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.

5.FAQ
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. When the valve is fully open, the disc is rotated a quarter turn so that it allows an almost unrestricted passage of the fluid. The valve may also be opened incrementally to throttle flow.

Q: I've been playing french horn in school for about five years, and I'm not exceptional by any means! But I love the instrument. Our school district bought a french horn a few years ago when we didn't have enough french horns for players. The almost new Holton has great tone. But unfortunately it fell into ignorant hands and has been neglected for two years. I just received the instrument and cleaned it up and got it back up to snuff, except for the valves. I can't get them to run smoothly!! They act all gummed up. I've put oil in the top and bottom of the valve, and I've dropped a couple drops in the tubes down onto the valves, but they're still gummed up! Do I need to use more oil?? Or what? Any suggestions?: Sounds like your oiling correctly but you need to get the dried oil out, that's the gum your feeling. One way is to have the school send it to the repair shop, its not your horn so don't spend any money on it. Another way is to flush them out with a thin valve oil. Where can you buy a quart of valve oil? Walmart and Kmart has it but not labeled as valve oil. Look for Lantern oil , the stuff used in oil lamps, it is very cheap and many of the valve oils are made of the same stuff. Take out all the crooks on the instrument and flood the valve with the lamp oil, this should flush out the gum. After you have dumped the lamp oil re-oil the way you have been. (Lamp oil is not dangerous, it burns if you hold a match to it but that is about it, you can also use charcoal lighter)

Q: I accidentally pushed the pressure release valve on my hot water heater last night. It ran for a while, and did not stop. I turned the water off, the valve on the cold water piper above the water heater, and it stopped running. Will this stop running at some point? The overflow tray fills too quickly for me to drain it. When I turn the water back on it starts pouring out again. HELP!!!: the device once activated rarely reseals It is called a TP valve or temperature and pressure they cost about 15 bucks at the big box stores they usually have a pipe attached to them and are plumbed outside you will need to cut the pipe and unscrew the fitting attache to the TP Now remove and replace the TP make sure to use tape or pipe dope Do not touch the valve in the future reinstall the pipe and solder the pipe back together using a coupler

Q: I know nothing about toliets - so please bare with me. The water valve underneath my toliet is dripping and I have to turn off the water in order for it to stop. It's really annoying to have to turn the water on when I want to flush it and have to empty out the container that is catching all the time. I think it has something to do with the valve itself and I'm PRETTY sure something behind it needs to be tightened - Has this happened to anyone else? What did you do?: You can usually see the water coming out between the packing nut and stem. If it is not the packing nut, sometimes water will trickle down from the connection at the commode and appear to be leaking from the valve. Both leaks will stop when you turn the valve off.

Q: I would like to know about the signal pneumatic valves are drivesn (PWM,PCM?) and about their bandwidth and bit rate. Where can i find info?Thanx!!: first of all, lemme be frank to say that your question is not clear to me. however, i wud like to give my answer below with my understanding of your question. generally, the term pneumatic valve means that the actuating force to operate the valve itself is pneumatic(driven by air pressure) and not the service fluid (i.e. the fluid which passes through the valve). with the above understanding, industrial standard pneumatic pressure could be 3 - 15 psi (or) 0.2 to 1 kg/cm2. on the other hand, if your question means that you want to know about the electrical driven valves, then the industrial standard is 115VAC Solenoid valves (or) 24VDC Solenoid Valves. There could be other ratings as well.

Q: I did a compression test, and I have a broken valve. everything else is in perfect condition besides this valve and I have carbon getting built up in one of my pistons. Can I run the car like this? What cause this from happening what was the cause age?1999 Ford Explorer 4.0 OHV with 146k,miles: Let me guess, cylinder number 3? (passenger rear) Let me explain. In the last year, we've had three 4.0 Explorer's in our shop with a hung valve on #3. The last one we had in the shop, the valve broke without warning and broke the rod which cracked the block on the drivers side. They said it was running fine one second and made some noise and it started missing. It wasn't even knocking when it came in. Something about the #3 on those.

Q: I was getting something to burn and smoke up this empty 2 liter bottle for my friend's brother's science experiment. We didn't find any wood, so I took his trumpet valve oil, dripped some on a piece of wood that wouldn't burn and make it smoke up. Does burning valve oil have any negative side effects as opposed to say, regular oil? I shouldn't have been so lazy and just used vegetable oil or something haha....: Valve oil is basically just mineral oil and various other ingredients. You can buy pure oil, and it's also the main ingredient in baby oil and other medicines. Nothing wrong with burning it.

Q: I saw that they sell a kit to block off the egr valve in my dodge neon. Since this was on a performance site what will this do? Will blocking off the valve give me more horsepower? Should I do it or not? Thanks: i own a repair shop,and it wont give you much more horse power if any,all it does is stop the egr valve from working ,the kit allows you to remove the valve and put a block off plate on it,some say it helps a little i haven't noticed much of a difference in the vehicles that have them on,they just don't recirculate the exhaust gases like they should,which causes any car to fail an emissions test,that's about it,good luck,i hope this help,s.

Q: I pulled the vaccuum line off the valve and nothing happened. I revved the engine and held it a higher rpm and still nothing happened(no vaccuum). Does this mean that the egr valve is bad. I have been having a problem with rough idle, and keeping the car running at a stop sign. I have already changed the pcv valve and that seemed to help a little. Thanks: You have likely got a bit of carbon in the EGR that you can clean after you remove it, I usually spray some penetrating oil into the valve hold my finger over the hole that I sprayed into and turn the valve over, if it leaks the seat is dirty and cleaning the carbon out may help. also push up on the plunger several times to be sure that it doesn't stick alternate carb cleaner with penetrating oil until the valve is free and no longer leaks when inverted. As far as your question the test you described doesn't test the EGR or the EGR solenoid correctly at all. On some the car needs to be in gear to actuate the EGR, all you need to do is check that there is vacuum to the solenoid and that the EGR valve works freely. If the EGR fails to work the check engine light should be on and you can check the code to get a clue as to why.

Q: I am looking for a full valve guitar amp for around ?300.It needs to be loud enough to play with a quietish drum kit.Currently i have looked at an epiphone valve senior in both and combo and cab and head form. i have also looked at some smaller amps such as the vox ac4 but am a bit worried about its small size. any advice would be greatly welcome. many thanks in advance.: Well I have the Valve Jr. and the AC4. The AC4 is a good sounding amp, but even though it is only 1 watt less, the Valve Jr. is much louder. The AC4 is a great practice amp but not enough to jam with a drummer unless he is pretty quiet and you really crank the amp. Never heard one of the new Valve Sr. models but with all of the goodies they added it should sound really good. I had my Jr. modified but it still doesn't have all the cool stuff the Senior has. I think you would really like the Epiphone and at 20 watts you will be more than loud enough. My 5 watt Jr. will get very loud. All I own are low watt class A valve amps, it's the only way to fly!! The Marshall Class 5 might be worth looking at also.

Q: my mechanic did a valve clearance check and said it was OK and when I asked him about the clearances he said that they were 6 thousands and 9 thousands however in my book the measurements are different they are as follow: ( i don't understand what he meant by thousands)inlet: 0.10~0.140.15~0.19 exhaust: 0.14~0.190.20~0.24so did he just make it up or did he get the wrong measurement.: The exhaust valves get hotter--the reason for looser clearances.Buster Brown is right about the rest.
