Q: My AC leaks and mechanic says it is shrader valve. Is it expensive?: No okorder /

Q: Can you please explain to me what an atrial valve is and what it does??: By atrial valve, I assume it meant the atrioventricular valves. Basically, in the heart, the blood flows from right atrium, right ventricle, left atrium, left ventricle. The atrioventricular valves are the tricuspid and bicuspid valves. They make sure the blood flows from the right atrium - right ventricle and left atrium - left ventricle respectively and prevents blood from flowing the wrong way in those chambers.

Q: I have a Burnt Valve in my Ford 302 EFI Crown Victoria. I know that i will have to have machine work done to the head but im not even gonna mess around im going to just pull both my heads off since theres alot to remove to even get to the heads i Just need a list of parts that i'm gonna have to buy for this project: take the heads to your local automotive machine shop and have them do the valve job they will fix whats wrong with your heads.and for parts you will need a head set gasket kit from auto zone or summit racing,and new spark plugs wire's oil, antifreeze,belts water pump since you have the room to get to it now,

Q: I need a ball valve that when you shut it off it sends a signal to a light that indicates that it is off.: Never okorder /

Q: Is there a product that can fit over a foot valve to give it further protection in muddy water? I am looking for something for forest firefighting in mind. Something like a screen box something else that can give it further protection. It would be nice if it was small, and compact. Pictures would definitely be an asset. Thanks to everyone that answers. Greatly appreciated.: most foot valves i have bought come with a strainer attached perhaps you should look for that type. if your valve has a strainer you may consider making a further coarse strainer out of a ball of chicken wire and place this over the foot valve assembly(thats what i do for the cold water supply to my house) don't compress the chicken wire very small as it will block up i tie the wire filter on with galvanized wire then i can easily replace it if necessary ps i tried stainless steel pot scourers but they were to fine and blocked easily

Q: sprinkler valve leaking: Most valves are either 3/4 or 1 with female connections. Use the same size male adaptors with teflon tape wraped around the threads and screw it into the valves. Take a photo before you start to refer to when rewiring.

Q: I have a 98 Mitsubishi Mirage, seems there is a valve cover oil leak, i know this can be easily fixed by replacing the gasket.. but how will i know if the leak isn't from the valve cover gasket . Is the cylinder head gasket a major issue also .. if its not really the valve cover thats producing the oil leak should i not worry and just replace the valve cover gasket .?: Valve cover leaks are typically characterized by what you're experiencing: oil oozing out from the cover/cylinder head mating surfaces. If this were your cylinder head gasket, then you'd be experiencing some problems with how the engine runs ...very unlikely it would cause oil to leak from the valve cover. *Do not* simply wrench down on the bolts holding the valve cover; all you will do is crush the gasket and create a bigger leak. Two things you need to do: replace the valve cover gasket and make sure your PVC or crankcase vent system is not blocked. Swapping the gasket is pretty obvious ...they get old and dry out and leak. Checking/cleaning the crankcase vent system keeps compression blow-by gases (a normal thing in engines) from pressurizing the crankcase and forcing oil to seep out in places it shouldn't. A healthy, properly working crankcase vent system helps prevent this.

Q: Hi, I'd like to control a three way solenoid valve like this one:understanding is that an electric current through the solenoid will cause the valve to let air one way while no electric current will have the air flow the other. Is there a piece of equipment like a control box (that can communicate w/ a computer) that would allow me to control the solenoid valve like this? and if so, where would i be able to find something like this....i've googled but no success. I eventually want to control the valve from a computer. Thanks: There are dozens of valves on that link, you have to be more specific. Most valves switch between open/close with application / removal of electrical power. Restricting air flow to one direction is done via a check valve, not something that requires power. Air flow will be from the direction of higher pressure to lower pressure. A valve can stop that flow, it cannot reverse it. You can control the valve with a relay, and that with relay driver IC such as a ULN2003, and that driven by a computer. Depending on the power levels, you may be able to drive the relay directly from the relay driver. .

Q: ex: 4 stroke 16 valve engine: ? r u going to include the number of cylinders?

Q: Defects in which valves would produce the following?1) SEVERE DEPENDENT EDEMA?2) PAROXYSMAL NOCTURNAL DYSPEA3) CONGESTED LIVER?4) DISTENDED JUGULAR VEINS?5) PRODUCTIVE COUGH WITH FROTHY SPUTUMfor 1. i believe it's tricupsid valve, 2. mitra valve please correct me if I'm wrong. Thaanks!: 1. Would require dysfunction on a valve in the right heart generally speaking, so the options would be the likes of tricuspid regurgitation or stenosis, or even pulmonary stenosis. 2. PND is a result of heart failure, particularly regarding the left side of the heart (although of course both sides could be failing). Many valve problems could cause this as an end result... a bit of an odd question, but I'd go with mitral stenosis or regurgitation primarily. 3. Congested liver is the systemic blood system overload (like the oedema), so it is the right heart. Triscuspid regurgitation can cause a congested liver and if you felt this liver, it would be pulsating too. 4. Distended jugular veins are a sign of heart failure. Primarily right heart failure as it is causing blood to be backed up instead of passing through the right heart to the lungs. Tricuspid stenosis or plain old right heart failure (with or without left heart failure at the same time). 5. This is typical of left heart failure as blood backs up into the pulmonary system as the left heart is failing to pump into the systemic circulation. Similar things to PND can cause this. These questions though, are honestly a little on the vague side and half those cases would result from heart failure even without any valvular abnormalities...
