Q:electronic valves from the '60s uses?
It depends what they are, specifically. Valves used in TVs or RF receivers are not worth much. Audio and RF transmitter tubes might be worth something.
Q:sprinkler valve leaking water?
I have been given the equivalent line from our water application whilst the stress valve broke and blew up our water softener it rather is the 1st element on the line from their tension regulator. luckily, it has a life-time insurance yet their plumber instructed me that it extremely was once the accountability city on the grounds that of the stress regulator which they admitted to being at fault whilst they replaced it.
Q:Craftsman mower valves?
i can explain it a bit more personally just email me if you want me to i will be happy to help with this sort of problem!
Q:Cardiac valves?
The two atrioventricular (AV) valves ensure blood flows from the atria to the ventricles, and not the other way. These are large, multicusped valves that prevent backflow from the ventricles into the atria during systole. They are anchored to the wall of the ventricle by chordae tendinae, that prevent the valve from inverting. The two semilunar (SL) valves are present in the arteries leaving the heart, and they prevent blood flowing back from the arteries into the ventricles. These are positioned on the pulmonary artery and the aorta. These valves do not have chordae tendinae, but are more similar to valves in veins.
Q:Who knows anything about a leaking heart valve?
If the medical doctors say might, then he ought to get his valve mounted in might. think of approximately it. you could stay with purely area of your liver, purely one kidney, and you will possibly be able to stay devoid of your gall bladder. yet you could not stay devoid of your coronary heart, all muscle groups and chambers and valves! it particularly is not a sturdy time for him? What ought to probable be greater significant than getting his coronary heart mounted?
Q:Is valve oil and rotary oil the same?
Yes and no. Most pro repair shops use a heavier oil on the bearings and your valve oil on the inside of the valve. Confused? On both ends of the valve are the real friction points, the bearings. One can be seen under the valve cap. Take the cap off and push the valve, the little post you see moving in the middle is the bearing. The other one is on the underside. It comes out of the valve body and has the string post screwed on it. The only point to oil the bottom bearing is that little crack you see where it comes out of the valve body. You put a drop of sewing machine oil on those 2 bearing spots, 3 in 1 oil also works. Then pull a valve slide and put a few drops of valve oil down into the valve. That is how it is done. BTW, there is no difference between valve oil and rotor oil most of the time.
Q:where is the location of the iac valve, 97 galant?
The idle air control valve can be found under the throttle body. In order to get to it: 1. Disconnect negative battery cable. 2. Remove air intake from throttle body. 3. Disconnect throttle body cable. 4. Disconnect sensor connectors from IAC valve, and throttle position sensor. 5. Remove 4 bolts from throttle body using 10mm socket wrench. 6. Take throttle body, turn bottom side up, remove 4 mounting screws from IAC Once you do that you have removed the IAC. Reverse the steps to put it back on starting at number 6 and working your way back to number one How do you replace an air idle control valve? Replacing an idle control valve can be a daunting task. For your specific application, we recommend to ask in our car forum for advice. Here we will describe the basic process for replacing your idle control valve. Please note that for different cars and trucks the process will not be the same. Steps to replace your idle control valve You will want to begin by first gaining access to the idle control valve. In order to do this you will need to remove the air filter assembly, along with the air mass sensor and the air mass meter boot. Once you remove this whole assembly, you should have easy access to the throttle body. Remove the four bolts that secure the throttle body to the intake manifold. Usually on the bottom of the throttle body, on fuel injected cars, there is a idle control valve. To remove the old valve, simply unscrew or unbolt it. Bolt on the new valve, and reinstall everything. Make sure you replace your throttle body gasket at this time.
Q:how dose the presta valve work?
Q:Tips for building/connecting a sprinkler valve manifold (see details)?
valve manifolds are something that requires practice and experience. i used to struggle with them at work until i did a good bit of them. 3 zones is not that many valves so it shouldnt be too difficult. if they wont line up exactly right, i would recommend adding longer peices of pipe to the mainline side of the vavles and re routing the supply line futher back and you will have more room to flex the pipe and vavles into the Tees and 90s. do not use any form of flexible pipe on any mainline. you will regret it. lol the bigger the hole you dig will give you the most room and the more pipe, and room will give you more flexability to build the manifold. it is easier to connect the valves the way you did it first though, but you can do it either way. good luck and hope this helps
Q:86 flhtc flowed heads bigger cylinders 86 cubic 10-1 pistons keep bending valves what can i do to stop bending?
I'm leaning toward the valve float or lifters pumping up idea. I wouldn't double up the head gaskets because you're asking for a leak, especially with your high compression. A good way to determine how much actual clearance you have between the piston and valve is to stick some soft modeling clay on top of the piston where the valves are, torque down the head, turn the engine over and take it apart. You will then be able to measure how thin the clay was flattened out to, giving you an idea of the clearance. If you seem to have plenty of clearance, then it may be valve float. If you've swapped out the cam, also compare the timing as well as the lift. The actual lift may not be a problem, but if it's opening sooner or later than stock, that may be when the valve and piston collide.
