven by electric and its shaft is coupled to valve; therefore rotating motor shaft develop forward or backward movement of the valve thru gear mechanism. The actuator is controlling the ON or OFF, rotate to LEFT or RIGHT of the electrical motor; the actuator can be set base on process control (i.e level, flow, pressure etc). when rotating of the motor is controlled, so it does the valve opening.

Q: When my son was three I switched Dr's for him. The new doctor said has he always had a heart murmur I said no that's the first I've heard of it so we went for test. Anyway heart specialist did all tests said my son had Bav a valve disorder in the heart. He said it is very common. However everyone I've ever talked to has never heard of it. My question is does anyone have this what is your story and have you had to have your valve replaced. My son is very healthy active I'm just worried. Any help would be greatly appreciated....thank you!!: it is a common cause of murmurs in children, and ordinarily they grow out of it, you can relax.

Q: I have been diagnosed with a bicuspid aortic valve and a discrete stenosis under the valve at 11 years old. I am now 25. My cardiologist told me I might need a valve replacement a 70. Can people actually live long with that condition? I don't understand it. And he only wants me to have an ultrasound every 3 years because nothing has changed in the past 10 years. Can my condition change in a short time? At a dangerous level? I have bad anxiety because of this.: The mitral valve between the left atrium and left ventricle only has two cusps and it works fine. Since the valve going into the left ventricle has two valves, it stands to reason that a similar valve going out of the left ventricle would function similarly if it was the same size and shape. The number of cusps is not entirely related to how well the valve functions. In your case, the opening of the aortic valve is slightly smaller than normal, but clearly capable of passing an adequate amount of blood. The stenosis alone may be the only problem caused by the valve. The stenosis you have likely creates some back pressure when the left ventricle contracts. The heart compensates partly for the back pressure but this prolonged compensation wears on the heart valve a little more than normal. So, you end up with a heart that more or less functions normally but the back pressure and compensation cause the heart valve to wear out faster than normal. Its a gradual effect. The type of damage done from this circumstance is not something that changes rapidly. Evaluating the condition every three years is still probably a very cautious approach and its not certain that the stenosis will ever become a significant problem even if you live well beyond 70 years.

Q: 1. Why is there an exaust valve. Isnt it only a port. Where do the gases that go into the exaust valve go?2. How does air enter the intake valve. If you look at a push rod diagram, you cant see where the air is enteringCan someone explain to me the valve concept: The camshaft is turned by the crank shaft and is in time with it. the cam shaft either pushes the valves open and closed or pushes on lifters or pushrods that drive the rocker assemblies that move the valves. On a two cycle engine yes under most circumstances the exhaust valve is only a port. On a 4 cycle engine like on a vehicle it has exhaust and intake valves. When the piston is on the exhaust stroke the exhaust valve is pushed open, the piston comes up and pushes the exhaust gas out through the open valve, near the top of the piston stroke the intake valve begins to open as well and for a very brief moment both valves are open this is known as valve overlap. This allows incoming air to help expel the burnt exhaust gas. The exhaust gas goes out through the exhaust port through the exhaust piping and into the air. When an engine is running or cranking (pistons moving) it creates a natural vacuum which draws in air, when the intake valves open air is drawn into the combustion chamber pretty simple. Then the air is mixed with fuel vapor and when the piston comes up on the compression stroke the spark plug fires and the air fuel mix burns and drives the piston down. The valves allow the engine (AKA some call it an air pump) to work and pump air. Without them the pistons would do nothing absolutely nothing.

Q: Beneath my kitchen sink are two shut off valves for the water; one for hot, one for cold. The hot water valve has never successfully stopped all water flow, so we've always resorted to shutting off the main line. Well, now that's not working. We shut off the main water line to the house, all water everywhere is non-functioning except for the hot water pipe beneath my sink. It's now causing the faucet to constantly stream water, so it's something we have to resolve ASAP. I'd like to avoid calling a plumber, but my knowledge in such areas is very limited. Can anyone give me any decent suggestions? For the record, I did take apart the faucet fixture just in case, thoroughly cleaned it, and replaced all of the washers I had access to; but we only just bought the faucet in September, so I can't see a worn washer as being the problem. I also tried to tighten the nut behind the handle on the valve. It didn't effect the dripping.: This Site Might Help You. RE: Leaking water valve under my kitchen sink?

Q: My car (RWD) has vacuum leak and has the code PO171/PO174. I find some engine oil at the bolt well of the valve cover on the bank 2 side. Can the vacuum leak come from the valve cover? What is the main function of the valve cover? Thanks.: there is no vacuum in the valve cover. the vacuum is in the intake the valve cover is leaking oil. the valve cover covers the rocker arms.

Q: i got a filler neck for my dodge dakota and was wondering how to put it on. can anyone send me a link or help me. and also what does my EGR valve look like and i cant seem to find a new one not even at the dealer. i was told to clean it how do i do this. can someone send me a link or pic what it look like. thanks: The VECI decal map under your hodd will show you EXACTLY where your EGR valve is. You may need a magnifying glass. The valve can be removed and cleaned with Gum-out or foaming cleaner (amsoil). When you are done, re-install the valve. While you are getting ambitious, clean your throttle body and plate, and the IDLE AIR CONTROL VALVE. A dirty IAC is the most prominant reason for the EGR valve to clog up. Running Gum-out through your intake system will clean out your O2 sensors, as well. Good luck!!

Q: how to replace a valve cover gasket on a 98 pontiac sunfire 2.2. engine?: First off, you remove the PCV hose and unscrew the plastic nut that retains the PCV valve. Next you remove the air intake tube from the throttle body and the air intake housing. Now locate the bracket on the side of the throttle body that contains the throttle cable. Remove the 2 bolts from this bracket and remove the cables from the throttle body. You should now be able to remove the valve cover from any obstructions. If you are not cleaning the valve cover, there is no need to remove the PCV valve. If you are cleaning it with soap and water, take the PCV out. The gasket is one piece and rubber, but you may find it a pain to keep the gasket in the groove on the valve cover, so you might try some yellow weatherstrip sealer to help hold the gasket in place. Let it dry for a little while before reinstalling the valve cover, so the gasket doesn't 'roll' out of the groove on the corners, or it will leak heavily. Good luck.
