1. Manual Wafer Butterfly Valve Description：
A butterfly valve is a valve which can be used for isolating or regulating flow. The closing mechanism takes the form of a disk. Operation is similar to that of a ball valve, which allows for quick shut off. Butterfly valves are generally favored because they are lower in cost to other valve designs as well as being lighter in weight, meaning less support is required.

2.Main Features of the Manual Wafer Butterfly Valve
1. Small in size and light in weight, easy instillation and maintenance. It can be mounted wherever needed
2. Simple and compact construction, quick 90 degrees on-off operation
3. Minimized operating torque, energy saving
4. Flow curve teeing to straight line, excellent regulation performance
5. Long service life, standing the test of tens of thousands opening/closing operations
6. Bubbles-tight sealing with no leakage under the pressure test

1. What is manual wafer butterfly valve?
A: Wafer style is the more common of the two and is less expensive than the lug style. The wafer style butterfly valve is just about the standard. It ís so common that no one even bothers to use the word "wafer" when ordering a butterfly valve. It is taken for granted that if a butterfly valve is ordered, a wafer style will be received.
2. What is the working principle of manual wafer butterfly valve?
A: A butterfly valve is from a family of valves called quarter-turn valves. In operation, the valve is fully open or closed when the disc is rotated a quarter turn. The "butterfly" is a metal disc mounted on a rod. When the valve is closed, the disc is turned so that it completely blocks off the passageway.

Q:where is the bleed valve in a 97 taurus????thank you: remove or loose radiator cap crank motor top off radaitor and over flow jug crank motor with cap off either way crank motor let run air will come out if cap is loose or off and it dont get air trap unless its been apart such as a hose replace or coolant drained type into search box how to fill a radiator how to check a overheating car how to check engine coolant how to replace engine coolant how to bleed air out of radiator

Q:Can someone please help me on this anatomy question:Describe the physical similarities and differences in the structure of the AV valves and the semilunar valves.Thanks: av valves are anchored to the wall of the ventricle by chordae tendinae, multicusped valves while semilunar valves do not have chordae tendinae, but are more similar to valves in veins. positioned on the pulmonary artery and the aorta both have the same function of prevent backflow of blood

Q:My son was born with bicuspid aortic valve which has developed a leak. He is now on enalipril 2x per day to decrease the afterflow and buy some time before he has to have surgery, but the doctor has discussed our options and we basically have to choose when it comes down to it, whether we go with a valve repair, or valve replacement and if we do replacement we can do mechanical or donated valve or The Ross procedure. And he will probably be under 5 yrs old when this needs done, (he's 2 now) so I would like to keep him off of coumadin (blood thinner) so he can play sports in school if he would like. But I also want to do what is the best for him long term. Any advice would be helpful. thanks: OK I HAVE A 4 YEAR OLD THAT HAS AEROTIC STENOSIS WHICH MEANS THAT AT THE AGE OF TEN HE WILL HAVE TO HAVE A VALVE TRANSPLANT. THE OPTIONS RIGHT NOW ARE A PIG VALVE, WHICH LASTS AS LONG AS A PIG WOULD LIVE, OR A SYNTHETIC VALVE WHICH CAN CAUSE CLOTTING. BUT I WATCHED A DOCUTMENTARY ON A HEALTH SHOW ABOUT A MONTH AGO, AND DOCTORS HAVE INVENTED A WAY TO GROW A HEART VALVE USING CELLS FROM YOUR KIDS HEART. NOW IT WONT BE APPROVED FOR ANOTHER 10 YEARS BUT I JUST THOUGHT I WOULD LET YOU KNOW THAT IT HAS ALLREADY BEEN TESTED AND WAS SUCESSFULL, IF I HEAR ANYTHING ELSE I WILL TRY TO FIND YOUR EMAIL AND LET YOU KNOW. IM PLANNING ON DOING THE PIG VALVE UNTILL THE MEDICAL BOARD APPROVES THE REAL VALVES, THAN I WILL HAVE THAT DONE TO MY SON, SO I WILL NEVER HAVE TO WORRY ABOUT IT AGAIN. GOOD LUCK, I KINDA KNOW WHAT YOUR GOING THROUGH. keep in touch with me, and let me know.

Q:hello!I'm designing a floor cleaner and for a water release system i was thinking of using a ball valve, connected to an actuator,however i'm not fully sure what to look for, and although I can buy the actuator and ball valve together, I'm not sure how to connect it to a motor and battery?If anyone can help my with this I'd really appreciate it!!Thank You!!: it is going to be to long of an answere to bypass by, yet you have a often closed valve and a often open valve. So while air is provided, one opens and the different closes. you may artwork something out with that based how your set up is going to be. it rather is the solenoids i'm talking approximately.

Q:Our reactor is cooled by a cooling water system. The line pressure is around 4 bars and the pipe size is 42. How to select a good valve for that service?: You'd also need to know design flow ranges, ultimate flow desired, pressure drop acceptable across valve, and the average temperature of cooling water the valve will see or the range it will see if varies much. You would need to decide if you want to use a ball valve, butterfly valve, of a globe valve to throttle the water.

Q:I was diagnosed with Mitral Valve Prolapse when I was 18. I am 23 now and feel like my symptoms have only gotten worse. Sometimes I could just be still and have severe chest pains with slight paralysis in my arms. It's like my body locks up from the pain. Recently I had an episode and I immediately started crying from 3 seconds of severe chest pain. For the past three days I've had this headache in my temples that sends a slight numbness down my jaw. I didn't know if these symptoms were in any way related to my MVP. I'm going to see the doctor today and plan on mentioning it. Does anyone have these same symptoms or an idea of what is wrong?Thank you!: Although mitral valve prolapse is a lifelong disorder, many people with this condition never have symptoms. When diagnosed, people may be surprised to learn that they have a heart abnormality. When signs and symptoms do occur with mitral valve prolapse, it's typically because blood is leaking backward through the valve (regurgitation). Symptoms can vary widely from one person to another. They tend to be mild, develop gradually and may include: A racing or irregular heartbeat (arrhythmia) Dizziness, lightheadedness Difficulty breathing or shortness of breath, often when lying flat or during physical exertion Fatigue Chest pain that's not associated with a heart attack or coronary artery disease When your heart is working properly, the mitral valve closes during contraction of the left ventricle to prevent blood from flowing back into your heart's upper left chamber (left atrium). But in some people with MVP, the mitral valve malfunctions. In these people, the mitral valve leaflets are abnormal with extra tissue, bulging (prolapsing) like a parachute into their left atrium each time the heart contracts. The bulging may keep the valve from closing tightly. This may not cause problems if only a small amount of blood leaks back into the atrium. When blood leaks backwards through the valve, it's called mitral regurgitation (MR). MR can cause symptoms. Take care always! OIRAM

Q:I have a no start on a briggs and straon 16.5 OHV. It has spark, and fuel. and backfire's through the intake. I took off the top of the motor to check the key way and it was in place. I think its a valve timing issue but what times the valve? I have not removed the flywheel yet because i need a puller. Is there another key way under the flywheel that times the valves: No, there is not another key. Valve timing is controlled by a gear on the camshaft and a gear on the crankshaft. There are marks stamped on the gears that have to be matched when putting the engine together. Without breaking one of the gears, valve timing will not change. I would guess that you have something wrong with the intake valve or valve seat. Take the valve cover off and see if the valve is moving, and check the clearance. I believe it should be .003-.005. If the valve is moving freely and the clearance is ok the head will have to come off to check the valve head and the seat. Did you hit something with the mower? Are you certain that the key is intact? With the flywheel nut off you should be able to see both keyways and the key. Make sure that you torque the flywheel nut back on to 60 ft lbs or so or you will shear the key when it starts.

Q:1998 Ford Crown Victoria LX 4.6L Use 89 Octane BP, Shell, Chevron gas. When the engine is under stress(acceleration or going up incline) the engine sounds like the valves are chattering. I can increase the rpm's and the chattering goes away. Had the same problem with 95 Thunderbird 4.6 and have heard other ford cars going down the road with this problem. Air leak? Don't really want to use higher octane due to gas prices and possible engine damage. Also, in the thunderbird, i used a bottle of octane boost and the next day a valve spring broke. Was the octane boost a possible cause?: it is not valve chatter, it is called Pinging, it is a fairly common problem, what it is caused by is hot spots in the engine, or by overly advanced spark timing, i would check your base timing, perhaps even back it off a degree or two, i would also run a bottle of marvel mystery oil, or gm top engine cleaner through a vacuum line to burn out the crud that has built up, the sum total of these repairs: about 15 bucks, the savings: your engine! as for your t-bird, it was the pinging that broke the valve spring, not the tank of hi octane. hope this helps

Q:I'm drawing a complete diagram of the heart, but I'm unsure of the positions of the different valves. I know there are the pulmoary valve, the aortic valve, tricuspid/right AV, bicuspid/left AV, semilunar valves, mitral...but I know there are several names for some of them, like I think the mitral and the bicuspid are the same...but there are so many sources online I don't know which to believe. If anyone knows for absolute sure the right names and where they are it would be very appreciated if you could help :): There are 4 valves on the heart. Right atrium Left ventricle Left atrium Right ventricle. The atriums are the top of the heart...the more smaler ones and the ventricles are th larger ones which are below the atriums.

Q:I have a intake valve leakage in both my car and truck. If there some sort of quick fix i could use to stop the leakage for about 1 month.: IF the valves are correctly adjusted, then the only solution is a valve job. Certain vehicle engines are more prone to burning valves than others.
